​EPIGONI (“descendants”), in Greek legend, the sons of the seven heroes who fought against Thebes (see Adrastus). Ten years later, to avenge their fathers, the Epigoni undertook a second expedition, which was completely successful. Thebes was forced to surrender and razed to the ground. In early times the war of the Epigoni was a favourite subject of epic poetry. The term is also applied to the descendants of the Diadochi, the successors of Alexander the Great.
