Alexander the Great (356–323 BC), the King of Macedonia, as depicted in a detail from the Alexander Mosaic. Originally from the House of the Faun in Pompeii and dated to c. 100 BC, the mosaic depicts a battle between the armies of Alexander the Great and Darius III of Persia. It is believed to be a copy of an early 3rd century BC Hellenistic painting, probably by Philoxenos of Eretria. The whole mosaic measures 2.72 × 5.13 m (8 ft 11 in × 16 ft 9 in).
