Manuscript magazines are documents written by hand before the invention of printing. Manuscripts were not defined by their content and could include writing, maps, illustrations. In India, palm leaf manuscripts were commonly used from ancient times until the 19th century. Paper spread from China via the Islamic world to Europe in the 15th century and replaced parchment. Modern variations include film/theater scripts and screenplays. Historical genres included Bibles which were widely studied in the Middle Ages, and Books of Hours which contained prayers and were popular devotional texts.
