Aslan is the central lion character in C.S. Lewis’s Narnia books. He appears throughout The Chronicles of Narnia as Narnia’s creator, king, and principal moral authority.
Aslan first appears to readers in The Lion, the Witch and the Wardrobe, where the Pevensie children hear about him before meeting him. His return is associated with the end of the White Witch’s winter and the restoration of Narnia. He is powerful but is not portrayed as merely a conventional human monarch.
Lewis’s Christian beliefs strongly inform Aslan’s role, especially in scenes involving sacrifice, death, and resurrection. Lewis did not present the character as a simple one-to-one retelling of every detail of Jesus’s life; instead, Aslan embodies the story’s imaginative presentation of Christian themes within another world.
Other major Narnian characters have narrower roles. Mr. Tumnus is a faun, Puddleglum is a marsh-wiggle, and Reepicheep is a mouse. None occupies the series-wide position held by Aslan.
