Sano di Pietro or Ansano di Pietro di Mencio (1406–1481) was an Italian painter of the Sienese school of painting. His career spanned from the end of the Trecento period into the Quattrocento period. His contemporaries included Giovanni di Paolo and Sassetta.
Sano was born in 1406. His name enters the roll of painters in 1428 where it remained until his death in 1481. In addition to his own painting and overseeing the pupils and assistants in his workshop, he was also part of the civic fabric of Siena. There are city records showing his participation. In 1431 and 1442 he was the leader of the San Donato district of Siena (1). Sano was also employed as an arbitrator; in 1475 he was called upon to settle a dispute between fellow painters Neroccio di Bartolommeo and Francesco di Giorgio Martini (2).
It was, however, as a painter that he made his living. The workshop he ran produced huge number of artworks. Sano himself is quite interesting. He wasn't merely a painter of altar pieces. He also produced frescoes, miniatures, and book bindings. Book bindings are exquisite little paintings that went on the spine of a book. After a long and successful career Sano died in 1481. His death notice read;
In the century before Sano's birth the Sienese school of painting had risen as a rival to that of the Florentines. The styles of the two schools were markedly different. Florence was said to be the more realistic of the two while Siena was said to be more fanciful. In fact the inscription above the Camopilla Gate leading into the city says;
Sienese painting was said to personify dreams. This can be seen in the hallmarks of the style of the Sienese School. Above all, the Sienese painters were known for their vibrant colors. They routinely used hues never seen in paintings before and rarely seen outside the city. They employed a richness of detail that can be quite unsettling for the first time viewer. The draperies of the clothing are elegant and numerous, but it is the patterns of the fabrics and the details on the necklines that can leave the viewer breathless. The paintings are at once sumptuous yet ethereal. This lightness of being displayed in the figures and even the landscapes themselves is the final hallmark of a painting from the Sienese School.
In the 15th century in Siena as elsewhere in Italy and Europe the successful painter had his own workshop. In his workshop he oversaw assistants and pupils that helped him finish the commissions the painter had received. It is indicative of Sano's success that over 270 of his works survive. It is one of the paradoxes about di Pietro that because he was so successful he is often overlooked. Many of his critics say that too many of his paintings resemble each other. It is important to remember that the painter produced what the customer asked for, not what he might paint for himself.The viewer must also take note of the fact that many of these works were not produced by Sano alone. In his A History of Sienese Painting George Edgall writes:
