Macedonian Kingdom, Demetrius I Poliorketes, 306 - 283 B.C., Silverdrachm

The bull's horns suggest Demetrius' relationship to Poseidon is the same as Alexander's to Zeus Ammon. The portrait is individualized, but evokes the image of Alexander. Demetrios was the first to assimilate elements of Alexander's deified portrait and the first living ruler to portray himself as a god on coins.
