While working on his translations of the Zohar and the Bahir in Venice in 1547, Postel became the confessor of Mother Zuana, an elderly woman who was responsible for the kitchen of the hospital of San Giovanni e Paolo. Zuana confessed to experiencing divine visions, which inspired Postel to believe that she was a prophet, that he was her spiritual son, and that he was destined to be the unifier of the world's religions. When he returned from his second journey to the East, he dedicated two works to her memory: "Les Très Merveilleuses Victoire des Femmes du Nouveau Monde" and "La Vergine Venetiana".
