The Rule of Four (2004)
Ian Caldwell / Dustin Thomason
...

Contributed by Vijay Fafat

There is an enigmatic book from the late 15th century called Hypnerotomachia Poliphili, written by an Italian monk, Francesco Colonna (available at gutenberg.org for download). The book chronicles the dream-within-a-dream love adventure of Poliphilo and his object of affection, Polia. The enigma of the book arises from the author’s use of vocabulary from multiple languages and neologisms, which give it an inscrutable, labyrinth-like quality and a suspicion that it contains far more than just the richly illustrated love story.

“The Rule of Four” takes off on this premise that there is a hidden code in the text of Hypnerotomachia; in fact, the entire book is a cipher pointing to a very well-guarded secret. Set on the grounds of Princeton University, “The Rule of Four” shows how two students unlock the mystery. Naturally, the book is full of allusions to cryptography, mathematical patterns, breathless chases, historical and current murders, lost manuscripts, etc. For example,

  • an expert at the mathematical analysis of the Torah plays a role,
  • the sequence 3, 4, 6, 9 is found to unlock one part of the book since “it is the smallest sequence which produces all three harmonies (arithmetic, geometric and harmonic)” [I don’t know what this means].
  • Eratosthenes and his measurement of Earth’s circumference based on the geometry of shadows is discussed when one of the clues requires the students to calculate “the distance between you and the horizon” (the sub-puzzle at this point of the story is about art and perspective drawing).
  • Quote from book: “The most complicated concept he taught me was how to decode a book based on algorithms or ciphers from the text itself. In those cases, the key is built right on. You solve for the cipher, like an equation or a set of instructions, the you use the cipher to unlock the text. The book acually interprets itself.”
The novel is a lot of fun to read and savor.

May 2016: I am experimenting with a new feature which will print a picture of the cover and a link to the Amazon.com page for a work of mathematical fiction when it is available. I hope you find this useful and convenient. In any case, please write to let me know if it is because I would be happy to either get rid of it or improve it if that would be better for you. Thanks! -Alex
