The oval stone is engraved with Hygieia, the daughter of the god Asklepius and personification of health, her hair bound up and wearing a long chiton. She is offering a dish, held in her outstretched hand, to her father's healing serpent which is coiled in front and behind her body. A popular motif on Roman gems, cf. cf. M.
