Drawings from 1470 to 1489 – from 1490 to 1519

In this codex, are collected all the autograph drawings that were made from 1470 to 1489.
The main part of the works refers to  preliminary studies about pictures which were made later. For example the two “Annunciazione”, “L’Adorazione dei Magi”, “La Vergine delle Rocce”, “La Madonna del Fiore”. Some studies were used to make works which had been realized by other painters  for example (Madonna Litta) or had never been painted for  example (  Madonna del Gatto, Madonna della coppa di frutta). The studies of military art and the Moral Allegories are a lot.
