These remnants of a head are sufficient to render all the delicacy and precision of such a portrait. The treatment of the face corresponds to the conventions of Achaemenid portraiture: a sharp, aquiline nose; delicately outlined almond eyes; and a curly beard. R. Ghirsman mentions in this context a lapis lazuli sculpture in the round, probably depicting a Mede carrying a lion cub. The National Museum of Iran in Tehran also has in its collections a head executed in the same material, depicting a prince and coming from Persepolis.
