"University Surprised by Hidden Text in Donated Renaissance Astronomy Book"

A donated Renaissance-era astronomy book to the Rochester Institute of Technology may contain a hidden treatise, as it appears to be a palimpsest with erased text underneath. The book, a 15th century version of a work by Johannes de Sacrobosco, is suspected to have an older text beneath its words. Another donated book is a famous work by Nicolaus Copernicus from 1543, which postulates that the sun is the center of the universe. The university plans to use imaging science students to decipher the erased words and study the books for advanced work and research.
