Possibly this stay in Venice has something to do with the solution of a question which has been frequently mooted and was solemnly discussed at a congress of physicians at San Francisco as late as 1900, namely, why did Vesalius, the great anatomist, go to the Holy Land? The usual supposition is that it was to perform a penance enjoined by the Inquisition in consequence of some alleged heretical utterances by the illustrious scientist. However, Sir Michael Foster of the University of Cambridge, who was the principal speaker at the Congress, offered another explanation. "It is probable," he said, "that while pursuing his studies in the hospitals of Venice, Vesalius often conversed with another young man who was there at the time and who was known as Ignatius Loyola." Such a meeting may, indeed, have occurred, for Ignatius haunted the hospitals, and his keen eye would have discerned the merit of Vesalius, who was a sincerely pious man. Hence, it is not at all unlikely that the young physician may have made the "Spiritual Exercises" under the direction of Ignatius, and that his journey to the Holy Land was the result of his intercourse with the group of brilliant young students, who just then had no other object in life but to convert the Turks. On the journey to Rome Ignatius went ahead with Faber and Laínez, and it was then that he had the vision of Christ carrying the cross, and heard the promise: "Ego vobis Romæ propitius ero" (I will be propitious to you in Rome.) They were received affectionately and trustingly by the Pope, who sent Laínez and Faber to teach in the Sapienza, one lecturing on holy scripture and the other on scholastic theology; while Ignatius gave the "Spiritual Exercises" wherever and whenever the opportunity presented itself. When the other four arrived, they were immediately employed in various parts of Rome in works of charity and zeal.
