Nicholas' father was Ulrich Ellenbog, a physician of Memmingen, who graduated as Doctor of Medicine from Pavia in 1459, and became first Reader in Medicine at Ingolstadt. The letters introduce us to most of his children. One son, Onofrius, went for a soldier, became attached to Maximilian's train, and received a knighthood; another, Ulrich, became M.D. at Siena, but died immediately afterwards; another, John, became a parish priest. Of the daughters three remained in the world; one, Elizabeth, married; another, Cunigunde, died of plague caught in nursing some nuns. The fourth daughter, Barbara, at the age of nine entered the convent of Heppach, and lived there forty-one years, rising to be Prioress and then Abbess. We shall hear of her again.

Nicholas Ellenbog, 1480 or 1481-1543, was the third son. After five years at Heidelberg, 1497-1502, in which he met Wimpfeling and was fellow-student, though a year senior, to Oecolampadius, he went off to Cracow, the Polish university, which was then so flourishing as to attract students from the west. Schurer, for example, the Strasburg printer, was M.A. of Cracow in 1494; and some idea of the condition of learning there may be gained from a book-seller's letter to Aldus from Cracow, December 1505, ordering 100 copies of Constantine Lascaris' Greek grammar. For some months Ellenbog heard lectures there on astronomy, which remained a favourite subject with him throughout his life. Then an impulse came to him to follow his father's footsteps in medicine, and at the advice of friends he went back across half Europe to Montpellier, which from its earliest days had been famous for its medical faculty. In the long vacation of 1502 he spent two months with a friend in the château of a nobleman among the Gascon hills, and on their return journey they stayed for a fortnight in a house of Dominican nuns. The sisters were strict in their observances, and gave a good pattern of the unworldly life, which attracted Ellenbog strongly. In 1503 he went home for the long vacation to Memmingen. On the way he was taken by the plague, and with difficulty dragged himself in to Ravensburg. For three months he lay ill, and death came very close. As its unearthly glow irradiated the world around him, reversing its light and shade, the visions of the nunnery recurred. He vowed that if his life were still his to give, it should be given to God's service; and on recovering he entered Ottobeuren.

In his noviciate year he was under the guidance of a kind and sympathetic novice-master, who allowed him to study quietly in his cell to his heart's content; and during this period he composed what he calls an epitome or breviary of Plato. Its precise character he does not specify, but its second title suggests that it may have been a collection of extracts from Plato: not from the Greek, for he had little acquaintance with that yet, but presumably from such of Plato's works as had been translated into Latin. On Ascension Day, 1504, which appears from other indications to mean 15 August, he made his profession, and in September 1505 he went to Augsburg to be ordained as sub-deacon. Writing to a friend to give such news as he had gathered on this outing, he tells a story to convict himself of hasty judgement. During the ordination service he noticed that one of the candidates, a bold-eyed fellow who had been at several universities, and had been Rector at Siena, let his gaze wander over the ladies who had come to see the ceremony, instead of keeping it fixed on the altar. Ellenbog censured him in his mind, but later he noticed that as the man kneeled before the bishop with folded hands to receive unction, his eyes were filled with tears of repentance—others perhaps would have called it merely emotion.

On his way back to Ottobeuren, Ellenbog arrived at a village, where he had counted on a night's rest, only to find it crowded with a wedding-party; the followers of the bridegroom, who were escorting him to the marriage on the morrow, a Sunday. It was with great difficulty that he found shelter, in the house of a cobbler, who let him sleep with his family in the straw; but it was so uncomfortable that before dawn he crept out and started on his way under the moon. In the half light he missed the road and found himself at the bride's castle; where he learnt that her sister was just dead and the wedding postponed. As he passed in that evening through the abbey-gate, there was thankfulness in his heart that he was back out of the world and its petty disappointments.

On Low Sunday, 1506, he was ordained priest at Ottobeuren, and celebrated his first mass. Some of his letters are to friends inviting them to be present, and adjuring them to come empty-handed, without the customary gifts. In these early years there was ample leisure for study. In 1505 he began Greek, and in 1508 Hebrew. He speaks of reading Aeneas Sylvius, Pico della Mirandola, Cyprian, Diogenes Laertius, Ambrose, Chrysostom, Dionysius the Areopagite. He went on with his astronomy, and cast horoscopes for his friends. Binding books was one of his occupations; and in 1509, when a press was set up in the monastery, he lent a hand in the printing. He was very fortunate in his abbot, Leonard Widemann, who had been Steward when he entered Ottobeuren, but was elected Abbot in 1508, and outlived him by three years, dying in 1546. Widemann called upon him for service. Immediately on election he made him Prior—at 28—and only released him from this office after four years, to make him, though infinitely reluctant, serve ten years more as Steward.

