In 1469 Leonardo was not listed among the «mouths» in the family of his father, in the Commune of Vinci. For this reason, it was commonly believed that Leonardo had moved to Florence in that year. In reality, it is probable that his training in art began even earlier, and that he had lived in Florence much before this date. The last certain information shows that Leonardo lived in Palazzo Martelli in 1508. The last of his projects for Florence dates instead from 1515, when he worked on the Medicean quarter.
