Panaenus

Panaenus (Ancient Greek: Πάναινος), brother or nephew of Phidias, was an ancient Greek painter who worked in conjunction with Polygnotus and Micon at Athens.^[1][2]

The painting of the Battle of Marathon in the Stoa Poikile is ascribed to Panaenus and to Micon and Polygnotus, who may have assisted him.^[3]

He also painted the marble sides of the throne of the statue of Zeus erected by Phidias at Olympia.^[1]
