Marguerite de Navarre
Jean began his religious career as a young Dominican novice, in either their Convent in Condom or the one in Agen. From the beginning he showed outstanding talent as a public speaker. He was introduced to Queen Marguerite de Navarre, the sister of King Francis I of France, who often stayed in her chateau at Nérac, just north of Condom, and quickly became part of her entourage, abandoning his life as a Dominican friar.
