Lucifer is commonly known as a figure in Christian theology representing the Devil or Satan, originally an archangel who fell from Heaven due to pride and rebellion against God

. The name "Lucifer" means "light-bringer" and is associated with the morning star, the planet Venus, personified in classical mythology as a male figure bearing a torch

. In Christian tradition, Lucifer was a magnificent angel created perfect but became prideful because of his beauty and status, leading him to desire God's honor for himself. This pride caused his fall from grace, and he was cast out of Heaven, becoming the ruler of Hell

. Despite being cast down, some scriptures suggest he retained limited access to Heaven

. In folklore and some modern pagan traditions, Lucifer has been depicted differently. For instance, in Charles Godfrey Leland's Aradia, or the Gospel of the Witches , Lucifer is portrayed as a god of light and the brother and consort of the goddess Diana, symbolizing the planet Venus and celestial light

. In popular culture, Lucifer is often reimagined. A notable example is the character Lucifer Morningstar from the TV series Lucifer , based on a DC Comics character. This version is a fallen archangel who abandons his Hell duties to live on Earth, running a nightclub and working as a police consultant, displaying complex personality traits and supernatural abilities

. In summary, Lucifer is primarily known as the fallen angel who became Satan in Christian theology, symbolizing pride and rebellion against God, but the figure has varied interpretations in mythology, folklore, and modern media.
