born 0441; 1403, Siena, Republic of Siena
died 1482, Siena
Italian painter active in Siena.
A prolific artist, he produced his most characteristic works from the 1440s, notably the monumental altarpiece The Presentation of Christ in the Temple (144749), 12 scenes from the life of St. John the Baptist, and a Madonna (1463) altarpiece in Pienza Cathedral. He also painted countless other religious panels. His tormented spirituality and expressionistic style were little appreciated until his reputation was revived in the 20th century.
