Lucifer

Lucifer is derived from the latin term lucem ferre, which means bringer, or bearer, of light. It has become a synonym with Satan in some Christian texts, including some translations of the Bible. He is a deity in the Voodoo religions.

However, Lucifer is only mentioned one place in some translation of the Bible, in Isaiah 14:12, and only translations based on the Latin translation largely made by St. Jerome in the fourth century.

The hebraic texts refer to Heylel Ben-Shachar, where 'Heylel' is the hebraic word for the planet known as Venus, and Ben-shachar means 'Son of the dawn'. St. Jerome translated Heylel into Lucifer, which was Venus' name at the time.

Isaiah 14 starts out discussing the King of Babylon, and some claim that it is him the reference 'morning star, son of the dawn' refers to. Christian tradition however, claims it to be a reference to the downfall of Satan.
