This plaque is thought to be a cover for a niche in a columbarium, or communal tomb. The Christogram--the monogram for Christ's name formed from the first two letters of his name in Greek (x and p), identifies the deceased as Christian. Scholars debate the meaning of the inscription in Latin, which may be a prayer for the deceased.
Inscription: Inscribed: BRACA RIVI/VASCUM TUIS
