Lot Essay
Ammon was originally an Egyptian god whose worship was centered at Thebes. He appears in Greek literature due to his temple at the oasis at Siwa, where there was an oracle that came to rival those at Delphi and Dodona. In Greek art he is usually portrayed as Zeus, with the addition of ram's horns. By the 4th century B.C. he is often shown beardless, as here. The Siwa oracle became famous following a visit by Alexander the Great, where the young Macedonian was proclaimed the son of Zeus. Numismatic portraits of Alexander depict the youthful conqueror wearing the horns of Ammon in a manner strikingly similar to this vase. See nos. 161-185 in Leclant and Clerc, "Ammon," in LIMC.
