The relics of saints (traditionally, always those of a martyr) are also sewn into the antimension which is given to a priest by his bishop as a means of bestowing faculties upon him (i.e., granting him permission to celebrate the Sacred Mysteries). The antimens is kept on the High Place of the Holy Table (altar), and it is forbidden to celebrate the Divine Liturgy (Eucharist) without it. Occasionally, in cases of fixed altars, the relics are built in the altar table itself and sealed with a special mixture called wax-mastic.
