Herms were mounted atop a quadrangular pillar and used as boundary markers at gateways or crossroads. They were often janiform with depictions of Dionysus including an older bearded Dionysus backing onto a younger one as in this example. For a similar herm of a young Dionysus see Berlin, Staatliche Museen, Antikensammlung Berlin, acc. no. Sk 127: C. Rückert, 'Miniaturhermen aus Stein.
