The Cistercian Abbey of Adwert near Groningen, under the enlightened governance of Henry of Rees (1449-85), was a centre to which were attracted most of the scholars whose names are famous in the history of Northern humanism in the second half of the fifteenth century: Wessel, Agricola, Hegius, Langen, Vrye, and others. They came on return from visits to Italy or the universities; men of affairs after discharge of their missions; schoolmasters to rest on their holidays; parish priests in quest of change: all found a welcome from the hospitable Abbot, and their talk ranged far and wide, over the pursuit of learning, till Adwert merited the name of an 'Academy'.
Earliest of these is John Wessel († 1489), and perhaps also the most notable; certainly the others looked up to him with a veneration which seems to transcend the natural pre-eminence of seniority. Unfortunately the details of his life have not been fully established. Thirty years after his death, when it was too late for him to define his own views, the Reformers claimed him for their own; and in consequence his body has been wrangled over with the heat which seeks not truth but victory. His father, Hermann Wessel, was a baker from the Westphalian village of Gansfort or Goesevort, who settled in Groningen. After some years in the town school, the boy was about to be apprenticed to a trade, as his parents were too poor to help him further; but the good Oda Jargis, hearing how well he had done at his books, sent him to the school at Zwolle, in which the Brethren of the Common Life took part. There, as at Groningen, he rose to the top, and in his last years, as a first-form boy, also did some teaching in the third form, according to the custom of the school. He came into contact with Thomas à Kempis, who was then at the monastery of Mount St. Agnes, half an hour outside Zwolle, and was profoundly influenced by him. The course at Zwolle lasted eight years, and there is reason to suppose that he completed it in full. He was lodged in the Parua Domus, a hostel for fifty boys, and we are told that he and his next neighbour made a hole through the wall which divided their rooms—probably only a wooden partition—and taught one another: Wessel imparting earthly wisdom, and receiving in exchange the fear and love of the Lord. In the autumn of 1449 he matriculated at Cologne, entering the Bursa Laurentiana; in December 1450 he was B.A., and in February 1452, M.A.
By 1455 he had arrived at Paris and entered upon his studies for the theological degree. Within a year he conceived a profound distaste for the philosophy dominant in the schools; and though he persevered for some time, his frequent dissension from his teachers earned for him the title of 'Magister contradictionis'. After this his movements cannot be traced until 1470, when he was at Rome in the train of Cardinal Francesco della Rovere. In the interval he studied medicine, and, if report be true, travelled far; venturing into the East, just when the fall of Constantinople had turned the tide of Hellenism westward. In Greece he read Aristotle in the original, and learnt to prefer Plato; in Egypt he sought in vain for the books of Solomon and a mythical library of Hebrew treasures.
In 1471 his Cardinal-patron was elected Pope as Sixtus IV. The magnificence which characterized the poor peasant's son in his dealings with Italy, in his embellishment of Rome and the Vatican, was not lacking in his treatment of Wessel. 'Ask what you please as a parting gift', he said to the scholar, who was preparing to set out for Friesland. 'Give me books from your library, Greek and Hebrew', was the request. 'What? No benefice, no grant of office or fees? Why not?' 'Because I don't want them', came the quiet reply. The books were forthcoming—one, a Greek Gospels, was perhaps the parent of a copy which reached Erasmus for the second edition of his New Testament.
After his return to the North, Wessel was invited to Heidelberg, to aid the Elector Palatine, Philip, in restoring the University, c. 1477. He was without the degree in theology which would have enabled him to teach in that faculty, and was not even in orders: indeed a proposal that he should qualify by entering the lowest grade and receiving the tonsure, he contemptuously rejected. So the Theological Faculty would not hear him, but to the students in Arts he lectured on Greek and Hebrew and philosophy. For some years, too, he was physician to David of Burgundy, Bishop of Utrecht, whom he cured of gout by making him take baths of warm milk. The Bishop rewarded him by shielding him from the attacks of the Dominicans, who were incensed by his bold criticisms of Aquinas; and when age brought the desire for rest, the Bishop set him over a house of nuns at Groningen, and bought him the right to visit Mount St. Agnes whenever he liked, by paying for the board and lodging of this welcome guest.
Wessel's last years were happily spent. He was the acknowledged leader of his society, and he divided his time between Mount St. Agnes and the sisters at Groningen, with occasional visits to Adwert. There he set about reviving the Abbey schools, one elementary, within its walls, the other more advanced, in a village near by; and Abbot Rees warmly supported him. Would-be pupils besought him to teach them Greek and Hebrew. Admiring friends came to hear him talk, and brought their sons to see this glory of their country—Lux mundi, as he was called. Some fragments of his conversation have been preserved, the unquestioned judgements which his hearers loyally received. Of the Schoolmen he was contemptuous, with their honorific titles: 'doctor angelic, doctor seraphic, doctor subtle, doctor irrefragable.' 'Was Thomas (Aquinas) a doctor? So am I. Thomas scarcely knew Latin, and that was his only tongue: I have a fair knowledge of the three languages. Thomas saw Aristotle only as a phantom: I have read him in Greece in his own words.' To Ostendorp, then a young man, but afterwards to become head master of Deventer school, he gave the counsel: 'Read the ancients, sacred and profane: modern doctors, with their robes and distinctions, will soon be drummed out of town.' At Mount St. Agnes once he was asked why he never used rosary nor book of hours. 'I try', he replied, 'to pray always. I say the Lord's Prayer once every day. Said once a year in the right spirit it would have more weight than all these vain repetitions.'
He loved to read aloud to the brethren on Sunday evenings; his favourite passage being John xiii-xviii, the discourse at the Last Supper. As he grew older, he sometimes stumbled over his words. He was not an imposing figure, with his eyes somewhat a-squint and his slight limp; and sometimes the younger monks fell into a titter, irreverent souls, to hear him so eager in his reading and so unconscious. It was not his eyesight that was at fault: to the end he could read the smallest hand without any glasses, like his great namesake, John Wesley, whom a German traveller noticed on the packet-boat between Flushing and London reading the fine print of the Elzevir Virgil, with his eyes unaided, though at an advanced age.
On his death-bed Wessel was assailed with scepticism, and began to doubt about the truth of the Christian religion. But the cloud was of short duration. That supreme moment of revelation, which comes to every man once, is no time for fear. Patient hope cast out questioning, and he passed through the deep waters with his eyes on the Cross which had been his guide through the life that was ending.
Of Rudolph Agricola we know more than of the others; his striking personality, it seems, moved many of his friends to put on record their impressions of him. One of the best of these sketches is by Goswin of Halen († 1530), who had been Wessel's servant at Groningen, and had frequently met Agricola. Rudolph's father, Henry Huusman, was the parish priest of Baflo, a village four hours to the north of Groningen; his mother being a young woman of the place, who subsequently married a local carrier. On 17 Feb. 1444 the priest was elected to be warden of a college of nuns at Siloe, close to Groningen, and in the same hour a messenger came running to him from Baflo, claiming the reward of good news and announcing the birth of a son. 'Good,' said the new warden; 'this is an auspicious day, for it has twice made me father.'
From the moment he could walk, the boy was passionately fond of music; the sound of church bells would bring him toddling out into the street, or the thrummings of the blind beggars as they went from house to house playing for alms; and he would follow strolling pipers out of the gates into the country, and only be driven back by a show of violence. When he was taken to church, all through the mass his eyes were riveted upon the organ and its bellows; and as he grew older he made himself a syrinx with eight or nine pipes out of willow-bark. He was taught to ride on horseback, and early became adept in pole-jumping whilst in the saddle, an art which the Frieslanders of that age had evolved to help their horses across the broad rhines of their country. In 1456, when he was just 12, he matriculated at Erfurt, and in May 1462 at Cologne. But the course of his education is not clear, and though it is known that he reached the M.A. at Louvain, the date of this degree is not certain. He is also said to have been at the University of Paris.
