Greek personification of the morning star — the planet Venus when visible before sunrise. Son of the Titan Astraeus and Eos; sibling of the four winds and of Hesperus the evening-star (the same celestial body, recognized from at least Pythagoras). Father of Ceyx by an unnamed mortal mother. The Roman counterpart Lucifer ("light-bearer") translates the Greek directly; the modern association of the name with the Christian devil-tradition derives from Isaiah 14:12 "How art thou fallen, O Lucifer" via the Vulgate and is unrelated to the Greek figure.
