Homarium

The Homarium, Homagyrium or Amarion (Ancient Greek: Ἀμάριον) was the common sanctuary of the Achaean League, built c. 371 BC at Aegium.

It was so named as it was dedicated to Zeus Amarios (Ancient Greek: Ἀμάριος) or Homarios (Ὁμάριος) or Homagyrios (Ὁμαγύριος) (Latinized as Homarius and Homagyrius, the exact meaning of the epithets is uncertain, but probably "god of the assembly, he who unites"),[1] and was used, according to Polybius, for meetings and debates on Achaean lines.

Again, according to Polybius [5:93] resolutions to internal Achaean disputes during the Social War were recorded on a stele erected near the altar of Hestia or Vesta.

Nineteen states of the Achaean League minted triobols (or hemidrachms), small silver coins worth three obols, carrying a bust of Zeus Amarios on the obverse.

[6] Later bronze coins were minted by the members of the league, also bearing the image of Zeus Amarios, holding a miniature Nike, presenting him a wreath.
