(Ἵμερος), the personification of longing love, is first mentioned by Hesiod (Hes. Th. 201), where he and Eros appear as the companions of Aphrodite. He is sometimes seen in works of art representing erotic circles; and in the temple of Aphrodite at Megara, he was represented by Scopas, together with Eros and Pothus. (Paus. 1.43.6.)
