Guido of Siena

Guido of Siena, was an Italian painter, active during the 13th-century in Siena, and painting in an Italo-Byzantine style.

The name Guido is known from the large panel in the church of San Domenico, Siena of the Virgin and Child Enthroned. The rhymed Latin inscription gives the painter's name as Guido de Senis, with the date 1221. However, this date cannot relate to the painting of the panel, which is usually dated on the basis of style to the 1270s. The faces of the Virgin and Child were scraped and repainted in the early 14th century in the manner of Duccio and so are not representative of Guido's original.

A dossal featuring the Virgin and Child with four saints (accession No. 7) in the Siena Pinacoteca has an identical inscription, but unfortunately the name before "de Senis" has been cut off. It is very often assumed that the missing name is Guido, and gives us some indication of the original appearance of the Madonna at San Domenico.

Beyond this, little is known of Guido da Siena and his place in Sienese painting before Duccio.
