A History of Masks is a book from The Legend of Zelda: The Minish Cap. As its title implies, it is about masks. A copy of the book can be found at the Royal Hyrule Library, and is situated near the home of the Minish Elder, Librari, serving as a "ladder" of sorts leading to his home. At one point, the book was borrowed by Mayor Hagen, who then forgot to return it. Link must retrieve the book from Mayor Hagen's Lakeside Cabin at Lake Hylia in order to reach Librari.
