The Story of Phobos
Phobos was the god of fear and panic, a son of Ares and Aphrodite. His brother Deimos was the god of dread, and the two rode into battle with their father. Hesiod says they drove the ranks of warriors into rout in chilling war.
In the Iliad, Phobos spreads fear among the fighters, and when Ares learned that his son Ascalaphus had been killed, he called for Phobos and Deimos to yoke his horses. His terrifying face was painted on warriors' shields, as on the shield of Heracles described in an ancient poem. The Spartans were said to have a shrine to him, honoring the fear that broke enemy lines.
The word phobia, an intense fear, comes from his name. When the astronomer Asaph Hall discovered the two moons of Mars in 1877, he named them Phobos and Deimos, after the sons of Ares, whom the Romans called Mars. Phobos, the larger moon, still circles the red planet.
