Title: Phaethon
Content:  Phaethon, also spelled Phaëthon, was the son of the Oceanid Clymene and the sun god Helios in Greek mythology. His name was also used by the Ancient Greeks as an alternative name for the planet Jupiter, the motions and cycles of which were personified in poetry and myth. In most authors, Phaethon is the son of Helios, and out of desire to have his parentage confirmed, travels to the sun-god's palace in the east. There he is recognised by his father, and asks him for the privilege to drive his chariot for a single day. Despite Helios' fervent warnings and attempts to talk him out of it, counting the numerous dangers he would face in his celestial journey and reminding Phaethon that only he can control the horses, the boy is not dissuaded and does not change his 
Title: Helios
Content:  Helios (Modern Greek: Ήλιος; ; Homeric Greek: Ἠέλιος), Latinized as Helius, often given the epithets Hyperion ("the one above") and Phaethon ("the shining"), is the god and personification of the Sun (Solar deity) in ancient Greek religion and myth, often depicted in art with a radiant crown and driving a horse-drawn chariot through the sky. He was a guardian of oaths and also the god of sight. Though Helios was a relatively minor deity in Classical Greece, his worship grew more prominent in late antiquity thanks to his identification with several major solar divinities of the Roman period, particularly Apollo 
Title: Solar deity
Content:  In Greek mythology, Helios, a Titan, was the personification of the Sun; however, with the notable exception of the island of Rhodes and nearby parts of southwestern Anatolia, he was a relatively minor deity. The Ancient Greeks also associated the Sun with Apollo, the god of enlightenment. Apollo (along with Helios) was sometimes depicted as driving a fiery chariot. The Greek astronomer Thales of Miletus described the scientific properties of the Sun and Moon, making their godship unnecessary. Anaxagoras was arrested in 434 BC and banished from Athens for denying the existence of a solar or lunar deity. The titular character of Sophocles' Electra refers to the Sun as "All-seeing". Hermetic author Hermes Trismegistus calls the Sun "God Visible". The Minotaur has been interpreted as a solar deity (as Moloch or Chronos), including by Arthur Bernard Cook, who considers both Minos and Minotaur as aspects of the sun god of the Cretans, who depicted the sun as a bull.
Title: Alectryon (mythology)
Content:  Ares, fearing that his illicit liaison with Aphrodite would be discovered and being especially suspicious of Helios, tasked Alectryon (according to Lucian, Alectryon was said to have been 'an adolescent boy, beloved of Ares, who kept company with the god at drinking parties, caroused with him, and was his companion in lovemaking') with standing guard outside of his room as the two gods made love. Alectryon fell asleep on guard duty and Helios discovered them the following morning. The sun-god then alerted Hephaestus, Aphrodite's husband, to the actions of the two, prompting the god of fire to create a net to ensnare and shame them. Furious, Ares punished Alectryon by turning him into a rooster which never forgets to announce the arrival of the sun in the morning by its crowing, his own way of apologizing to Ares for falling asleep, however this failed to make amends. According to Pausanias, the rooster is Helios' sacred animal, always crowing when he is about to rise.
Title: Icarus
Content:   In Greek mythology, Icarus was the son of the master craftsman Daedalus, the creator of the Labyrinth. Icarus and Daedalus attempt to escape from Crete by means of wings that Daedalus constructed from feathers and wax. Daedalus warns Icarus first of complacency and then of hubris, instructing him to fly neither too low nor too high, lest the sea's dampness clog his wings or the sun's heat melt them. Icarus ignores Daedalus’s instructions not to fly too close to the sun, causing the wax in his wings to melt. He tumbles out of the sky, falls into the sea, and drowns. The myth gave rise to the idiom "don't fly too close to the sun".
Title: Cattle of Helios
Content:  Helios, who in Greek mythology is the Titan of the Sun, is said to have had seven herds of oxen and seven flocks of sheep, each numbering fifty head. In the Odyssey, Homer describes these immortal cattle as handsome (ἄριστος), wide-browed, fat (εὐρυμέτωπος) and straight-horned (ὀρθόκραιρος). The cattle were guarded by Helios’ daughters, Phaëthusa and Lampetië, and it was known by all that any harm to any single animal was sure to bring down the wrath of the god. Tiresias and Circe both warn Odysseus to shun the isle of Helios (Thrinacia). Odysseus and his crew arrive at Thrinacia after passing Scylla and Charybdis. When Eurylochus begs to be allowed to land to 
Title: Phaethon
Content:  In the True History by the satirical Greek writer Lucian of Samosata, Phaethon is the king of the sun and is at war with the Moon, ruled by King Endymion. In his Dialogues of the Gods, Zeus angrily berates Helios for letting his inexperienced son drive his chariot, which almost resulted in the world being destroyed. Helios acknowledges his error, but claims he was pressured by Phaethon and Phaethon's mother Clymene both, and could have not foreseen the extent of the disaster; Zeus is displeased to hear it, unconvinced that he would not know that an inexperienced driver like Phaethon would not be able to control the steeds. Helios then asks Zeus to be merciful, as his son has already been punished (being dead) and he himself is in great mourning. Zeus disagrees that this punishment is enough, returns Helios his damaged chariot which is in need of repair, and threatens to strike him with one of his thunderbolts should he ever do such thing again.
Title: Phaethon
Content:  Phaethon was said to be the son of the Oceanid Clymene and the sun god Helios. Alternatively, less common genealogies make him a son of Clymenus by Oceanid Merope, of Helios and Rhodos (thus a full brother of the Heliadae) or of Helios and Prote. Details vary according to version, but most have Phaethon travel far east to meet his father, sometimes in order to get him to assure his paternity. There, he asks Helios for permission to drive his father's sun-chariot for a single day. Despite Helios' protests and advice against, Phaethon doesn't back down from his initial wish, and thus Helios reluctantly allows him to drive his chariot. Placed in charge of the chariot, Phaethon was unable to control the horses. In some versions, the Earth first froze when the horses climbed too high, but when the chariot then scorched the Earth by swinging too near, Zeus decided to prevent disaster by striking it down with a thunderbolt. Phaethon fell to earth and was killed in the process.
Title: Dialogues of the Gods
Content:  Hermes goes to find the Sun, to announce to him Zeus' order not to rise for three days. The Sun is worried that he has done something wrong and this is his punishment, but Hermes reassures him that it's nothing of that kind; Zeus is in love with the wife of Amphitryon and wants to be with her. He means to sire a great hero, mightier than any other, with her, and needs time for that. The Sun agrees, but complains about Zeus' actions' consequences to the world, and unfavourably compares him to Cronus, who never abandoned Rhea for the sake of some mortal woman. Hermes tells him to hush, for he will get into trouble should anyone hear him, and goes off to give the same message to the Moon and Sleep.
Title: Cygnus (constellation)
Content:  In Greek mythology, Cygnus has been identified with several different legendary swans. Zeus disguised himself as a swan to seduce Leda, Spartan king Tyndareus's wife, who gave birth to the Gemini, Helen of Troy, and Clytemnestra; Orpheus was transformed into a swan after his murder, and was said to have been placed in the sky next to his lyre (Lyra); and the King Cygnus was transformed into a swan. The Greeks also associated this constellation with the tragic story of Phaethon, the son of Helios the sun god, who demanded to ride his father's sun chariot for a day. Phaethon, however, was unable to control the reins, forcing Zeus to destroy the chariot (and Phaethon) with a thunderbolt, causing it to plummet to the earth into the river Eridanus. According to the myth, Phaethon's close friend or lover, Cygnus, grieved bitterly and spent many days diving into the river
