According to legend, Alexander went on pilgrimage to the
Siwa Oasis, the sanctuary of the Greco-Egyptian deity
Zeus Ammon in 331 BC. There, he was pronounced by the
Oracle to be the son of Zeus Ammon, allowing him to therefore have the
Horns of Ammon, which themselves followed from Egyptian iconography of Ammon as a ram-headed god or, in his Greek form, a man with ram horns. The complete imagery may have represented a hybrid depiction that combined the naturalistic face of Zeus' portraiture with Ammon's horns depicting the Egyptian deity in order to signify the emergence of a new political system that encompassed the world, across regions such as Greece, Egypt, Persia, and so forth. This continued under
Arsinoe II from 275 to 268 BC. It was not for another two centuries that this practice was revived by
Mithridates VI Eupator in the 1st century BC, after which numismatic representations of a two-horned Alexander ceased. Representations would continue in the form of literature, sculptures, and other artistic expressions continued. A life-sized marble head of Alexander with Ammon's ram horns is known from the second half of the second century and is stored at the
National Museum of Denmark in
Copenhagen. The popular practice of representing Alexander with horns among sculptors was described by
Clement of Alexandria in the third century AD, who wrote "Alexander wished to be thought the son of Ammon and to be modeled with horns (κερασφόρος) by sculptors, so eager was he to outrage the beautiful face of a man by a horn." Roughly in the same period, the grammarian
Athenaeus of Naukratis reported that one of Alexander's contemporaries,
Ephippus of Olynthus, stated that "Alexander used to wear even the sacred vestments at his entertainments; and sometimes he would wear the purple robe, and cloven sandals, and horns of Ammon, as if he had been the god." In April 2024, the discovery of a bronze fitting depicting a two-horned Alexander with wavy hair was announced, discovered in
Zealand, an island of
Denmark. The artifact is dated to ~200 AD during the reign of the emperor
Caracalla, an emperor that believed himself to be the reincarnated Alexander. == Late antiquity ==
