The Rohonc Code is a valuable guide for how to approach an old unsolved cipher. Historians will benefit from learning some of the mathematical approaches that Lang describes, while mathematicians will benefit from Lang's detailing of how he pursued potential historical leads. -Craig P. Bauer, author of Unsolved! The History and Mystery of the World's Greatest Ciphers from Ancient Egypt to Online Secret Societies This is solid historical research, yet written in a style to make the reader want to read on. . . . Throughout this enthralling exploration, Lang examines the possibilities that the document might be an artificial language or a cypher or perhaps a shorthand system of some kind. -Marcus Williamson, Fortean Times
