Weirder and weirder...
Carroll's sequel to Alice's Adventures In Wonderland is undoubtedly the final opus magnum of crazy, out of this world, acid trippy like, goodness. Many of the characters get intermixed into later retellings of the story, like the Tweedle twins, the Walrus, and his sidekick Jesus, but technically they belong to this later continuation. While Alice used playing cards as a theme, Looking-Glass uses chess, and as you have probably already observed, both "games" have strong connections to mathematical theory and equations, as well as supernatural connotations, and perhaps some hidden meanings. As with everything Carroll...it simply gets curiouser and curiouser...
Incidentally, there was a part of the story cut out
by Carroll, or suppressed, involving a wasp wearing a wig (the anti-thesis of a
bee in your bonnet), and can be found here should you wish to complete your
reading, in full, of this most intriguing text...and unlike Alice's Adventures In Wonderland, Lewis Carroll's Through the Looking-Glass can be seen
and read...from a first edition copy no less...
