Relics of the cross upon which Christ died were the most prized of all relics, representing a physical link to the body of the Saviour. The cross itself was said to have been unearthed, along with two others, by Queen Helena, mother of Constantine the Great (c.274/88–337) at the site of Golgotha in Jerusalem. Judas revealed the true cross by using it to miraculously resuscitate a dead youth, a feat that confirmed its holy powers. The wood was brought back to Constantinople where it was coveted by many. This long panel once formed part of an altarpiece at the church of San Francesco in Ascoli Piceno, above a fragment of the cross.
