Gnaius Pompeius Magnus, 106-48 BC, married Julius Caesar’s daughter Julia, and was a member of the First Triumvirate with Julius Caesar and Marcus Licinius Crassus, and three times a consul. After the opening of hostilities, Caesar routed him at Pharsalus and pursued him into Egypt where he was assassinated. He held the religious office of augur; during his Eastern campaign, 66-61 his troops gave him divine honors. The coin was minted posthumously in Sicily 42-40 BC by Sextus Pompeius, youngest son of Pompey the Great, and so the coin is typical of the appearance of personal images in the late Republican coins after 44 BC when they first appear. Neptune, standing on the prow of a ship, symbolizes Pompey’s military and naval power. The aplustre is a stinging shelled snail. The Catanaean brothers, Amphinomus and Anapias, are shown carrying off their parents after Mt Aetna erupted (603 BC) and the lava parted for them out of respect for their pietas. The brothers appear on one other Roman coin of M. Herinni, minted 107-108 BC. This seems a fitting theme from a son minting a dynastic coin to honor his deceased father. Alan Harway 2011.
