He wrote copious texts: about the best and most virtuous ways to write, to paint, to sculpt, to run a family, to ride a horse, to walk down the street, and to commission, design and construct buildings, always with reference to classical precedents. In his thirties he wrote an anonymous autobiography, attributing to himself phenomenal physical, intellectual and moral feats, describing himself as the perfect Renaissance man. Whatever the truth of these claims, he could legitimately boast of writing his epoch's definitive theoretical books on both painting and architecture.
