Who was Heracles?

” Heracles (/ˈhɛrəklz/ HERR-ə-kleez; Ancient Greek: ἩρακλῆςHēraklēs, from Hēra, “Hera”), born Alcaeus (ἈλκαῖοςAlkaios) or Alcides (ἈλκείδηςAlkeidēs), was a divine hero in Greek mythology, the son of Zeus and Alcmene, foster son of Amphitryon and great-grandson and half-brother (as they are both sired by the god Zeus) of Perseus. He was the greatest of the Greek heroes, a paragon of masculinity, the ancestor of royal clans who claimed to be Heracleidae (Ἡρακλεῖδαι), and a champion of the Olympian order against chthonic monsters. In Rome and the modern West, he is known as Hercules, with whom the later Roman emperors, in particular, Commodus and Maximian, often identified themselves. The Romans adopted the Greek version of his life and work essentially unchanged, but added an anecdotal detail of their own, some of it linking the hero with the geography of the Central Mediterranean. Details of his cult were adapted to Rome as well.” https://en.wikipedia.org/wiki/Heracles
