シエナ大聖堂
Of Duccio's surviving works, only two can be definitively dated. Both were major public commissions: the "Rucellai Madonna" (Galleria degli Uffizi), commissioned in April 1285 by the Compagnia del Laudesi di Maria Vergine for a chapel in Santa Maria Novella in Florence; and the Maestà commissioned for the high altar of Siena Cathedral in 1308, which Duccio completed by June 1311.
