Poseidon was son of Kronus and Rhea，and brother ofZeus．After the war with the Titans，he became the mighty and majestic god of the sea，ruling all the water saround the earth．He was considered to have the greatest power next to Zeus ．Poseidon ruled his kingdom with cold shaking．He could call up all the big winds and stir up or calm down the stormy oceans． with a trident in his hand ，he flew across the waves in a carriage drawn by horses with bronze hoofs and golden hairs．Although he had a seat on Olympus，he lived，most of the time，in his shining golden palace in the deeps of the oceans．
Poseidon was ambitious and aggressive ．Unhappy with the part of power given to him，he planned to throw down Zeus from his high position．The plan did not come off，and he was senta way to serve a human being on earth． with the help of Apollo he built the famous walls of Troy for king Laomed on．On one occasion he argued with Athena over the naming of the new city Athens and was forced to give in to the goddess of wisdom．On another he entered into a bitter dispute with Apollo over the king of Corinth and won the case in the end．
