Nicomachus of Thebes

Nicomachus of Thebes (; fl. 4th century BC) was an ancient Greek painter, a native of Thebes, and a contemporary of the great painters of the Classical period. He trained under his father Aristides, also a painter.
Pliny gives a list of his works; among them a "Rape of Proserpina", "Victory in a Quadriga", "Apollo and Diana", and "Cybele seated on a Lion". Many of his works were taken to Rome. Pliny tells us that he was a very rapid worker and claims that he was one of the painters who used only four colors. Plutarch mentions his paintings as possessing the Homeric merit of ease and absence of effort. Cicero equally praises his works. Vitruvius observes that if his fame was less than his contemporaries, it was the fault of fortune rather than a lack of talent.
Among his students were his young brother Ariston, his son Aristides of Thebes, and Philoxenus of Eretria.
