From an original 1863 Louis le Breton's illustration

Lucifer, "bringing light", derived from Latin lux "light" and ferre "to bring". In Latin this name originally referred to the morning star, Venus, but later became associated with the chief angel who rebelled against God's rule in heaven (see Isaiah 14:12). In later literature, such as the Divine Comedy (1321) by Dante and Paradise Lost (1667) by John Milton, Lucifer became associated with Satan himself.

According to some magicians, Lucifer rules over the East and commands the Europeans and the Asians. He is often referred to as the king of hell, and is superior to Satan according to some demonologists. He was evoked on Monday in the middle of a circle which contained his name and remained content when a mouse or venison-bit was offered to him. One says he is facetious, and that he often pulls witches off brooms on their journey to the Sabbath and gives them a ride on his shoulders.
