The Myth of Poseidon, God of the Sea Poseidon was the brother of Zeus, and just as Zeus ruled over the land and the sky, Poseidon ruled over the rivers and the seas. He was always represented as carrying a trident, or fish-spear with three points. When he struck the sea with this, fierce storms would arise; then with a word he could quiet the dashing waves, and make the surface of the water as smooth as that of a pond.
The palace of Poseidon was said to be at the bottom of the sea. It was made of shells and coral, fastened together with gold and silver. The floors were of pearl, and were ornamented with all kids of precious stones. Around the palace were great gardens filled with beautiful sea-plants and vines. The flowers were of the softest and most delicate tints, and were far more beautiful than those growing in the light of the sun. The leaves were not of the deep green which we see on land, but of a most lovely sea-green color. If you should ever go to the sea-coast, and look down through the water, perhaps you also might see the gardens of Poseidon lying among the rocks at the bottom of the sea.
Poseidon rode over the surface of the sea in a chariot made of a huge sea-shell, which was drawn by great sea-horses with golden hoofs and manes. At the approach of the god, the waves would grow quiet, and strange fishes and huge sea-serpents and sea-lions would come to the surface to play about his chariot. Wonderful creatures called Tritons went before and beside his chariot, blowing upon shells as trumpets These Tritons had green hair and eyes; their bodies were like those of men, but instead of legs they had tails like fishes.
Nymphs also swam along by the sea-god’s chariot. Some of these were like the Tritons, half human and half fish. Others were like lovely maidens, with fair faces and hair. Some lived so much in the depths of the sea that their soft blue eyes could not bear the light of day. So they never left the water except in the evening, when they would find some quiet place upon the shore, and dance to the music which they made upon delicate sea-shells.
Poseidon once had a quarrel with one of the goddesses over a piece of land which each one wished to own, and at last they asked the other gods to settle the dispute for them. So at a meeting on Mount Olympus the gods decided that the one who should make the most useful gift to the people should have the land.
When the trial came, Poseidon thought that a spring of water would be an excellent gift He struck a great blow with his trident upon a rocky hill that stood in that land, and a stream of water gushed forth. But Poseidon had lived so much in the sea that he had forgotten that men could drink only fresh water. The spring which he had made was as salt as salt could be, and it was of no use to the people at all. Then the goddess, in her turn, caused an olive-tree to spring up out of the ground. When the gods saw how much use men could make of its fruit and oil, they decided that the goddess had won. So Poseidon did not get the land; but ever afterward the people showed the salt spring and the olive-tree upon the hill-top as a proof that the trial had taken place.
Poseidon was worshiped most by the people who lived by the shore of the sea. Every city along the coast had a temple to Poseidon, where people came to pray to him for fair weather and happy voyages for themselves and for their friends.