But if the Abbot knew how to exact compliance, he knew also how to reward. He gave Ellenbog every assistance in his studies, allowed him to write hither and thither for books, made continual efforts to procure him first a Hebrew and then a Greek Bible, wrote to Reuchlin to find him a converted Jew as Hebrew teacher, and in 1516 built him a new library; for which Ellenbog writes to a friend asking for verses to put under the paintings of the Doctors of the Church, which are to adorn the walls. As results of his studies we hear of him correcting the abbey service-books, where for stauros, a scribe with no Greek had written scayros, and explaining to the Abbot mistaken interpretations in the passages read aloud in the refectory during meals. One of these, in a book written by some one who had recently been canonized—some mediaeval doctor—illustrates the learning of the day; deriving γαστργια, gluttony, from castrum and mergo, 'quod gula mergat castrum mentis,' because gluttony drowns the seat of reason.

Of Ellenbog's official duties occasional mention is made in his letters. As Steward he has to visit the tenants of the monastery; in the autumn he journeys about the country buying wine. We hear of him at Westerhaim, on the river Iller, settling a dispute among the fishermen. On one of his journeys to fetch wine from Constance, at the hospice there he fell in with a man who could fire balls out of a machine by means of nitre, and who boasted that he could demolish with this weapon a certain castle in the neighbourhood. Over supper they began to argue, the artillerist maintaining that nitre was cold, and that the explosion which discharged the balls was caused by the contrariety between nitre and sulphur; Ellenbog contending that nitre was hot, and supporting this view by scraps remembered from his father's scientific conversation.

The general life of the Abbey is also reflected. Ottobeuren lay on one of the routes to Italy, and so they had plenty of visitors bringing news from regions far off: a Carthusian, who had been in Ireland and seen St. Patrick's cave; a party of Hungarian acrobats with dancing bears; a young Cretan, John Bondius, who had seen the labyrinth of Minos, but all walled up to prevent men from straying into it and being lost. A great impression he made, when he dined with the Abbot; he was so learned and polished, and spoke Latin so well for a Greek. In 1514 Pellican, the Franciscan Visitor, passed on his way south, and had a talk with Ellenbog, which was all too short, about Hebrew learning. Next year came Eck, the theologian, the future champion of orthodoxy, returning from Rome. Eck's mother and sisters were living under the protection of the abbey—it is not clear whether they were merely tenants, or whether they were occupying lay quarters within its walls, as did Fernand's at St. Germain's in Paris. At any rate, Eck came and made himself agreeable. He preached twice before the brethren; and when he left, he promised to send them the latest news from America. In 1511 a copy of Vespucci's narrative of his voyage had been lent to the monastery, and had been read with great interest.

A grave question arose whether the new races discovered in the West were to be accounted as saved or damned. Ellenbog quotes Faber Stapulensis' statement that nothing could be more bestial than the condition of the Indians whom da Gama had discovered in 1498 in Calicut, Cannanore, and Ceylon; it was to be feared that the Indians of the West were no better. In writing to Ellenbog six months later to say that he had no clear opinions on the question, Eck uses an interesting expression: 'To ask what I think is like looking for Arthur and his Britons.'[4] The reference is to the Arthurian legend and the long-expected, never-fulfilled, return of the great king; but the humanists usually leave the whole field of mediaeval romance severely alone.

One September morning, when the dew was still heavy, Ellenbog went out with some brethren to gather apples. At the top of the orchard[5] one of them called out that he had found 'a star'. It was a damp white deposit on the grass, clammy and quivering, cold to the touch, very sticky, with long tenacious filaments. Ellenbog had never seen anything like it, but he found out that the peasants and the shepherds believed such things to be droppings from shooting stars,[6] if not actually fallen stars, and that they were thought to be a cure for cancer. His letter describing it is to ask the opinion of a friend who was a doctor, that is to say, the scientist of the age.
