Re: Athens Attica Emergency Issue TetraDrachm
Its famous 'owl' coinage, principally of silver tetradrachms, possibly commenced in 510 BC on the occasion of the downfall of the tyrant Hippias. On these celebrated coins the helmeted head of the goddess Athena was accompanied by her attendant owl and the first three letters of the ethnic 'AQE'. Later, a diadem of olive leaves was added to Athena's helmet and a cresent moon was placed in the reverse field, though the precise chronological significance of these changes remains uncertain. To the intense chagrin of the Spartans Athens became the leader of the Greek states, including those of Ionia, in the epic struggle against the expansionist policies of the Achaemenid Persian Empire.???
