(R. N. B.)

ERICACEAE,in botany, a natural order of plants belonging to the higher or gamopetalous division of Dicotyledons. They are woody plants, sometimes with a slender creeping stem as in bilberry,Vaccinium(fig. 1), orAndromeda(fig. 2), or forming low bushes as in the heaths, or larger, sometimes becoming tree-like, as in species ofRhododendron. The leaves are alternate, opposite or whorled in arrangement, and in their form and structure show well-marked adaptation for life in dry or exposed situations. Thus in the true heaths they are needle-like, with the margins often rolled back to form a groove or an almost closed chamber on the under side. In others such asRhododendronorArbutusthey are often leathery and evergreen, the strongly cuticularized upper surface protecting a water-storing tissue situated above the green layers of the leaf. The flowers are sometimes solitary and axillary or terminal as inAndromeda, but are generally arranged in racemose inflorescences at the end of the branches as inArbutusandRhododendron, or on small lateral shoots as inErica. They are hermaphrodite and generally regular with parts in 4 or 5, thus: sepals 4 or 5, petals 4 or 5, stamens 8 or 10 in two series, the outer of which is opposite the petals, and carpels 4 or 5. The corolla is usually more or less bell-shaped, and in the heaths persists in a dry state in the fruit. The petals with the stamens are situated on the outer edge of a honey-secreting disk. The anthers show a very great variety in shape, the halves are often more or less free and often appendaged; they open to allow the escape of the pollen by a terminal pore or slit. The carpels are united to form a 4- to 5-chambered ovary, which bears a simple elongated style ending in a capitate stigma; each ovary-chamber contains one to many ovules attached to a central placenta. The brightly coloured corolla, the presence of nectar and the scent render the flowers attractive to insects, and the projection of the stigma beyond the anthers favours crossing. The fruit is generally a capsule containing many seeds, as inErica(fig. 3) orRhododendron; sometimes a berry as inArbutus.

1, Flowering shoot ofErica cinerea, about 1½ nat. size.

2, Flower cut lengthwise.

3, Stamen showing appendages and porous dehiscence of anther.

4, Capsule showing the loculicidal dehiscence; a few seeds remain attached to the central axis.

5, Diagram of the flower having four sepals, four divisions of the corolla, eight stamens in two rows, and four divisions of the pistil.

The order falls into four distinct tribes, which are characterized by the relative position of the ovary and by the fruit and seed. They are as follows:—

1.Rhododendron tribe,characterized by capsular fruit, seed with a loose coat, deciduous petals and anthers without appendages. It consists mainly of the great genusRhododendron(in whichAzaleais included by recent botanists), which is chieflydeveloped in the mountains of eastern Asia, many species occurring on the Himalayas.Dabeocia, St Dabeoc’s heath, occurs in Ireland.

2.Arbutus Tribe.—Fruit a berry or capsule, petals deciduous and anthers with bristle-like appendages, chiefly north temperate to arctic in distribution.Arbutus Unedo, the strawberry-tree, so called from its large scarlet berry, is a southern European species which extends into south Ireland.Arctostaphylos(bearberry) andAndromedaare arctic and alpine genera occurring in Britain.Epigaea repensis the trailing arbutus or mayflower of Atlantic America.

3.Vaccinium Tribe.—Ovary inferior, fruit a berry. Extends from the north temperate zone to the mountains of the tropics.Vaccinium, the largest genus, has four British species:V. Myrtillusis the bilberry(q.v.), blaeberry or whortleberry,V. Vitis-Idaeathe cowberry, andV. Oxycoccosthe cranberry (q.v.). This tribe is sometimes regarded as a separate order Vacciniaceae, distinguished by its inferior ovary.

4.Erica Tribe.—Fruit usually a capsule, seeds round, not winged; corolla persisting round the ripe fruit; anthers often appendaged. The largest genus isErica, the true heath (q.v.), with over 400 species, the great majority of which are confined to the Cape; others occur on the mountains of tropical Africa and in Europe and North Africa, especially the Mediterranean region.E. cinerea(purple heather) andE. Tetralix(cross-leaved heath) are common British heaths.Callunais the ling or Scotch heather.

