Cadmus: In Greek mythology, Cadmus ; Greek: Κάδμος "Kadmos"), was the founder and first king of Thebes.  Cadmus was the first Greek hero and, alongside Perseus and Bellerophon, the greatest hero and slayer of monsters before the days of Heracles.  Initially a Phoenician prince, son of king Agenor and queen Telephassa of Tyre and the brother of Phoenix, Cilix and Europa, he was originally sent by his royal parents to seek out and escort his sister Europa back to Tyre after she was abducted from the shores of Phoenicia by Zeus.  Cadmus founded the Greek city of Thebes, the acropolis of which was originally named "Cadmeia" in his honour.

Vulcan, Son of Giove: Vulcan, Son of Giove (Vulcano, figlio di Giove) is a 1962 Italian fantasy-adventure film directed and co-written by Emimmo Salvi in his directorial debut.  At the time of his death in 1989 he was preparing a film on "Zeus".  The film is also known as Vulcan Son of Jupiter (American TV title).  The film was partly shot in Iran.

Bellerophon: Bellerophon ( ; Greek: Βελλεροφῶν ) or Bellerophontes (Βελλεροφόντης ) is a hero of Greek mythology.  He was "the greatest hero and slayer of monsters, alongside Cadmus and Perseus, before the days of Heracles", and his greatest feat was killing the Chimera, a monster that Homer depicted with a lion's head, a goat's body, and a serpent's tail: "her breath came out in terrible blasts of burning flame."  Bellerophon was born at Corinth and was the son of the mortal Eurynome by either her husband Glaucus, or Poseidon.

Hercules: Hercules is a Roman hero and god.  He was the equivalent of the Greek divine hero Heracles, who was the son of Zeus (Roman equivalent Jupiter) and the mortal Alcmene.  In classical mythology, Hercules is famous for his strength and for his numerous far-ranging adventures.

Achaeus (son of Xuthus): In Greek mythology, Achaeus or Achaios (Ancient Greek: Ἀχαιός "Akhaios" derived from "achos" "αχος" "grief, pain, woe") was, according to nearly all traditions, a son of Xuthus and Creusa, and consequently a brother of Ion and grandson of Hellen.  Servius alone calls Achaeus a son of Jupiter (Zeus) and Pithia, probably a misspelling of Phthia, who was otherwise known as the daughter of Phoroneus compare the account of Clement.  His children were Archander and Architeles.

Iphicles: In Greek mythology, Iphicles ( or ; Ancient Greek: Ἰφικλῆς "Iphikles") was the half maternal twin brother of Heracles, being the son of Alcmene and her human husband Amphitryon, whereas Heracles was her son by Zeus.  He had a sister Laonome.  Iphicles was the father of Heracles' charioteer Iolaus by Automedusa, daughter of Alcathous.  He died in the battle against either Hippocoon or the Molionides.  He was also sometimes called Iphiclus.

Pegasus: Pegasus (Ancient Greek: Πήγασος , "Pḗgasos"; Latin: "Pegasus, Pegasos" ) is one of the best known creatures in Greek mythology.  He is a winged divine stallion usually depicted as pure white in color.  He was sired by Poseidon, in his role as horse-god, and foaled by the Gorgon Medusa.  He was the brother of Chrysaor, born at a single birthing when his mother was decapitated by Perseus.  Greco-Roman poets write about his ascent to heaven after his birth and his obeisance to Zeus, king of the gods, who instructed him to bring lightning and thunder from Olympus.  Friend of the Muses, Pegasus is the creator of Hippocrene, the fountain on Mt. Helicon.  He was captured by the Greek hero Bellerophon near the fountain Peirene with the help of Athena and Poseidon.  Pegasus allows the hero to ride him to defeat a monster, the Chimera, before realizing many other exploits.  His rider, however, falls off his back trying to reach Mount Olympus.  Zeus transformed him into the constellation Pegasus and placed him up in the sky.

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.
