Agnolo Ambrogini, commonly known as Angelo Poliziano or simply Poliziano, anglicized as Politian, was an Italian classical scholar and poet of the Florentine Renaissance. His scholarship was instrumental in the divergence of Renaissance Latin from medieval norms and for developments in philology. His nickname Poliziano, by which he is chiefly identified to the present day, was derived from the Latin name of his birthplace, Montepulciano.
