 In 1550 Vasari was himself painting in the villa, but he very possibly visited it before that.But in 1975 it emerged that, unlike the "Primavera", the "Birth" is not in the inventory, apparently complete, made in 1499 of the works of art belonging to Lorenzo di Pierfrancesco's branch of the family.Ronald Lightbown concludes that it only came to be owned by the Medici after that.
