Ares is the God of War, son of Zeus and Hera, 
and one of the most prominent and powerful Gods of Olympus. 
He was born after the Great War and has served his father faithfully. 
He was also a rival of Athena, who is his younger sister.
 They were rivals because they were both gods of war and wished that the other stood down and let the other win.
 His Roman counterpart was Mars. Although Ares was held in much higher esteem, 
second only to Cronos; Ionic form of the Doric

ARES was the great Olympian god of war, battlelust, civil order and manly courage. 
In Greek art he was depicted as either a mature, bearded warrior dressed in battle arms, 
or a nude beardless youth with helm and spear. 
Because of his lack of distinctive attributes he is often difficult to identify in classical art.

Ares plays a relatively limited role in Greek mythology as represented in literary narratives, though his numerous love affairs and abundant offspring are often alluded to.When Ares does appear in myths, he typically faces humiliation. He is well known as the lover of Aphrodite, the goddess of love, who was married to Hephaestus, god of craftsmanship. The most famous story related to Ares and Aphrodite shows them exposed to ridicule through the wronged husband's clever device.
