CAMAINO DI CRESCENTINO
(b. ca. 1260, Siena, d. ca. 1337, Siena)
The Baptistery in Siena was founded in 1316, but left unfinished in the third quarter of the fourteenth century. A complete design in colour for the façade by an unknown author working c. 1339 survived in the Museo dell'Opera del Duomo, Siena.