ERICHSEN, SIR JOHN ERIC,Bart. (1818-1896), British surgeon, born on the 19th of July 1818 at Copenhagen, was the son of Eric Erichsen, a member of a well-known Danish family. He studied medicine at University College, London, and at Paris, devoting himself in the early years of his career to physiology, and lecturing on general anatomy and physiology at University College hospital. In 1844 he was secretary to the physiological section of the British Association, and in 1845 he was awarded the Fothergillian gold medal of the Royal Humane Society for his essay on asphyxia. In 1848 he was appointed assistant surgeon at University College hospital, and in 1850 became full surgeon and professor of surgery, his lectures and clinical teaching being much admired; and in 1875 he joined the consulting staff. HisScience and Art of Surgery(1853) went through many editions. He rose to be president of the College of Surgeons in 1880. From 1879 to 1881 he was president of the Royal Medical and Chirurgical Society. He was created a baronet in 1895, having been for some years surgeon-extraordinary to Queen Victoria. As a surgeon his reputation was world-wide, and he counts (says Sir W. MacCormac in his volume on the Centenary of the Royal College of Surgeons) “among the makers of modern surgery.” He was a recognized authority on concussion of the spine, and was often called to give evidence in court on obscure cases caused by railway accidents, &c. He died at Folkestone on the 23rd of September 1896.

ERICHT, LOCH,a lake partly in Inverness-shire and partly in Perthshire, Scotland, lying between the districts of Badenoch on the N. and Rannoch on the S. The boundary line is drawn from a point opposite to the mouth of the Alder, and follows the centre of the longitudinal axis north-eastwards to 56° 50′ N., where it strikes eastwards to the shore. All of the lake to the S. and E. of this line belongs to Perthshire, the rest, forming the major portion, to Inverness-shire. It is a lonely lake, situated in extremely wild surroundings at a height of 1153 ft. above the sea, being thus the loftiest lake of large size in the United Kingdom. It is over 14½ m. long, with a mean breadth of half a mile and over 1 m. at its maximum. Its area amounts to some 7¼ sq. m., and it receives the drainage of an area of nearly 50½ sq. m. The mean depth is 189 ft., and the maximum 512 ft. It has a general trend from N.E. to S.W., the head lying 1 m. from Dalwhinnie station on the Highland railway. It receives many streams, and discharges at the south-western extremity by the Ericht. Salmon and trout afford good fishing. The surrounding mountains are lofty and rugged. Ben Alder (3757 ft.) on the west shore is the chief feature of the great Corrour deer forest. The only point of interest on the banks is the cavern, near the mouth of the Alder, in which Prince Charles Edward concealed himself for a time after the battle of Culloden.

ERICSSON, JOHN(1803-1889), Swedish-American naval engineer, was born at Langbanshyttan, Wermland, Sweden, on the 31st of July 1803. He was the second son of Olaf Ericsson, an inspector of mines, who died in 1818. Showing from his earliest years a strong mechanical bent, young Ericsson, at the age of twelve, was employed as a draughtsman by the Swedish Canal Company. From 1820 to 1827 he served in the army, where his drawing and military maps attracted the attention of the king, and he soon attained the rank of captain. In 1826 he went to London, at first on leave of absence from his regiment, and in partnership with John Braithwaite constructed the “Novelty,” a locomotive engine for the Liverpool & Manchester railway competition at Rainhill in 1829, when the prize, however, was won by Stephenson’s “Rocket.” The number of Ericsson’s inventions at this period was very great. Among other things he worked out a plan for marine engines placed entirely below the water-line. Such engines were made for the “Victory,” for Captain (afterwards Sir) John Ross’s voyage to the Arctic regions in 1829, but they did not prove satisfactory. In 1833 his caloric engine was made public. In 1836 he took out a patent for a screw-propeller, and though the priority of his invention could not be maintained, he was afterwards awarded a one-fifth share of the £20,000 given by the Admiralty for it. At this time Captain Stockton, of the United States navy, gave an order for a small iron vessel to be built by Laird of Birkenhead, and to be fitted by Ericsson with engines and screw. This vessel reached New York in May 1839. A few months later Ericsson followed his steamer to New York, and there he resided for the rest of his life, establishing himself as an engineer and a builder of iron ships. In 1848 he was naturalized as a citizen of the United States. He had many difficulties to contend with, and it was only by slow degrees that he established his fame and won his way to competence. At his death he seems to have been worth about £50,000. The provision of defensive armour for ships of war had long occupied his attention, and he had constructed plans and a model of a vessel lying low in the water, carrying one heavy gun in a circular turret mounted on a turntable. In 1854 he sent his plans to the emperor of the French. Louis Napoleon, however, acting probably on the advice of Dupuy de Lôme, declined to use them. The American Civil War, and the report that the Confederates were converting the “Merrimac” into an ironclad, caused the navy department to invite proposals for the construction of armoured ships. Among others, Ericsson replied, and as it was thought that his design might be serviceable in inland waters, the first armoured turret ship, the “Monitor,” was ordered; she was launched on the 30th of January 1862, and on the 9th of March she fought the celebrated action with the Confederate ram “Merrimac.” The peculiar circumstances in which she was built, the great importance of the battle, and the decisive nature of the result gave the “Monitor” an exaggerated reputation, which further experience did not confirm. In later years Ericsson devoted himself to the study of torpedoes and sun motors. He publishedSolar Investigations(New York, 1875) andContributions to the Centennial Exhibition(New York, 1877). He died in New York on the 8th of March 1889, and in the following year, on the request of the Swedish government, his body was sent to Stockholm and thence into Wermland, where, at Filipstad, it was buried on the 15th of September.

