Italian, Perhaps Tuscan, 14th century

The present standing figure of Aristotle, with his deeply undercut hair, protruding brow, distinctive, elongated eyes and illogical position of the turned head, resembles the work of the Italian Gothic sculptor Giovanni Pisano (1248-1315) and his pupil Tino di Camaino (c. 1280-c. 1337), who worked together on the façades of the Siena and Pisa cathedrals.  

The general facial type and the attenuated fingers and broad palm in the present sculpture are also comparable to those found on figures by Giovanni di Agostino (c. 1310–c. 1370), who also produced ecclesiastical sculpture for the Siena cathedral, see the hands of the marble figures of St Francis and Elizabeth of Hungary by Di Agostino now in the Pinacoteca Nazionale, Siena.
