While the reverse might just be a particularly elaborate quadripartite incuse square, it may well be more meaningful than that. Like the famous tridrachms of Delphi, which show the coffered ceiling of the Apollo Temple on their reverses, the reverse of this piece might also represent the ceiling of some important building.
