Lucifer is another name for Satan. This is because people interpret a passage in the Book of Isaiah of the Bible in a certain way. Lucifer is Latin. It is made of two parts, lux-lucis (light) and ferre (to bring).
There are two mentions of Lucifer in the Latin Vulgate. It is used to refer to the morning star, the planet Venus that appears at dawn: once in 2 Peter 1:19 to translate the Greek word "Φωσφόρος" (Phosphoros), which has exactly the same literal meaning of "Light-Bringer" that "Lucifer" has in Latin; and once in Isaiah 14:12 to translate "הילל" (Hêlēl), which also means "Morning Star".

Lucifer is the Latin name[1] for the "Morning Star", both in prose and poetry, as seen in works by Marcus Terentius Varro (116–27 BC), Cicero (106-43 BC) and other early Latin writers[2]

Cicero wrote:

And Pliny the Elder:

Poets also used the word "Lucifer". Ovid has at least eleven mentions of the Morning Star in his poetry.  Virgil wrote:

And Statius:

Lucifer is the epitome of evil in the Christian religion. Lucifer is believed by some to be Satan's name when he was still an angel, but it is Latin for 'light bringer' and not originally in the Bible. 
The word Lucifer was also used in Latin to mean the "morningstar", the planet Venus, and this word was used in the Latin version of Isaiah 14, where the Hebrew version was speaking to a king of Babylonia.
