The Codex Gigas ("Giant Book"; ) is the largest extant medieval illuminated manuscript in the world, at a length of . Very large illuminated bibles were a typical feature of Romanesque monastic book production, but even within this group, the page-size of the Codex Gigas is noted as exceptional. The manuscript is also known as the Devil's Bible, due to its highly unusual full-page portrait of Satan, and the legend surrounding its creation. The manuscript was created in the early 13th century in the Benedictine monastery of Podlažice in Bohemia, now a region in the modern-day Czech Republic. The manuscript contains the complete Vulgate Bible, as well as other popular works, all written in Latin. Between the Old and New Testaments are a selection of other popular medieval reference works: Josephus's Antiquities of the Jews and De bello iudaico, Isidore of Seville's encyclopedia Etymologiae, the chronicle of Cosmas of Prague (Chronica Boemorum), and medical works: an early version of the Ars medicinae compilation of treatises, and two books by Constantine the African. Eventually finding its way to the imperial library of Rudolf II in Prague, the entire collection was taken as spoils of war by the Swedes in 1648 during the Thirty Years' War, and the manuscript is now preserved at the National Library of Sweden in Stockholm, where it is on display for the general public. Description The codex's bookbinding is wooden boards covered in leather, with ornate metal guards and fittings. At long, wide and thick, it is the largest known medieval manuscript. Weighing , Codex Gigas is composed of 310 leaves of vellum claimed to be made from the skins of 160 donkeys, or perhaps calfskin, covering in total. The manuscript includes illuminations in red, blue, yellow, green and gold. Capital letters at the start of books of the bible and the chronicle are elaborately illuminated in several colours, sometimes taking up most of the page; 57 of these survive. The start of the Book of Genesis is missing. There are also 20 initials with the letters in blue, with vine decoration in red. With the exception of the portraits of the devil, an author portrait of Josephus, and a squirrel perched on top of an initial (f. 110v), the illuminations all display geometrical or plant-based forms, rather than human or animal forms. There are also two images representing Heaven and Earth during the Creation, as blue