ALife of Ericssonby William Conant Church was published in New York in 1890 and in London in 1893.

ERIDANUS,orFluvius(“the river”), in astronomy, a constellation of the southern hemisphere, mentioned by Eudoxus (4th centuryB.C.) and Aratus (3rd centuryB.C.); Ptolemy catalogued 34 stars in it. θEridani, a fine double star of magnitudes 3.5 and 5.5, is now of the third magnitude. It is supposed to be identical with theAchernarof Al-Sufi, who described it as of the first magnitude; this star has therefore decreased in brilliancy in historic times. The star ο2Eridani(numbered 40by Flamsteed) was discovered to be a ternary star group by Herschel in 1783; it consists of a close pair, of magnitudes 9.2 and 10.9, revolving in a period of 180 years, associated with a star of magnitude 4.5, which is distant from the pair by 82″; these stars have an exceptionally swift proper motion, about 4″ per annum. Eridanus was the ancient name of the river Po.

ERIDU,one of the oldest religious centres of the Sumerians, described in the ancient Babylonian records as the “city of the deep.” The special god of this city was Ea (q.v.), god of the sea and of wisdom, and the prominence given to this god in the incantation literature of Babylonia and Assyria suggests not only that many of our magical texts are to be traced ultimately to the temple of Ea at Eridu, but that this side of the Babylonian religion had its origin in that place. Certain of the most ancient Babylonian myths, especially that of Adapa, may also be traced back to the shrine of Ea at Eridu. But while of the first importance in matters of religion, there is no evidence in Babylonian literature of any special political importance attaching to Eridu, and certainly at no time within our knowledge did it exercise hegemony in Babylonia. The site of Eridu was discovered by J.E. Taylor in 1854, in a ruin then called by the natives Abu-Shahrein, a few miles south-south-west of Moghair, ancient Ur, nearly in the centre of the dry bed of an inland sea, a deep valley, 15 m. at its broadest, covered for the most part with a nitrous incrustation, separated from the alluvial plain about Moghair by a low, pebbly, sandstone range, called the Hazem, but open toward the north to the Euphrates and stretching southward to the Khanega wadi below Suk-esh-Sheiukh. In the rainy season this valley becomes a sea, flooded by the discharge of the Khanega; in summer the Arabs dig holes here which supply them with brackish water. The ruins, in which Taylor conducted brief excavations, consist of a platform of fine sand enclosed by a sandstone wall, 20 ft. high, the corners toward the cardinal points, on the N.W. part of which was a pyramidal tower of two stages, constructed of sun-dried brick, cased with a wall of kiln-burned brick, the whole still standing to a height of about 70 ft. above the platform. The summit of the first stage was reached by a staircase on the S.E. side, 15 ft. wide and 70 ft. long, constructed of polished marble slabs, fastened with copper bolts, flanked at the foot by two curious columns. An inclined road led up to the second stage on the N.W. side. Pieces of polished alabaster and marble, with small pieces of pure gold and gold-headed copper nails, found on and about the top of the second stage, indicated that a small but richly adorned sacred chamber, apparently plated within or without in gold, formerly crowned the top of this structure. Around the whole tower was a pavement of inscribed baked bricks, resting on a layer of clay 2 ft. thick. On the S.E. part of the terrace were the remains of several edifices, containing suites of rooms. Inscriptions on the bricks identified the site as that of Eridu. Since Taylor’s time the place has not been visited by any explorer, owing to the unsafe condition of the neighbourhood; but T.K. Loftus (1854) and J.P. Peters (1890) both report having seen it from the summit of Moghair. The latter states that the Arabs at that time called the ruin Nowawis, and apparently no longer knew the name Abu-Shahrein. Through an error, in many recent maps and Assyriological publications Eridu is described as located in the alluvial plain, between the Tigris and the Euphrates. It was, in fact, an island city in an estuary of the Persian Gulf, stretching up into the Arabian plateau. Originally “on the shore of the sea,” as the old records aver, it is now about 120 m. from the head of the Persian Gulf. Calculating from the present rate of deposit of alluvium at the head of that gulf, Eridu should have been founded as early as the seventh millenniumB.C.It is mentioned in historical inscriptions from the earliest times onward, as late as the 6th centuryB.C.From the evidence of Taylor’s excavations, it would seem that the site was abandoned about the close of the Babylonian period.

