Aslan's Other Name

C. S. Lewis to 11-year-old Hila Newman, from New York:

As to Aslan's other name, well I want you to guess. Has there never been anyone is this world who (1) Arrived at the same time as Father Christmas. (2) Said he was the son of the Great Emperor. (3) Gave himself up for someone else's fault to be jeered at and killed by wicked people. (4) Came to life again. (5) Is sometimes spoken of as a Lamb (see the end of the Dawn Treader). Don't you really know His name in this world. Think it over and let me know your answer!
