Lucifer
Lucifer is the Latin name for the morning appearances of the planet Venus. It corresponds to the Greek names Phosphorus Φωσφόρος, "light-bringer", and Eosphorus Ἑωσφόρος, "dawn-bringer". The entity's Latin name was subsequently absorbed into Christianity as a name for the devil.
As a name for the Devil in Christian theology, the more common meaning in English, "Lucifer" is the rendering of the Hebrew word הֵילֵל, hêlēl, (pronunciation: hay-lale)[1] in Isaiah[2] given in the King James Version of the Bible. The translators of this version took the word from the Latin Vulgate,[3] which translated הֵילֵל by the Latin word lucifer (uncapitalized),[4][5] meaning "the morning star", "the planet Venus", or, as an adjective, "light-bringing".[6]
As a name for the planet in its morning aspect, "Lucifer" (Light-Bringer) is a proper noun and is capitalized in English. In Greco-Roman civilization, it was often personified and considered a god[7] and in some versions considered a son of Aurora (the Dawn).[8] A similar name used by the Roman poet Catullus for the planet in its evening aspect is "Noctifer" (Night-Bringer).[9]
