Mino di Graziano (1289âÂÂ1323) was an Italian painter, active in Siena. He is said to have painted frescoes in the Sala del Consiglio of the Palazzo Pubblico of Siena. On 4 December 1310, di Graziano and two other painters (Sebastiano Rama and Mino Prete) were summoned before a judge for non-payment of rent for a house. The three painters were probably collaborating and using the house as a workshop.
