For centuries, writers, artists, and philosophers have attempted to assign a physical image to Lucifer. Most artists have traditionally pictured him as a beast of sorts. Over time, the caricature of Lucifer has taken on many dimensions- many created for shock and awe value as elders told stories to their children or Hollywood directors vied to make the scariest horror film. In Christianity, followers believe that Lucifer was a fallen angel who rebelled against God and was cast unto the earth where he appeared to Eve in the form of a serpent. Most modern Christians who reject the literal story of Adam and Eve believe that Lucifer is a metaphor for all that is evil, and that he promotes lies and deceit from within our souls. In Eastern Orthodox Christianity, Satan is one of humanity's three enemies, along with sin and death. While most contemporary religions believe that the devil is more metaphorical, he has appeared in countless works of classical art and can be seen riding on horseback, falling from the sky, or emerging from thin air. In most of the stories, Lucifer appears when a person is at their weakest moment and open to temptation. While I can't say that I know the answer personally, I do believe that he comes in many forms. I believe that he comes in the physical form of our greatest weakness- whether that's the temptation to cheat on a spouse, the temptation to turn to drugs, alcohol, or gambling, the temptation to rob someone because he has appeared in the form of greed, or temptations far darker and worse than we could ever imagine. In Lucifer's Son, the first book in the Temptation Chronicles, seemingly ordinary people do awful things when tempted by the son of the darkest forces imaginable.
