Ares

As I have promised, I will make more of the gods and then move on to Egyptians gods which will be a very long one. Ares was the god of war, and son of Zeus and Hera. He represented the raw violence and untamed acts that occured in wartime, in contrast to Athena, who was a symbol of tactical strategy and military planning.

He was disliked by both his parents. Whenever Ares appeared in a myth, he was depicted as a violent personality, who faced humiliation through his defeats more than once. In the Iliad, it is mentioned that Zeus hated him more than anyone else; Ares was also on the losing side of the Trojan War, favouring the Trojans. He was the lover of his sister, Aphrodite, who was married to Hephaestus. When the latter found out about the affair, he devised a plan and managed to humiliate both of them. The union of Ares and Aphrodite resulted in the birth of eight children, including Eros, god of love.
