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.
There were few temples attributed to Ares in Ancient Greece. Sacrifices would usually be made to him when an army would march to war; Spartans would make sacrifices to Enyalius, another lesser god and son of Ares and Enyo. However, the name was also used as a byname for Ares.
When Ares went to war, he was followed by his companions, Deimos (terror) and Phobos (fear), who were the product of his union with Aphrodite. Eris, goddess of discord and sister of Deimos and Phobos, often accompanied them in war.
