Description: This artist was probably trained in the workshop of Sassetta before starting his prolific career in the area in and around Siena. In the 1440s, he is also documented to have worked in the field of illuminated manuscripts. His painting shows aspects of compositional repetition and formal unity as well as a component of spirituality and of conscious devotional choice. The six panels originally formed the predella of an altarpiece or a private devotional painting, and the original frame is still preserved. The panel, dating from around 1450, organizes the figures by placing them within Gothic framing, unusual for Sano, but the artist was probably drawing on prototypes of fourteenth-century local tradition. The figure of St. John the Baptist, on the far right, is more recent.