ERIE,the most southerly of the Great Lakes of North America, between 41° 23′ and 42° 53′ N., and 78° 51′ and 83° 28′ W., bounded W. by the state of Michigan, S. and S.E. by Ohio, Pennsylvania and New York, and N. by the province of Ontario. It is nearly elliptical, the major axis, 250 m. long, lying east and west; its greatest breadth is 60 m.; its area about 10,000 sq. m.; and the total area of its basin 34,412 sq. m. Its elevation above mean sea-level is 573 ft.; and its surface is nearly 9 ft. below that of Lake Huron, which discharges into it through St Clair river, Lake St Clair and Detroit river, and is 327 ft. above that of Lake Ontario, this great difference being absorbed by the rapids and falls in the Niagara river, which joins the two lakes. Lake Erie is very shallow, and may be divided into three basins, the western extending to Point Pelee and including all the islands, containing about 1200 sq. m., with a comparatively flat bottom at 5 to 6 fathoms; the main basin, between Point Pelee and the narrows at Long Point, containing about 6700 sq. m., and having a marked shelving bottom deepening gradually to 14 fathoms; and the portion east of the narrows, containing about 2100 sq. m., having a depression 30 fathoms deep just east from Long Point, with an extensive flat of 11 fathoms depth between it and the main basin. The Canadian shore is low and flat throughout, the United States shore is low but bordered by an elevated plateau through which the rivers have cut deep channels. The lake basin is relatively so small that the rivers are without importance; Grand river, on the north shore, is the largest tributary. The flat alluvial soil bordering on the lake is very fertile, and the climate is well adapted for fruit cultivation. Large quantities of peaches, grapes and small fruits are grown; the islands in the west end have a climate much warmer and more equable than the adjoining mainland, and are practically covered with vineyards. The low clayey or sandy shores are subject to erosion by waves. In severe storms the water near shore is filled with sand, which is deposited where the currents are checked around the ends of jetties in such a way as to form bars out into the lake across improved channels. This shoaling has rendered continuous dredging necessary at every harbour on the lake west of Erie, Pa. In consequence of the shallowness of the lake its waters are easily disturbed, making navigation very rough and dangerous, and causing large fluctuations of surface. Strong winds are frequent, as nearly every cyclonic depression traversing North America, either from the westward or the Gulf of Mexico, passes near enough to Lake Erie to be felt. Westerly gales are more frequent, and have more effect on the water surface than easterly ones, lowering the water as much as 7 to 8 ft. at the west end and raising it 5 to 8 ft. at the east end. The worst storms occur in autumn, when the immense quantity of shipping on the lake makes them specially destructive. There are no tides, and usually only a slight current towards the outlet, though powerful currents are temporarily produced by the rapid return of waters after a storm, and during the height of a westerly gale there is invariably a reflex current into the west end of the lake. There is an annual fluctuation in the level of the lake, varying from a minimum of 9 in. to a maximum of 2 ft., the normal low level occurring in February and the high level in midsummer. Standard high water (of 1838) is 575.11 ft. above mean sea-level, and the lowest record was 570.8 in November 1895. The harbours and exits of the lake freeze over, but the body of the lake never freezes completely.

Ice-breaking car ferries run across the lake all winter. General navigation opens as a rule in the middle of April and closes in the middle of December. The volume of traffic is immense, because practically all freight from the more westerly lakes finds terminal harbours in Lake Erie. Official statistics of commerce passing through the Detroit river into the lake during the season of 1906 show that 35,128 vessels, having a net register of 50,673,897 tons, carried 63,805,571 (short) tons of freight, valued at $662,971,053. The 1175 vessels engaged in this business were valued at $106,223,000. Over 90% of the whole traffic is in United States ships to United States ports. Fine passenger steamers run nightly between Buffalo and Cleveland and Detroit, and there are many shorter passenger routes.

The large traffic on Lake Erie has brought into existence a number of important harbours on the south shore, nearly all artificially made and deepened, with entrances between two breakwaters running into the lake at right angles to the coast line. The principal of these are Toledo, Sandusky, Huron, Vermilion, Lorain, Cleveland, Fairport, Ashtabula, Conneaut, Erie (a natural harbour), Dunkirk and Buffalo, Rondeau, Port Stanley, Port Burwell, Port Dover, Port Maitland and Port Colborne. The Miami and Erie canal, leading from Maumee river to Cincinnati, 244½ m., with a branch to Port Jefferson, 14 m., with locks 90 by 15 by 4 ft., connects with Lake Erie through Toledo. The Erie canal leading from Buffalo to the Hudson river at Troy, and connecting with Lake Ontario at Oswego, had a capacity for boats 98 ft. long, 17 ft. 10 in. beam, with 6 ft. draught, until in 1907 the State of New York undertook its deepening to accommodate boats of 1000 tons capacity. Buffalo from its position at the eastern limit of deep draught lake navigation is a city of first rate commercial importance. Its harbour is formed by an artificial breakwater, built parallel with the shore about half a mile distant from it. It receives practically all the Lake Erie grain shipments besides large quantities of iron ore, lumber and copper, and is a large shipping port for coal, principally anthracite. It has over 600 m. of railway tracks to accommodate lake freights. The Welland canal, 26¾ m. long, connecting Lake Ontario and Lake Erie, with locks 270 by 45 by 14 ft., leaves Lake Erie at Port Colborne, where the Canadian government have constructed an artificial harbour and elevators for transhipment of grain from upper lake freighters to lighters of canal capacity.

Fishing operations are carried on extensively in Lake Erie, the fish being taken with gill nets, seines and pound nets. Each state touching the lake has its own fishery regulations, which differ amongst themselves as well as from those of the Dominion. Both nations maintain a Fishery Protection Service, and the fisheries are replenished from artificial hatcheries. The most numerous and valuable fish are the lesser white fish (Coregonus artedi, Le Sueur), pickerel (Stizostedion vitreum, Walb.), pike (Lucius lucius, L.), and white fish (Coregonus clupeiformis, Mitchill), in the order named. The fish caught are estimated to be worth annually $1,000,000. They are collected in fishing tugs and distributed by rail throughout the United States and Canada.

ERIE,a city, a port of entry, and the county-seat of Erie county, Pennsylvania, U.S.A., on Lake Erie, 148 m. by rail N. of Pittsburg and near the N.W. corner of the state. Pop. (1890) 40,634; (1900) 52,733, of whom 11,957 were foreign-born, including 5226 from Germany and 1468 from Ireland, and 26,797 were of foreign parentage (both parents foreign-born), including 13,316 of German parentage and 4203 of Irish parentage; (1910 census) 66,525. Erie is served by the New York, Chicago & St Louis, the Lake Shore & Michigan Southern, the Erie & Pittsburg (Pennsylvania Company), the Philadelphia & Erie (Pennsylvania railway), and the Bessemer & Lake Erie railways, and by steamboat lines to many important lake ports. The city extends over an area of about 7 sq. m., which for the most part is quite level and is from 50 to 175 ft. above the lake. Erie has a fine harbour about 4 m. in length, more than 1 m. in width, and with an average depth of about 20 ft.; it is nearly enclosed by Presque Isle, a long narrow strip of land of about 3000 acres from 300 ft. to 1 m. in width, and the national government has protected its entrance and deepened its channel by constructing two long breakwaters. Most of the streets of the city are 60 ft. wide—a few are 100 ft.—and nearly all intersect at right angles; they are paved with brick and asphalt, and many in the residential quarters are shaded with fine elms and maples. The city has four parks, in one of which is a soldiers’ and sailors’ monument of granite and bronze, and not far away, along the shore of lake and bay, are several attractive summer resorts. Among Erie’s more prominent buildings are the United States government building, the city hall, the public library, and the county court house. The city’s charitable institutions consist of two general hospitals, each of which has a training school for nurses; a municipal hospital, an orphan asylum, a home for the friendless, two old folks’ homes, and a bureau of charities; here, also, on a bluff, within a large enclosure and overlooking both lake and city, is the state soldiers’ and sailors’ home, and near by is a monument erected to the memory of General Anthony Wayne, who died here on the 15th of December 1796.

Erie is the commercial centre of a large and rich grape-growing and agricultural district, has an extensive trade with the lake ports and by rail (chiefly in coal, iron ore, lumber and grain), and is an important manufacturing centre, among its products being iron, engines, boilers, brass castings, stoves, car heaters, flour, malt liquors, lumber, planing mill products, cooperage products, paper and wood pulp, cigars and other tobacco goods, gas meters, rubber goods, pipe organs, pianos and chemicals. In 1905 the city’s factory products were valued at $19,911,567, the value of foundry and machine-shop products being $6,723,819, of flour and grist-mill products $1,444,450, and of malt liquors $882,493. The municipality owns and operates its water-works.

