Whilst still presiding over his school, Gerbert produced several treatises on astronomy, mathematics, and geometry; on the formation of the astrolabe, the quadrant, and the sphere, as well as on rhetoric and logic. The monk Ditmar tells us that when at Magdeburg with his old pupil, Otho III., he made a clock, regulating it according to the movement of the polar star, which he observed through a kind of tube. Another writer speaks of certain hydraulic organs which he constructed, in which the wind and necessary movements were introduced by means of boiling water: and these obscure notices seem to indicate that wheeled clocks, the telescope, and the power of steam, were known by Gerbert fully three centuries before what has been considered their earliest discovery by our own Roger Bacon. Gerbert did not teach at Rheims alone. Crossing the Alps, he passed through most of the towns of Northern Italy, then subject to his great patron, Otho I. In 970 he also visited Rome in company with the bishop Adalberon, and at Pavia met the emperor, together with the celebrated Saxon, Otheric, whom we have seen filling the office of scholasticus in the episcopal school of Magdeburg. Otheric had up to that time enjoyed the reputation of being the greatest scholar of his age, and perhaps regarded himself somewhat in the light of a literary dictator. In the course of the previous year he had felt no little uneasiness at the daily increasing renown of the French professor, and had despatched one of his own Saxon pupils to Rheims to bring him an exact account of Gerbert’s method of dividing the sciences. The Saxon made an unsatisfactory report. It was Gerbert’s custom to represent physics and mathematics as equal and independent sciences. But Otheric’s disciple, whose head was none of the clearest, made him teach that physics were subordinate to mathematics, as the species to the genus. On this, Otheric decided that he knew nothing of philosophy, and proceeding to the court of the emperor, Otho I., he spoke to that effect before an assembly of learned men. Otho, who was himself passionately fond of these studies, was not satisfied, and resolved to sift the matter to the bottom. He therefore seized the occasion of Gerbert’s presence at Pavia to inaugurate a grand scientific tournament, and invited all the savants of his empire to witness the dispute between the first scholar of France and the first scholar of Germany. He himself presided at the conference, and opened it with a brief allocution of his own, in which he very clearly explained the question in dispute. Then Otheric began his attack, first in words, and then in writing. The conference lasted the whole day, and Gerbert, who cited the authorities of Plato, Porphyry, and Boëthius, was still speaking in reply when the emperor gave the signal for the conclusion of the debate. Gerbert’s fame never appeared more illustrious, and he returned to France loaded with magnificent presents.
His after career was full of troubles; but in 990 the influence of his imperial pupil, Otho III., obtained his election to the see of Ravenna, and nine years later to the Apostolic chair. It was a great day in the annals of learning when the philosopher Gerbert became Pope Sylvester II., and one which brought no small satisfaction to the hearts of his pupils. Half the prelates and princes of Europe gloried in having called him master, and most of them did him credit. Among them were our own St. Ethelwold; Fulbert of Chartres, the oracle of his own time; and Robert, king of France, the son of Hugh Capet, and the most religious and learned sovereign of the age. King Robert was well skilled in all the humane sciences; but the love of music, which he had imbibed from his master, amounted to a passion. Even after his accession to the throne, he devoted no small part of his time to composing anthems, and motetts, to the indignation of his queen, Constance, who asked him once, if he must compose, to compose something upon her. Robert sat down and produced the hymn O Constantia martyrum! and the queen, who fortunately understood nothing of Latin, was quite satisfied, imagining that her own perfections formed the subject of the poem. He often assisted in the choir of St. Denis, dressed in his royal robes, singing with the monks and directing the chant. Robert is said by his biographer always to have had a book in his hand, and to have carried the Psalter in his bosom. He once visited Rome, and during the Pope’s mass laid on the altar, as his offering, a folded packet, which from its great size and weight the attendants concluded to be gold. On opening it, however, they found it to be only a fair copy of his antiphon, Cornelius Centurio. Admiring the writing and the musical notes, as well as the genius and piety of the author, the Pope desired that thenceforward this antiphon should always be sung on the festival of St. Peter, of whose Office it still continues to form a part.
