Why was Poseidon responsiblie for the sea?

In Greek mythology, Poseidon was the god of the sea, earthquakes, and storms. He was considered one of the Olympian gods and was revered by the ancient Greeks for his power and control over the ocean. Several factors and mythological events contribute to how Poseidon came to be responsible for the sea:

- His divine lineage: Poseidon was the son of Cronus and Rhea, the supreme deities of the Titans. After the Olympian gods overthrew the Titans, the world was divided among the three brothers: Zeus, Hades, and Poseidon. Poseidon received the realm of the seas.

- Ancient religious beliefs: The ancient Greeks attributed the power of the ocean to powerful divine entities. They saw the vast and unpredictable nature of the sea as something beyond human comprehension and believed that only a powerful god could maintain order and prevent chaos. Poseidon, as a major deity, naturally assumed this role.

- Patronage of seafarers: Sailors, fishermen, and those who depended on the sea for trade or livelihood held Poseidon in high regard. They prayed to him for safe passage, favorable winds, and protection from storms and sea monsters. In return, Poseidon was known to favor seafarers and reward their devotion.

- Myths and tales: Poseidon appears in numerous Greek myths and legends related to the sea. For instance, in the famous tale of Odysseus, Poseidon becomes enraged when the hero Odysseus blinds his son, the Cyclops Polyphemus. This leads to numerous trials and obstacles that Poseidon places in Odysseus's path during his homecoming voyage. These stories further solidified Poseidon's association with the sea.

Over time, Poseidon's role as the Greek god of the sea became deeply ingrained in mythology and ancient society. He embodied the mysteries and unpredictable power of the vast ocean, and various cultural practices, religious rituals, and artistic representations reflected his profound influence over the marine realm.
