Melanippus
In Greek mythology, there were eleven people named Melanippus (Μελάνιππος):
Melanippus, one of the sons of Agrius, killed by Diomedes.
Melanippus, son of Perigune and Theseus, the father of Ioxus who, together with Ornytus, led a colony to Caria and became the ancestor of the family Ioxides.
Melanippus, sometimes misspelled "Menalippus", son of Astacus (hence referred to by the patronymic Astacides in Ovid), defender of Thebes in Seven Against Thebes. In Aeschylus' play, he defended the Proitid gate against Tydeus. He killed two of the seven attacking champions, Mecisteus and Tydeus, but was killed by either Amphiaraus, or Capaneus, or by Tydeus himself as he died. (In versions where Melanippus is killed by someone other than Tydeus, the slayer decapitates him and delivers his head to Tydeus). Tydeus broke Melanippus' skull open and consumed his brain, which disgusted Athena so that she gave up her intent of making Tydeus immortal. Herodotus relates how in historical times, Cleisthenes abolished the hero cult of Adrastus in Sicyon in favour of that of Melanippus.
