AR Tetradrachm of Syracuse

The obverse side has the head of Arethusa, who was a nymph and daughter of Nereus. She fled her home, Arcadia, beneath the sea and came up as a fresh spring in Syracuse. Her figure is surrounded by four dolphins, who helped in her escape. 

The reverse of this coin depicts a charioteer driving a quadriga pulled by horses. Above is Nike, the goddess of victory, crowning the four horses which represented the victory they brought to Syracuse.
