Some of the best epics are not told in a single story, so therefor, I will kick off a mini series today: the labours of Hēraklēs. Hēraklēs (Ἡρακλῆς), from 'Hera' and kleos, 'glory', was born as Alkaios (Ἀλκαῖος) or Alkeidēs (Ἀλκείδης). He became on of the greatest of the divine heroes in Hellenic mythology, and was born the son of Zeus and Alkmene (Ἀλκμήνη), foster son of Amphitryon (Ἀμφιτρύων), king of Tiryns in Argolis. By Alkmene, he is the great-grandson of Perseus, and by Zeus, his half-brother. He is perhaps better known as Hercules, his Roman counterpart. In this first part, I will introduce Hēraklēs and describe his life up until the labours, and then tackle the labours one at a time in coming editions.
Hēraklēs was conceived by Zeus upon Alkmene, as He disguised Himself as her husband, returning early from war. Alkmene accepted Him in her bed gladly, as she was happy to see her husband again. When The real Amphitryon did return later that night, Alkmene realized what had happened, and told her husband. Amphitryon accepted her in his bed, regardless, and so she became pregnant with twins, one fathered by Zeus, and one by her mortal husband. In the words of Apollodorus:
"But before Amphitryon reached Thebes, Zeus came by night and prolonging the one night threefold he assumed the likeness of Amphitryon and bedded with Alcmena and related what had happened concerning the Teleboans. But when Amphitryon arrived and saw that he was not welcomed by his wife, he inquired the cause; and when she told him that he had come the night before and slept with her, he learned from Tiresias how Zeus had enjoyed her. And Alcmena bore two sons, to wit, Hercules, whom she had by Zeus and who was the elder by one night, and Iphicles, whom she had by Amphitryon." [2.4.8]
