ギュスターヴ・モロー
Thespius' maternal grandparents were Phrasimus and Diogenia, the daughter of the river god Cephissus. He married Megamede, daughter of Arneus. They supposedly had fifty daughters together, although Thespius may have fathered some of the daughters from unnamed mistresses with Megamede being their stepmother. The daughters are often referred to as the Thespiades, also being the subject of an 1853 painting by Gustave Moreau.
