'flight, fright',[1] pronounced [pʰóbos], Latin: Phobus) is the god and personification of fear and panic in Greek mythology.

[citation needed] In the Iliad, he accompanied his father into battle along with the goddess Eris (discord) and his brother Deimos (Dread).

[8] According to Stesichorus, Ares's son, Kyknos, "...beheaded strangers who came along in order to build a temple to Phobos (fear) from the skulls.

And circled in the midst of all was the blank-eyed face of the Gorgo (Gorgon) with her stare of horror, and Deimos (Dread) was inscribed upon it, and Phobos (Fear).

119 ff:"So he [Ares] spoke, and ordered Deimos (Dread) and Phobos (Fear) to harness his horses, and himself got into his shining armour."

According to Plutarch, Alexander the Great offered sacrifices to Phobos on the eve of the Battle of Gaugamela (in all probability asking for Darius to be filled with fear).
