Ares is known as the god of war, with Athena. Athena, however,
was goddess of strategy and tactics; Ares was god o the battle
and, as in battle, he was unpredictable and not to
be trusted. Aphrodite loved him (and the two of them were
tricked by her husband, Hephaestus), but none of the other
gods did; they knew he would change allegiances as quickly
as the tide on a battlefield could change.
As noted in the Hephaestus story, he and Aphrodite were trapped
and shamed in front of the
other Gods when Hephaestus caught them together (Aphrodite
was married to Hephaestus).
Ares is usually shown in armor and with weapons. He had two
children, Deimos (Fear) and
Phobos (Terror), and would often travel the battlefield with
Eris, goddess of discord, and Hades, lord of the underworld.
Sacred to Ares were dogs and vultures, which would feed off
the dead in the battlefield.
