philosophy, which is filled by competition, falling vacant, I took my doctor’s degree, presented myself for the said competition, was admitted and approved, and lectured in that city two years continuously on the text of Aristotle’s _De Anima_ and other philosophical works. Then, on account of the Civil Wars, I quitted and went to Paris, where, in order to make myself known, and to give proof of myself, I undertook an ‘extraordinary’ lectureship, and read thirty lectures, choosing for subject Thirty Divine Attributes, taken from the first part of St. Thomas. Later, being requested to accept an ‘ordinary’ lectureship, I would not, because public lecturers in that city go generally to mass and the other divine offices, and I have always avoided this, knowing that I was excommunicated because I had quitted my order and habit; and although I had that ‘ordinary’ lectureship at Toulouse, I was not forced to go to mass, as I should have been at Paris. But conducting the ‘extraordinary’ there, I acquired such a name that the king, Henry III, sent for me, and wished to know whether my memory was natural or due to magic art. I satisfied him, both by what I said, and proved to him, that it was not by magic art, but by science. After this I published a work on the memory, under the title _De Umbris Idearum_, which I dedicated to his Majesty,--on which occasion he made me ‘lecturer extraordinary,’ with a pension; and I continued to read in that city perhaps five years, when, on account of the tumults which arose, I took my leave, and with letters from the king himself I went into England to reside with his ambassador, Michael de Castelnau. In his house I lived as a gentleman. I stayed in England two years and a half, and when the ambassador returned to France I accompanied him to Paris, where I remained another year. Having quitted Paris on account of the tumults, I betook myself to Germany, stopping first at Mayence, an archiepiscopal city, for twelve days. Finding neither here nor at Würzburg, a town a little way off, any entertainment, I went to Wittenberg, in Saxony, where I found two factions,--one of philosophers, who were Calvinists, the other of theologians, who were Lutherans. Among the latter was Alberigo Gentile, whom I had known in England, a law-professor, who befriended me and introduced me to read lectures on the _Organon_ of Aristotle; which I did, with other lectures in philosophy, for two years. At that time, the son of the old Duke having succeeded his father, who was a Lutheran, and the son being a Calvinist, he began to favor the party opposed to those who favored me; so I departed, and went to Prague, and stayed six months. Whilst there, I published a book on geometry, which I presented to the Emperor, from whom I had a gift of three hundred thalers. With this money, having quitted Prague, I spent a year at the Julian Academy in Brunswick; and the death of the Duke[28] happening at that time, I
