Saints Mamas and James (A fragment)

Saints Mamas and James (A fragment), painted around 1457 and now in the Royal Collection, is a fragment from Pesellino's Trinity altarpiece—a predella panel or subsidiary element depicting two saints important to the commission's patron or location. Saint Mamas was an early Christian martyr particularly venerated in Cyprus and Greece; Saint James the Apostle was among the most widely venerated saints in Western Christianity. The fragment's presence in the Royal Collection documents the dispersal of the altarpiece across multiple collections following its dismemberment at some point after its creation.

Saints in Renaissance altarpiece panels typically stand or sit in three-quarter pose against a gold ground or architectural setting, identified by their attributes. Pesellino renders his saints with the delicate facial drawing and refined colour that characterise his work, each figure given individual physiognomy while conforming to the altarpiece's overall formal language.
