[Stefano di Giovanni di Consolo]
(b Siena or Cortona, c. 1400; d Siena, April 1, 1450).
Italian painter and illuminator. He was the most original painter in Siena in the 15th century. Working within the Sienese tradition, he introduced elements derived from the decorative Gothic style and the realism of such contemporary Florentine innovators as Masaccio. Most of his surviving works are panel pictures, notably those from the altarpiece painted for S Francesco, Borgo San Sepolcro.
The name Sassetta appears to have been associated with him, mistakenly, only since the 18th century (Pecci, 1752), but it is generally used. He was the son of Giovanni di Consolo of Cortona (Bacci, 1936) and is firmly documented first in 1426 in Siena but was probably active there earlier. His influences included Taddeo di Bartolo, Martino di Bartolommeo (fl 1389; d c. 1435), Benedetto di Bindo, Gregorio di Cecco and other artists who were links between the great Sienese painters of the early 14th century (Simone Martini, Ambrogio Lorenzetti and Pietro Lorenzetti) and the art of the 15th-century Renaissance....
