Tetradrachm: Head of Alexander III [The Great] (obverse); Athena (reverse)

Much like his former commander Alexander III (the Great) showed connections to Herakles and Zeus, Ptolemy I Soter (the Savior) used coins to validate his succession to power. Thus, in place of Herakles with lion-skin, this coin shows Alexander in an elephant headdress, referring to their shared Eastern triumphs. On the reverse is Athena Promachos, striding forward with shield and spear. Before her are a helmet and an eagle, and behind her the inscription ΑΛΕΞΑΝΔΡΟΥ, “of Alexander.”
