Reliquary crosses were purchased at pilgrim centres and were designed to enclose a relic; normally part of the True Cross. They were generally worn around the neck. Such crosses, along with their relics, were produced in large numbers, being cast either from a mould or by means of the lost-wax process. They were frequently engraved with religious figures, the most common being the crucified Christ, but others such as the Virgin Mary and Saints George, Peter and John were also depicted in the 'orans' position with arms raised in prayer.
