Who were Telphus' grandparents on his father's side?
Heracles Heracles ( ; Ancient Greek: Ἡρακλῆς , "Hēraklēs", from "Hēra", "Hera"), born Alcaeus (Ἀλκαῖος , "Alkaios") or Alcides (Ἀλκείδης , "Alkeidēs"), 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 works essentially unchanged, but added 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.
Melampus In Greek mythology, Melampus (Ancient Greek: Μελάμπους , "Melampous"), was a legendary soothsayer and healer, originally of Pylos, who ruled at Argos. He was the introducer of the worship of Dionysus, according to Herodotus, who asserted that his powers as a seer were derived from the Egyptians and that he could understand the language of animals. A number of pseudepigraphal works of divination were circulated in Classical and Hellenistic times under the name Melampus. According to Herodotus and Pausanias (vi.17.6), on the authority of Hesiod, his father was Amythaon, whose name implies the "ineffable" or "unspeakably great"; Thus Melampus and his heirs were "Amythaides" of the "House of Amythaon".
