Bronze Patera Mesomphalos with Bronze Disc/Brooch previously inside from the Temple on the Sanctuary of Athena on Akropolis at Stymphalos (Peloponnesos).
Thick walled bronze patera mesomphalos with a nail hole through it for attachment to wall from temple (on right). Embedded inside the patera was a fine round bronze disk or brooch (on left) with an inset n the flat side, perhaps for the insertion of a glass piece or gem stone.
