Aldrich) (Greek mythographer C2nd A.D.) : "
As the god of horses, Poseidon is thought likely to have been introduced to Greece by the earliest Hellenes, who also introduced the first horses to the country about the 2nd century bce. Poseidon himself fathered many horses, best known of which was the winged horse Pegasus by the Gorgon Medusa.
Poseidon's Affairs
Demeter, trying to avoid her brother, turned into a mare, but Poseidon responded by turning into a stallion and having his way with her anyway. The product of this union was the divine horse, Arion.
Poseidon presented the horse, a valuable animal that could help in work, battle, and transportation (note that in some stories he presents a well of sea water instead of the horse).
Demeter also had a mortal lover named Iasion. According to this story, known from a handful of ancient sources, Demeter slept with Iasion in a thrice-plowed field, often said to have been located in Crete.
After Rhea refused to marry him, Zeus turned into a snake and raped her. Rhea became pregnant and gave birth to Persephone. Zeus in the form of a snake would mate with his daughter Persephone, which resulted in the birth of Dionysus.
According to the Orphic myths, Zeus wanted to marry his mother Rhea. After Rhea refused to marry him, Zeus turned into a snake and raped her. She had Persephone with Zeus.
AREION (Arion) An immortal horse owned by the heroes Herakles and Adrastos. He was the son of Poseidon and Demeter, born following their mating in the shape of horses.
Along comes the god of the sea – Poseidon who rapes Medusa in Athena's temple – the Parthenon. In doing this Medusa is no longer eligible to serve the goddess or legitimately marry.
Pegasus, the divine, winged white horse, was the offspring of the god Poseidon and the gorgon Medusa. He was born from Medusa's blood after she was beheaded by Perseus, arising from her head or from the blood that had seeped into the earth.
Some estimates put the count at well over a hundred, with the lovers being mostly but not exclusively female. In some cases, ancient authorities differ, so the exact lineage and relationships remain open to debate.
APHRODITE The goddess of love and beauty was loved by Poseidon and, according to some, bore him two daughters Rhode and Herophile (though both daughters are given alternative parents by other authors).
So, when Poseidon raped Medusa she became pregnant. When her head was chopped off by Perseus, her children came to be. Pegasus and Chrysaor sprung from the severed neck of Medusa. Pegasus is also one of the most famous characters in Greek mythology, the winged white horse.
Pegasus was eventually brought to Olympus by Zeus. There, he was stabled next to Zeus' thunderbolts. One of his duties included carrying Zeus' thunderbolts.
In Gallo-Roman religion, Epona was a protector of horses, ponies, donkeys, and mules. She was particularly a goddess of fertility, as shown by her attributes of a patera, cornucopia, ears of grain, and the presence of foals in some sculptures.
Hades, the Greek god of the underworld, had a powerful black horse named Alastor who was one of the four horses that pulled his chariot when he charged out of the underworld to bring Persephone back to live with him.
Medusa and Poseidon engaged in a love affair and would have two children together, but not before Athena discovered the illicit affair. When Athena discovered the affair, she was enraged and immediately cursed Medusa by taking away her beauty.
Like his brother Zeus, Poseidon is a famous womanizer. He is married to the sea goddess, Amphitrite, but that doesn't stop him from sleeping with everybody in sight.
The snake-haired Medusa does not become widespread until the first century B.C. The Roman author Ovid describes the mortal Medusa as a beautiful maiden seduced by Poseidon in a temple of Athena. Such a sacrilege attracted the goddess' wrath, and she punished Medusa by turning her hair to snakes.
His first and favorite lover was Metis, a Titan goddess and mother of Athena.
Poseidon claims Percy is his favorite son but he has at least two other good ones that have been just as Great: Thesus- Great King of Athens who slayed the minotaur (Posiedon's mistake) and did a bunch of other Heroic stuff.
Medusa. The Medusa we know was raped by Poseidon in the goddess Athena's temple. Athena then punished her for desecrating her sacred space by cursing Medusa with a head full of snakes and a gaze that turns men to stone. Then, a heroic Perseus severed the serpent-headed Medusa, turning her into a trophy.
Before his marriage to Hera, Zeus consorted with a number of the female Titanes (and his sister Demeter). These liaisons are ordered by Hesiod as follows: (1) Metis; (2) Themis; (3) Eurynome; (4) Demeter; (5) Mnemosyne; (6) Leto.
Aphrodite later and of her own volition had an affair with Zeus, but his jealous wife Hera laid her hands upon the belly of the goddess and cursed their offspring with malformity. Their child was the ugly god Priapos.
Zeus was known in his time as much more than the father of the gods. He was also a womanizer, and as such, he fathered many, many offspring! He would transform into various animals to fulfill his desires; therefore, his 'children' are quite interesting.
