Lucifer (UK: LOO-si-fər; US: ; 'light-bringer') is a Latin name for the planet Venus in its morning appearances, and is often used for mythological and religious figures associated with the planet. Due to the unique movements and discontinuous appearances of Venus in the sky, mythology surrounding these figures often involved a fall from the heavens to earth or the underworld. Interpretations of a similar term in the Hebrew Bible, translated in the King James Version as "Lucifer", led to a Christian tradition of applying the name Lucifer, and its associated stories of a fall from heaven, to Satan. Most modern scholarship regards these interpretations as questionable, and translates the term in the relevant Bible passage (Isaiah 14:12) as "morning star" or "shining one" rather than as a proper name, "Lucifer".
As a name for the Devil, the more common meaning in English, "Lucifer" is the rendering of the Hebrew word הֵילֵל (transliteration: hêylêl; pronunciation: hay-lale) in Isaiah (Isaiah 14:12) given in the King James Version of the Bible. The translators of this version took the word from the Latin Vulgate, which translated הֵילֵל by the Latin word lucifer (uncapitalized), meaning "the morning star, the planet Venus", or, as an adjective, "light-bringing".
As a name for the planet in its morning aspect, "Lucifer" is a proper name and is capitalized in English. In Greco-Roman civilization, it was often personified and considered a god and in some versions considered a son of Aurora (the Dawn).
