"Similar in design and use to the girdle books of medieval Europe, a rare Arabian saddle book consists of separate pages of the Koran protected within four, nested, leather cases. Hung from the rider’s neck or strapped on his mount’s saddle, scripture was always near at hand. Easy access to the holy book was vital to the faithful, who believed that answers to all of life’s problems resided within the Koran." — The Smithsonian Book of Books
