Hippomedon (Seven against Thebes)

[3] In Euripides' The Suppliants, he is characterized as a person uninterested in comfort and entertainments, eager to face hardships, and dedicating a lot of time to training for combat.

He bears the image of a fire-breathing typhon on his shield and attacks the gate of Athena Onca, and is confronted by Hyperbius, son of Oenops.

[11] In Euripides' Phoenician Women, he has the image of Argus Panoptes on his shield and assails the Ogygian Gates.

In Book 9 he engages in the fight over the body of Tydeus, and when the attempt to seize it back from the Thebans fails, he goes on slaying one opponent after another and in the course of the battle, descends into the waters of River Ismenus.

The latter, upon discovering her son's dead body, implores her father, the river god Ismenus, to avenge the youth's death.
