• Alastor, an epithet of the Greek God Zeus, according to Hesychius of Alexandria and the Etymologicum Magnum, which described him as the avenger of evil deeds, specifically familial bloodshed. As the personification of a curse, it was also a sidekick of the Erinyes.^[3] The name is also used, especially by the tragic writers, to designate any deity or demon who avenges wrongs committed by men.^[4] In Euripides' play Electra, Orestes questions an oracle who calls upon him to kill his mother Clytemnestra, and wonders if the oracle was not from Apollo, but some malicious alastor.^[5] There was an altar to Zeus Alastor just outside the city walls of Thasos.^[6]
  • By the time of the 4th century BC, alastor in Greek had degraded to a generic type of insult, with the approximate meaning of "scoundrel".^[3]

• Alastor, a Lycian warrior who was a companion of Sarpedon. He fought in the Trojan War and was slain by the Greek hero Odysseus during the battle.^[11]
  • Alastorides is a patronymic form given by Homer to Tros, who was probably a son of the Lycian Alastor mentioned above.^[12]
