 He left in 1511 to go to school, returning to St. Donatian in 1513 as a cleric, where he stayed until 1515.Until recently, nothing was known of his activities for the next four years, but in 1989 some records from the Vatican archives were published that showed that he spent this time in Rome.One of these documents, dated April 1518, gave his age as 24, which gives a birth date of 1493 or 1494.