On the site of Erie the French erected Fort Presque Isle in 1753, and about it founded a village of a few hundred inhabitants. George Washington, on behalf of the governor of Virginia, came in the same year to Fort Le Bœuf (on the site of the present Waterford), 20 m. distant, to protest against the French fortifying this section of country. The protest, however, was unheeded. The village was abandoned in or before 1758, owing probably to an epidemic of smallpox, and the fort was abandoned in 1759. It was occupied by the British in 1760, but on the 22nd of June 1763 this was one of the several forts captured by the Indians during the Conspiracy of Pontiac. In 1764 the British regained nominal control and retained it until 1785, when it passed into the possession of the United States. The place was laid out as a town in 1795; in 1800 it became the county-seat of the newly-erected county of Erie; it was incorporated as a borough in 1805, the charter of that year being revised in 1833; and in 1851 it was incorporated as a city. At Erie were built within less than six months most of the vessels with which Commodore Oliver H. Perry won his naval victory over the British off Put-in-Bay on the 10th of September 1813.

ERIGENA, JOHANNES SCOTUS(c.800-c.877), medieval philosopher and theologian. His real name was Johannes Scotus (Scottus) or John the Scot. The combination Johannes Scotus Erigena has not been traced earlier than Ussher and Gale; even Gale uses it only in the heading of the version of St Maximus. The date of Erigena’s birth is very uncertain, and there is no evidence to show definitely where he was born. The name Scotus, which has often been taken to imply Scottish origin, really favours the theory that he was an Irishman according to the then usage ofScotusorScotigena. Prudentius, bishop of Troyes, definitely states that he was of Irish extraction. The pseudonym commonly read Erigena, used by himself in the titles of his versions of Dionysius the Areopagite, isIerugena(in later MSS. Erugena and Eriugena), formed apparently on the analogy ofGraiugena(“Greek-born”), which he applies to St Maximus. There seems no reason to doubt that Eriugena is connected with Erin, the name for Ireland, and Ierugena suggests the Greekἱερός, ἱερὸς, νῆσοςbeing a common name for Ireland. On the other hand, William of Malmesbury prefers to read Heruligena, which would make Scotus a Pannonian, while Bale says he was born at St David’s, Dempster connects him with Ayr, and Gale with Eriuven in Hereford. Some early writers thought there were two persons, John Scotus and John Erigena.

Of Erigena’s early life nothing is known. Bale quotes the story that he travelled in Greece, Italy and Gaul, and studiednot only Greek, but also Arabic and Chaldaean. Since, however, Bale describes him as “ex patricio genitore natus,” it is a reasonable inference (so R.L. Poole) that Bale confused him with one John, the son of Patricius, a Spaniard, who tells much the same story of his own travels. The knowledge of Greek displayed in Erigena’s works is not such as to compel us to conclude that he had actually visited Greece. That he had a competent acquaintance with Greek is manifest from his translations of Dionysius the Areopagite and of Maximus, from the manner in which he refers to Aristotle, and from his evident familiarity with Neoplatonist writers and the fathers of the early church. Roger Bacon, in his severe criticism on the ignorance of Greek displayed by the most eminent scholastic writers, expressly exempts Erigena, and ascribes to him a knowledge of Aristotle in the original.

Among other legends which have at various times been attached to Erigena are that he was invited to France by Charlemagne, and that he was one of the founders of the university of Paris. The only portion of Erigena’s life as to which we possess accurate information was that spent at the court of Charles the Bald. Charles invited him to France soon after his accession to the throne, probably in the year 843, and placed him at the head of the court school (schola palatina). The reputation of this school seems to have increased greatly under Erigena’s leadership, and the philosopher himself was treated with indulgence by the king. William of Malmesbury’s amusing story illustrates both the character of Scotus and the position he occupied at the French court. The king having asked, “Quid distat inter sottum et Scottum?” Erigena replied, “Mensa tantum.”

The first of the works known to have been written by Erigena during this period was a treatise on the eucharist, which has not come down to us (by some it has been identified with a treatise by Ratramnus,De corpore et sanguine Domini). In it he seems to have advanced the doctrine that the eucharist was merely symbolical or commemorative, an opinion for which Berengarius was at a later date censured and condemned. As a part of his penance Berengarius is said to have been compelled to burn publicly Erigena’s treatise. So far as we can learn, however, Erigena’s orthodoxy was not at the time suspected, and a few years later he was selected by Hincmar, archbishop of Reims, to defend the doctrine of liberty of will against the extreme predestinarianism of the monk Gottschalk (Gotteschalchus). The treatiseDe divina praedestinatione, composed on this occasion, has been preserved, and from its general tenor one cannot be surprised that the author’s orthodoxy was at once and vehemently suspected. Erigena argues the question entirely on speculative grounds, and starts with the bold affirmation that philosophy and religion are fundamentally one and the same—“Conficitur inde veram esse philosophiam veram religionem, conversimque veram religionem esse veram philosophiam.” Even more significant is his handling of authority and reason, to which we shall presently refer. The work was warmly assailed by Drepanius Florus, canon of Lyons, and Prudentius, and was condemned by two councils—that of Valence in 855, and that of Langres in 859. By the former council his arguments were described asPultes Scotorum(“Scots porridge”) andcommentum diaboli(“an invention of the devil”).

