This mature bearded figure must represent either Zeus, the god of the sky and ruler of the Olympian deities, or his brother Poseidon, who controlled the seas. The identity would have been clear from the attribute that was originally held in the right hand. Zeus's weapon was the thunderbolt, and a sanctuary to him was established wherever lightening struck. Poseidon wielded a trident, the three-pronged spear that fishermen used to catch huge tuna.
Said to be from Cyrene, North Africa