Not less learned was Gerbert’s other royal pupil, Otho of Germany, surnamed “the Wonder of the World,” whose early death prevented his making as much use of his advantages of education as was confidently expected by all who knew the singular excellence to which he had attained. Besides these illustrious disciples, Gerbert had others of every rank and calling. The great St. Ethelwold is said by many writers to have studied under him for a time, and the rapid development in England and elsewhere of mathematical studies at this period must certainly be assigned to the impulse given them by the teaching of the master of Rheims. His genius was emphatically scientific, and this is the character which we find impressed on the learning of most of his followers. Thus Richer, the monk from whose history most of the above particulars have been taken, was more particularly skilled in the science of medicine. As an instance of the solicitude which monks of the tenth century displayed in the pursuit of knowledge, I may refer to the very curious account which he gives us of the perilous journey he once undertook, for the purpose of perusing a single book on his favourite science. “It was in the year 951,” says Richer, “when my mind, being much and deeply engaged in the study of literature, I had long entertained an ardent desire of having the opportunity of learning the logic of Hippocrates of Cos. One day I chanced to meet in the city of Rheims a horseman coming from Chartres. Asking him who he was, and wherefore he had come hither, he replied that he was a messenger from Heribrand, a clerk of Chartres, and that he wished to speak to one Richer, a monk of St. Rémi. As soon as I heard my friend’s name, and the subject of his message, I told the stranger that I was the person he was in quest of; whereupon, having embraced one another, he gave me a letter, which I found was an invitation to come to Chartres and peruse the ‘Aphorisms.’ I was much rejoiced at this; wherefore, taking a servant with me, I determined on accompanying the horseman back to Chartres. The only assistance I received from my abbot was a loan of one of the draft horses. Without money, or even a change of clothes, and destitute of every necessary for the journey, I set out and reached Orbais, where I was not only delighted with the conversation of the abbot, but greatly assisted by his noble gifts, so that next day I was able to get on as far as Meaux. On entering the woods, however, with my two companions, we were involved in several disasters; for, deceived by its wild and broken openings, on coming to a place where two ways met, we took the wrong turning, and were led six leagues out of our road.
“By the time we passed Château Thierry my cart-horse, which had at first seemed a sort of Bucephalus, began to lag on the road as lazily as if he had been a donkey. The sun had been sinking for some time, and the rain was falling fast. At this moment the horse, worn out with fatigue, sank under the lad who was riding him, and the poor beast expired, as though struck by lightning. This happened when we were about six miles from the city of Meaux. My agitation and anxiety at this disaster may be well conceived; the boy, quite inexperienced in such emergencies, lay helpless on the road, by the side of the dead horse. There lay the luggage also, with no one to carry it; the rain was pouring down from a dark and cloudy sky, and the sun was just on the horizon. By God’s goodness a prudent thought, however, suggested itself to my mind. I left the boy on the road with the baggage, telling him what he ought to say if questioned by travellers, urging him not to yield to any inclination to sleep. Then, accompanied by the horseman from Chartres, I set out for Meaux. There was scarcely light to see the bridge; and on examining it, a new misfortune presented itself. It was so broken, and had such enormous holes in it, that even by day it could hardly have been crossed in safety. The Chartres horseman, however, here showed himself a ready man. After vainly searching for a boat, he returned to the bridge, and, with the help of God, succeeded in getting the horses over it. In some places he covered the huge holes with his shield, so as to support the feet of the animals; in others he put the separated planks close together, and what with stooping, and what with holding himself erect, and now keeping the beasts together, and now separating from them, he contrived to get over in safety. It was a dreadful night, and all around was buried in darkness when I reached the church of St. Faro, where I was hospitably received by the monks, and refreshed with kind words and abundance of food. The horseman was at once sent back with other steeds, again passed the dangerous bridge, and proceeded to search for the poor boy, whom we had left on the road. It was the second watch of the night when he came up with him. He at once brought him to the city, but fearful of attempting a third time to cross the bridge they determined on passing the night in a poor cabin, and at break of day appeared at the gates of the monastery, half dead with hunger. Food was immediately given them, and corn and straw supplied to the horses.
“Leaving the dismounted boy with Abbot Augustin (of St. Faro), I hastened on to Chartres with the horseman, whence I sent back horses, who brought the lad back from Meaux. When he was come, and my mind was thus set at rest, I sat down at once to the earnest study of the ‘Aphorisms’ of Hippocrates, together with Master Heribrand, a man as much distinguished for his politeness as for his great learning. But as in these ‘Aphorisms’ I only learnt the premonitory symptoms of diseases, and as this knowledge did not satisfy me, I desired also to study another book showing the concordance between Hippocrates, Galen, and Suranus. This also I obtained from Heribrand, who was perfectly well skilled in the science to which he devoted his time. Indeed, there was nothing in medicine, pharmacy, botany, or surgery unknown to him.” Richer’s appreciation of his friend’s learning may possibly have been exaggerated; but who can fail to admire his perseverance in overcoming such difficulties as a journey then presented, with the simple view of increasing his stock of scientific knowledge by the perusal of one precious book?