Erigena’s next work was a Latin translation of Dionysius the Areopagite (seeDionysius Areopagiticus) undertaken at the request of Charles the Bald. This also has been preserved, and fragments of a commentary by Erigena on Dionysius have been discovered in MS. A translation of the Areopagite’s pantheistical writings was not likely to alter the opinion already formed as to Erigena’s orthodoxy. Pope Nicholas I. was offended that the work had not been submitted for approval before being given to the world, and ordered Charles to send Erigena to Rome, or at least to dismiss him from his court. There is no evidence, however, that this order was attended to.

The latter part of his life is involved in total obscurity. The story that in 882 he was invited to Oxford by Alfred the Great, that he laboured there for many years, became abbot at Malmesbury, and was stabbed to death by his pupils with their “styles,” is apparently without any satisfactory foundation, and doubtless refers to some other Johannes. Erigena in all probability never left France, and Hauréau has advanced some reasons for fixing the date of his death about 877.

Erigena is the most interesting figure among the middle-age writers. The freedom of his speculation, and the boldness with which he works out his logical or dialectical system of the universe, altogether prevent us from classing him along with the scholastics properly so called. He marks, indeed, a stage of transition from the older Platonizing philosophy to the later and more rigid scholasticism. In no sense whatever can it be affirmed that with Erigena philosophy is in the service of theology. The above-quoted assertion as to the substantial identity between philosophy and religion is indeed repeated almosttotidem verbisby many of the later scholastic writers, but its significance altogether depends upon the selection of one or other term of the identity as fundamental or primary. Now there is no possibility of mistaking Erigena’s position: to him philosophy or reason is first, is primitive; authority or religion is secondary, derived. “Auctoritas siquidem ex vera ratione processit, ratio vero nequaquam ex auctoritate. Omnis enim auctoritas, quae vera ratione non approbatur, infirma videtur esse. Vera autem ratio, quum virtutibus suis rata atque immutabilis munitur, nullius auctoritatis adstipulatione roborari indiget” (De divisione naturae, i. 71). F.D. Maurice, the only historian of note who declines to ascribe a rationalizing tendency to Erigena, obscures the question by the manner in which he states it. He asks his readers, after weighing the evidence advanced, to determine “whether he (Erigena) used his philosophy to explain away his theology, or to bring out what he conceived to be the fullest meaning of it.” These alternatives seem to be wrongly put. “Explaining away theology” is something wholly foreign to the philosophy of that age; and even if we accept the alternative that Erigena endeavours speculatively to bring out the full meaning of theology, we are by no means driven to the conclusion that he was primarily or principally a theologian. He does not start with the datum of theology as the completed body of truth, requiring only elucidation and interpretation; his fundamental thought is that of the universe, nature,τὸ πᾶν, or God, as the ultimate unity which works itself out into the rational system of the world. Man and all that concerns man are but parts of this system, and are to be explained by reference to it; for explanation or understanding of a thing is determination of its place in the universal or all. Religion or revelation is one element or factor in the divine process, a stage or phase of the ultimate rational life. The highest faculty of man, reason,intellectus,intellectualis visio, is that which is not content with the individual or partial, but grasps the whole and thereby comprehends the parts. In this highest effort of reason, which is indeed God thinking in man, thought and being are at one, the opposition of being and thought is overcome. When Erigena starts with such propositions, it is clearly impossible to understand his position and work if we insist on regarding him as a scholastic, accepting the dogmas of the church as ultimate data, and endeavouring only to present them in due order and defend them by argument.

