Is The Chronicles of Narnia series a Christian allegory?

Many readers interpret C.S. Lewis’s classic children’s fantasy series The Chronicles of Narnia (1950–56) to be a Christian allegory. However, Lewis said that he did not intend the books to be allegories. Instead, he preferred to call them “supposals.” He once wrote to a fifth-grade class in Maryland, “Let us suppose that there were a land like Narnia and that the Son of God, as He became a Man in our world, became a Lion there, and then imagine what would happen.” Although some episodes echo biblical stories, including Aslan (the lion) dying in the human child Edmund’s place, Lewis meant the books to serve as a new creation story and to stand on their own as adventure-filled stories.
