This floor mosaic from the House of the Faun in Pompeii shows Alexander the Great, bareheaded on his horse Bucephalus, charging the Persian king Darius III, who turns in his chariot to flee. Laid in over a million tiny tesserae in reds, yellows, black and white, it probably copies a lost Greek painting of about 300 BCE, sometimes attributed to Philoxenus of Eretria.
Look closer
Below Darius, a fallen Persian soldier sees his own dying face reflected in a polished shield. Nearby, a horse is shown from behind in steep foreshortening.