Erigena’s great work,De divisione naturae, which was condemned by a council at Sens, by Honorius III. (1225), who described it as “swarming with worms of heretical perversity,” and by Gregory XIII. in 1585, is arranged in five books. The form of exposition is that of dialogue; the method of reasoning is the syllogistic. The leading thoughts are the following.Naturais the name for the universal, the totality of all things, containing in itself being and non-being. It is the unity of which all special phenomena are manifestations. But of this nature there are four distinct classes:—(1) that which creates and is not created; (2) that which is created and creates; (3) that which is created and does not create; (4) that which neither is created nor creates. The first is God as the ground or origin of all things, the last is God as the final end or goal of all things, that into which the world of created things ultimately returns. The second and third together compose the created universe, which is the manifestation of God, Godin processu,Theophania. Thus we distinguish in the divine system beginning, middle and end; but these three are in essence one—the difference is only the consequence of our finite comprehension. We are compelled to envisage this eternal process under the form of time, to apply temporal distinctions to that which is extra- or supra-temporal.The universe of created things, as we have seen, is twofold:—first, that which is created and creates—the primordial ideas, archetypes, immutable relations, divine acts of will, according to which individual things are formed;second, that which is created and does not create, the world of individuals, the effects of the primordial causes, without which the causes have no true being. Created things have no individual or self-independent existence; they are only in God; and each thing is a manifestation of the divine,theophania,divina apparitio.God alone, the uncreated creator of all, has true being. He is the true universal, all-containing and incomprehensible. The lower cannot comprehend the higher, and therefore we must say that the existence of God is above being, above essence; God is above goodness, above wisdom, above truth. No finite predicates can be applied to him; his mode of being cannot be determined by any category. True theology is negative. Nevertheless the world, as thetheophania, the revelation of God, enables us so far to understand the divine essence. We recognize his being in the being of all things, his wisdom in their orderly arrangement, his life in their constant motion. Thus God is for us a Trinity—the Father as substance or being (οὐσία), the Son as wisdom (δύναμις), the Spirit as life (ἐνέργια). These three are realized in the universe—the Father as the system of things, the Son as the word,i.e.the realm of ideas, the Spirit as the life or moving force which introduces individuality and which ultimately draws back all things into the divine unity. In man, as the noblest of created things, the Trinity is seen most perfectly reflected;intellectus(νοῦς),ratio(λογος) andsensus(διάνοια) make up the threefold thread of his being. Not in man alone, however, but in all things, God is to be regarded as realizing himself, as becoming incarnate.The infinite essence of God, which may indeed be described asnihilum(nothing) is that from which all is created, from which all proceeds or emanates. The first procession or emanation, as above indicated, is the realm of ideas in the Platonic sense, the word or wisdom of God. These ideas compose a whole or inseparable unity, but we are able in a dim way to think of them as a system logically arranged. Thus the highest idea is that ofgoodness; things are, only if they are good; being without well-being is naught.Essenceparticipates in goodness—that which is good has being, and is therefore to be regarded as a species of good.Life, again, is a species of essence,wisdoma species of life, and so on, always descending from genus to species in a rigorous logical fashion.The ideas are the eternal causes, which, under the moving influence of the spirit, manifest themselves in their effects, the individual created things. Manifestation, however, is part of the being or essence of the causes, that is to say, if we interpret the expression, God of necessity manifests himself in the world and is not without the world. Further, as the causes are eternal, timeless, so creation is eternal, timeless. The Mosaic account, then, is to be looked upon merely as a mode in which is faintly shadowed forth what is above finite comprehension. It is altogether allegorical, and requires to be interpreted. Paradise and the Fall have no local or temporal being. Man was originally sinless and without distinction of sex. Only after the introduction of sin did man lose his spiritual body, and acquire the animal nature with its distinction of sex. Woman is the impersonation of man’s sensuous and fallen nature; on the final return to the divine unity, distinction of sex will vanish, and the spiritual body will be regained.The most remarkable and at the same time the most obscure portion of the work is that in which the final return to God is handled. Naturally sin is a necessary preliminary to this redemption, and Erigena has the greatest difficulty in accounting for the fact of sin. If God is true being, then sin can have no substantive existence; it cannot be said that God knows of sin, for to God knowing and being are one. In the universe of things,asa universe, there can be no sin; there must be perfect harmony. Sin, in fact, results from the will of the individual who falsely represents something as good which is not so. This misdirected will is punished by finding that the objects after which it thirsts are in truth vanity and emptiness. Hell is not to be regarded as having local existence; it is the inner state of the sinful will. As the object of punishment is not the will or the individual himself, but the misdirection of the will, so the result of punishment is the final purification and redemption of all. Even the devils shall be saved. All, however, are not saved at once; the stages of the return to the final unity, corresponding to the stages in the creative process, are numerous, and are passed through slowly. The ultimate goal isdeificatio,theosisor resumption into the divine being, when the individual soul is raised to a full knowledge of God, and where knowing and being are one. After all have been restored to the divine unity, there is no further creation. The ultimate unity is that which neither is created nor creates.Editions.—There is a complete edition of Erigena’s works in J.P. Migne’sPatrologiae cursus completus(vol. cxxii.), edited by H.J.
