Kronos once ruled over the world before the gods of Olympus took their place. An oracle foretold that one of his children would overthrow him, so Kronos decided to devour all of his offspring.

However, Poseidon, the future god of the seas, was saved from this fate thanks to the wisdom and determination of his mother, Rhea. Rhea deceived Kronos by presenting him with a foal as a supposed child, which he then swallowed. Meanwhile, she hid Poseidon safely among a flock of sheep. The young Poseidon was cared for by Arne, the daughter of the wind god Aeolus, and was raised by the legendary Telchines, mystical beings with great craftsmanship, who later forged the trident for him—a symbol of his power.

Thanks to the skills of these extraordinary craftsmen, Poseidon learned the art of crafting early on. They gifted him his iconic trident, an instrument of great power that served him in the battle against Kronos. Together with his brothers, including Zeus, Poseidon led the Olympian gods to victory and, after their triumph, secured his dominion over the world's seas.

Poseidon, as the god of the seas, possessed great attraction and power. His official consort was Amphitrite, the goddess of the calm sea. Although Amphitrite was initially hesitant to marry him, she was convinced by a loyal messenger of the sea god, who sought her hand on Poseidon’s behalf. As a token of his appreciation, Poseidon gifted her a splendid crown of pearls and shells, symbolizing her power over the peaceful waters.

Poseidon’s powerful and dynamic nature led to numerous connections with goddesses, nymphs, and mortals, resulting in many children of great significance. One of his lovers was Tyro, who had fallen in love with a river god. Poseidon, enchanted by her beauty, approached her in the form of the river god. From this union came Pelias and Neleus, two sons who would become significant heroes in Greek mythology.

When Leto, the lover of Zeus, was pregnant with Apollo and Artemis, she sought a safe place to give birth to her children, but no land would receive her, fearing Hera's wrath. Poseidon then took the island of Delos and anchored it securely in the sea, allowing Leto to bring her children into the world there. Thus, Delos became a sacred place for the worship of Apollo and Artemis.
