On the upper surface of the lid a Christogram is framed by the Alpha and Omega, the apocalyptic letters, while the lateral sides are decorated with vine leaves and grapes.

Reliquaries were made of precious materials (gold, silver, ivory) and contained relics of martyrs and saints or objects which had been sanctified by contact with relics, such as blood-soaked earth from a saint’s tomb. They were placed on the altar or underneath it when the church was consecrated.
