In Greek mythology, Hesperus (/ˈhɛspərəs/; Ancient Greek: Ἕσπερος, romanized: Hésperos) is the Evening Star, the planet Venus in the evening. A son of the dawn goddess Eos (Roman Aurora), he is the half-brother of her other son, Phosphorus (also called Eosphorus; the "Morning Star"). Hesperus' Roman equivalent is Vesper (cf. "evening", "supper", "evening star", "west"). By one account, Hesperus' father was Cephalus, a mortal, while Phosphorus was the star god Astraeus. Other sources, however, state that Hesperus was the brother of Atlas, and thus the son of Iapetus.
