The tome consists of haikus. Some were spread throughout the game—written on walls and repeated by owls. The book is read three-dimensionally, using a letter from each page in this order: 15263748. The text isn't rotated, and the translation starts in the upper-right corner and moves downwards. The decyphering technique is described at GameFAQs.
