Aslan is the lion at the center of C.S. Lewis’s Narnia books.
Aslan appears throughout The Chronicles of Narnia as a powerful, wise, and benevolent ruler. He is the son of the Emperor-beyond-the-Sea and helps create, guide, and ultimately judge the world of Narnia within the series’ mythology.
The character is widely understood as carrying Christian symbolism, especially through his death and return in The Lion, the Witch and the Wardrobe. Lewis resisted reducing the novels to simple one-to-one allegories, however. He described the stories as imaginative works in which Christian ideas could be experienced through a different world.
Aslan is not the name of a human king or one of the visiting children. Several human characters, including Peter and Caspian, rule parts of Narnia, while Aslan remains its transcendent and foundational figure.
