Latin Metus, the personification of fear, is described as a son of Ares and Cythereia, a brother of Deimos, and is one of the ordinary companions of Ares. (Hom. Il. xi. 37, xiii. 299, xv. 119; Hes. Theog. 934.) Phobus was represented on the shield of Agamemnon, on the chest of Cypselus, with the head of a lion. (Paus. v. 19. § 1.)
