A Note about the Order of the Chronicles
The order in which Lewis published the Narnia Chronicles is:
The Lion, the Witch and the Wardrobe (1950)
Prince Caspian (1951)
The Voyage of the “Dawn Treader” (1952)
The Silver Chair (1953)
The Horse and His Boy (1954)
The Magician’s Nephew (1955)
The Last Battle (1956)
Most Lewis scholars agree that The Lion, the Witch and the Wardrobe should be read first because it was written first and published first and takes special care to introduce the character of Aslan. The Magician’s Nephew should therefore not be read first, even though it deals with an earlier stage in Narnian history. It is better to read it as a flashback or a prequel.
