In Hesiod's Theogony, Deimos is the son of Ares and Cytherea (Aphrodite), and the sibling of Phobos and Harmonia.
[citation needed] In the Iliad, he accompanied his father, Ares, into battle with the Goddess of Discord, Eris, and his brother Phobos (fear).
[6] The poet Antimachus, in a misrepresentation of Homer's account, portrays Deimos and Phobos as the horses of Ares.
[7] In Nonnus' Dionysiaca, Zeus arms Phobos with lightning and Deimos with thunder to frighten Typhon.
[8] Later in the work, Phobos and Deimos act as Ares' charioteers to battle Dionysus during his war against the Indians.
