All of these factors could potentially contribute to the deterioration of a fifteenth-century book. However, the most common cause of deterioration to a book from that time period would likely be mold. Mold can thrive in environments with high humidity, and if a book is stored in a damp or moist area, it increases the likelihood of mold growth. Mold can damage and degrade the paper, ink, leather covers, and bindings of the book, ultimately leading to its deterioration.
