Leonardo di Giovanni Tolosani
A notary and lawyer of Colle Val d’Elsa, he was a friend and collaborator of Vespasiano da Bisticci. He obtained the title of notary in 1456-1457, obtained a doctorate in Pisa for canon law and civil law in 1481, and was employed at the Florentine chancellery from 1483 to 1491. The Florence State Archives preserve 19 volumes of protocols written under his name; the documents date between 1457 and 1497. His son was the Dominican mathematician Giovanni Maria de’ Tolosani (c. 1472-1549; see Marzi, La questione della riforma, pp. 130-131). The dated manuscripts that he undersigned date back to the years 1456 to 1459; the initials used in these signatures include «L.J.», «L. Io.» and «Le. Io. de Colle». He is likely the «Lionardo da Colle» who undersigns the ms. Urb. lat. 899 on f. 124v (not registered in Bénédictins du Bouveret, Colophons de manuscrits occidentaux).
