Athena on the Temple of Apollo at Eretria 
The gorgoneum on the aegis of the Goddess is exceptionally prominent.
It recalls the earlier role of gorgons at the pediment centers.
The Temple of Apollo at Eretria in Euboea was destroyed by the Persians on their way to defeat at Marathon in 490 BCE.
The city had been closely associated with Athens, and despite the Temple's occupant it is Athena who stands at the pediment's center (this seems to be the back pediment, however).
About 500-490 BCE, Height 0.74 m
Chalcis, Museum 5
