CANTINEAE M[arci] F[iliae] PROCLAE C[aius]
IVLIVS HERMES CONIVGI PIENTISS[imae]
BENE MERENTI FECIT
To the spirits of the dead: Gaius Julius Hermes set up [this monument] for Cantinea Procla, daughter of Marcus, his most devout and well-deserving wife (CIL 6.34776; first century CE).
The portrait on this marble altar indicates that Cantinea Procla was a priestess of Isis; she holds a situla (ritual vessel for sacred water from the Nile) in her left hand and a sistrum (rattle used in rituals of Isis, now broken off) in her right. On either side of the altar are representations of the cista mystica, a wicker basket with a snake coiling around it.
