The mirror with pear-shaped plate, depicts Achilles' journey to the Isle of the Blessed. It shows the warrior wearing an Attic helmet with a long flowing horsehair crest, a chlamys over his shoulders and knotted at the chest. He is seated astride a hippocamp, a mythical part horse, part sea-creature, his right arm placed on the flanks of the beast supporting his weight, and accompanied by a dolphin. Filmy seaweed-like fins and tail to the creature. The polished side with viridian green encrustation to the majority of the surface. Above the handle flange is incised decoration of a palmette between acanthus leaves. The short metal flange would have been set into a handle of wood, bone or ivory, now lost. Some small losses to the raised rim of the decorated side.
