The relief represents Hermes escorting three nymphs and, at the back, the forepart of the river god Acheloös who is represented in the form of a bull. A mound stands for a rustic altar. The retrospective style of the relief imitates works of the Archaic period (ca. 600–480 B.C.). Numerous votive reliefs of this type, dedicated to Hermes, Pan, and the nymphs, have been found in Greece. In most of these scenes, a grotto marks the locality; this relief is unusual for its architectural frame.
