[23] The biographers of Signorelli, following the lead of Vasari, have dwelt much on his friendship with contemporary princes—the Baglioni, Vitelli, etc.; till we have grown to think of him rather as a silk-clad courtier than a hard-working burgher and painter. It may well be that, like Leonardo, he combined work with luxury, but the evidence is of too slight a nature to allow us to consider that side of his life, if it really existed. Of his friendship with Lorenzo dei Medici, however, there is more proof, since he painted for him, and was evidently influenced by his classic tastes, as several of his pictures show.
