Christ appears in a transfigured state to the apostles Peter, John & James. Either side of Christ are Moses (left) & the prophet Elijah (right). This panel was part of the back predella of Duccio's ' Maestà', & was immediately to the right of ' Jesus opens the Eyes of a Man born Blind'. Another panel from the ' Maestà' is in the collection, ' The Annunciation'. The ' Maestà' was a monumental double-sided altarpiece ceremoniously delivered to Siena Cathedral in June 1311, & placed on the high altar. At the time it was the richest & most complex altarpiece in Christendom, but it was dismembered in 1771, & although most of it is in the Cathedral Museum in Siena, several predella panels & pinnacles are dispersed in collections throughout the world. The front of the altarpiece shows the Virgin & Child enthroned with saints & apostles, the predella depicts Christ's childhood, & the pinnacles, the last days of the Virgin. On the reverse the narrative runs from Christ's earthly ministry through his Passion to his latter day appearances.
