Thanks to his profession of notary Ser Piero, Leonardo's father, had close ties and friendships with the most prominent families in Florence, and not there alone (think, for instance, of the Bentivoglio, Lords of Bologna). He also worked for many civil and religious institutes, such as the monasteries of San Pier Martire, of San Donato a Scopeto and of the Santissima Annunziata. In the monasteries and palaces of Florence, Leonardo had various opportunities to accede to material for study and to receive commissions for paintings, as well as some assignments as consultant and designer.
