Raymund afterwards became abbot of the convent. But it was his predecessor, Gerald, who had received the boy Gerbert, and was still to do something of moment in directing his career. A certain duke of the Spanish March came on a pilgrimage to Aurillac; and Gerald besought him to take Gerbert back with him to Spain for such further instruction as the convent did not afford. The duke departed, taking Gerbert, and placed him under the tuition of the Bishop of Vich, a town near Barcelona. Here he studied mathematics. The tradition that he travelled through Spain and learned from the Arabs lacks probability. But in the course of time the duke and bishop set forth to pray for sundry material objects at the fountainhead of Catholicism, and took their _protégé_ with them to Rome. In Rome, Gerbert’s destiny advanced apace. His patrons, doubtless proud of their young scholar, introduced him to the Pope, John XIII., who also was impressed by Gerbert’s personality and learning. John told his own protector, the great Otto, and informed him of Gerbert’s ability to teach mathematics; and the two kept Gerbert in Rome, when the Spanish duke and bishop returned to their country. Gerbert began to teach, and either at this time or later had among his pupils the young Augustus, Otto II. But he was more anxious to study logic than to teach mathematics, even under imperial favour. He persuaded the old emperor to let him go to Rheims with a certain archdeacon from that place, who was skilled in the science which he lacked. The emperor dismissed him, with a liberal hand. In his new home Gerbert rapidly mastered logic, and impressed all with his genius. He won the love of the archbishop, Adalberon, who shortly set the now triply accomplished scholar at the head of the episcopal school. Gerbert’s education was complete, in letters, in mathematics including music, and in logic. Thenceforth for ten years (972-982), the happiest of his life, he studied and also taught the whole range of academic knowledge. Fortune, not altogether kind, bestowed on Gerbert the favour of three emperors. The graciousness of the first Otto had enabled him to proceed to Rheims. The second Otto listened to his teaching, admired the teacher, and early in the year 983 made him Abbot and Count of Bobbio. Long afterwards the third Otto made him Archbishop of Ravenna, and then pope.
