Plutarch Theseus 27.4:
Here, he says. the Athenians were routed and driven back by the women as far as the shrine of the Eumenides, but those who attacked the invaders from the Palladium and Ardettus and the Lyceum, drove their right wing back as far as to their camp, and slew many of them. And after three months, he says, a treaty of peace was made through the agency of Hippolyta; for Hippolyta is the name which Cleidemus gives to the Amazon whom Theseus married, not Antiope. But some say that the woman was slain with a javelin by Molpadia, while fighting at Theseus’s side, and that the pillar which stands by the sanctuary of Olympian Earth was set up in her memory (original Greek).
On entering the city there is a monument to Antiope the Amazon. This Antiope, Pindar says, was carried off by Peirithous and Theseus, but Hegias of Troezen gives the following account of her. Heracles was besieging Themiscyra on the Thermodon, but could not take it, but Antiope, falling in love with Theseus, who was aiding Heracles in his campaign, surrendered the stronghold. Such is the account of Hegias. But the Athenians assert that when the Amazons came, Antiope was shot by Molpadia, while Molpadia was killed by Theseus. To Molpadia also there is a monument among the Athenians (original Greek).
Ovid Heroides 4.119-20:
If you ask where she is: Theseus pierced her side with a sword. The mother was not safe by such a pledge (translated by Aaron J. Ivey).
Hyginus Fabulae 241:
Hercules, son of Jove, killed Megara, daughter of Creon, in a fit of insanity.
Theseus, son of Aegeus, killed Antiopa, the Amazon, daughter of Mars, because of an oracle of Apollo.
Cephalus, son of Deion or of Mercury, killed Procris, daughter of Pandion, unwittingly (original Latin).