Allusion has been made to the improvements introduced by Gerbert in the study of music. A little later a more important addition was made to the same science by Guy, a monk of Pomposa, commonly called Guy of Arezzo, from the city which gave him birth. He had been educated from the age of eight years in the monastery of Pomposa; and being well skilled in music, was employed in teaching the ecclesiastical chant to the children brought up in the house. But the immense difficulties of his task induced him to consider whether some method of facilitating the notation of music might not be devised. As yet, the sounds of the musical scale were only represented by the first seven letters of the alphabet, or by notes, as was the custom in the abbeys of Corby and St. Gall, which showed indeed the relative length and value of each tone, but did not render their succession sensible to the eye. After seeking for a long time for some easy and precise system, Guy one day recognised in the chant to which the hymn of St. John Baptist was ordinarily sung, an ascending diatonic scale, in which the first syllable of each line occupied one note: Ut queant laxis—Resonare fibris—Mira gestorum—Famuli tuorum,—Solve polluti—Labii reatum,—Sancte Ioannes. He applied himself to teach this chant to his pupils, and to render them familiar with the diatonic succession of the syllables, ut, re, mi, fa, sol, and la. Next, he arranged the notes on lines and intervals, and thus produced the musical staff with its proper clefs. By means of these improvements he found himself able, in a few months, to teach a child as much as a man, under the ancient system, would have had difficulty in learning in the course of many years. However, such a storm of jealousy arose against him on the score of his discovery, that he found himself obliged to leave the monastery; and accordingly, in 1024, he travelled to Rome, where Pope John XIX. warmly received both him and his newly-invented gamut.
“The Pope,” he says, “having received me kindly, conversed with me for a long time, asking many questions, and turning over the leaves of my antiphonarium, seemed to think it a sort of prodigy. He conned its rules, and would not rise from his seat till he had tried to learn a verse which he had never yet heard sung, and to his great astonishment found himself able to do it.” Guy was not allowed to leave Rome till he had promised to return the next winter, and give a regular course of musical instructions to the Pope and his clergy. The sunshine of Papal favour soon dissipated the storm, but the humble religious was no way puffed up by his triumph. He only rejoiced at being able to spread the knowledge of a discovery which would be useful to others. “The designs of Providence,” he writes, “are obscure, and falsehood is sometimes suffered to oppress the truth; God so ordering it lest, puffed up with self-confidence, we should suffer loss. For then only is what we do good and useful when we refer all we do to Him who made us. God inspiring me with the knowledge, I have made it known to as many as I could, to the end that if I, and those who have gone before me, have learnt the Cantus with extreme difficulty, those who come after me, doing so with greater facility, may pray for me and my fellow-labourers, that we may obtain eternal life and the remission of our sins.”
At the very time when Gerbert was astonishing the world by the marvels of his genius, a simple nun of Gandersheim had attained a degree of literary excellence, which is the more remarkable as it was exclusively acquired within the enclosure of her own convent. The foundation of this convent had taken place at the same time with that of New Corby, and its object had been specially to provide for the education of the Saxon ladies. Peculiar attention was therefore directed to maintaining its school in a due state of efficiency, and learned traditions were always kept up among the nuns. Having fallen into decay in the ninth century, it was restored by Count Lindolph, whose daughter, Hathmuda, became abbess in 856. Her life has been left, written by her brother Agius, or Egbert. Hathmuda was a great lover of letters. “From a child,” says her brother, “she cared nothing at all for fine clothes, head-dresses, ribbons, combs, earrings, necklaces, bracelets, handkerchiefs, girdles, and scents, the possession and wearing of which stirs up the ambition of so many women.” She preferred to pray and to study, and “the lessons to which others had to be forced by stripes she willingly applied herself to, giving herself up to them with indefatigable ardour.” When she became abbess she was most desirous to keep up those sacred studies for which the monastery had ever been so famous. “She insisted on the study of the Scriptures, and those who applied themselves to reading she greatly loved, but did not admit to equal familiarity such as herein showed themselves to be slothful.” Her cares were amply rewarded, and the school of Gandersheim produced a succession of excellent teachers, among whom was Hroswitha, the fourth abbess, who died in 906, and was the authoress of a treatise on logic, much esteemed among the learned of her own time.[144]
It is of a namesake of this fair logician that we are now about to speak, Hroswitha, the nun of Gandersheim, as she is called. She was born in the year 940, and was brought up in the convent school, where she studied Greek and Latin, the philosophy of Aristotle, and the other liberal arts. We are often told that expressions like these, however magnificent they look on paper, would dwindle into insignificance could we test their value by the real amount of learning which they represent. With regard to Hroswitha, however, the true nature of her erudition is not left to conjecture. She has left behind her writings which have attracted the favourable notice even of modern critics, who agree in declaring that the Latin poems of this obscure nun of the tenth century are marvels of classical taste and poetic genius. Besides a panegyric on the three Othos, she wrote eight poems on various religious subjects, some of them being taken from the life of our Lord, and some from the legends of the saints; and seven prose dramas in the style of Terence, being tales of holy women, and having for their subject the praise of chastity. While praising the delicacy of the sentiments and the correctness of the style, her critics observe that these dramas afford incidental evidence of her perfect familiarity with the sciences of music, astronomy, and dialectics, as then taught in the schools. In one of them she introduces a sort of apology for her own learning, which has a certain feminine grace about it, more charming than all her logic. It occurs in the drama of “Paphnutius,” where, after a philosophic discussion on the art of music, one of the disciples of the saint is made to ask him:
“Whence do you derive all this knowledge?” and he replies, “It is but a little drop that I have gathered from the ever-flowing sources of science; and now I desire to share it with you.”
