The Junius manuscript is one of the four major codices of Old English literature. Written in the 10th century, it contains poetry dealing with Biblical subjects in Old English, the vernacular language of Anglo-Saxon England. Modern editors have determined that the manuscript is made of four poems, to which they have given the titles Genesis, Exodus, Daniel, and Christ and Satan. The identity of their author is unknown. For a long time, scholars believed them to be the work of Cædmon, accordingly calling the book the Cædmon manuscript. This theory has been discarded due to the significant differences between the poems. The manuscript owes its current designation to the Anglo-Dutch scholar Franciscus Junius, who was the first to edit its contents and who bequeathed it to Oxford University. It is kept in the Bodleian Library under shelfmark MS Junius 11. Name and date The codex now referred to as the "Junius manuscript" was formerly called the "Cædmon manuscript" after an early theory that the poems it contains were the work of Cædmon; the theory is no longer considered credible, therefore the manuscript it is commonly referred to either by its Bodleian Library shelf mark "MS Junius 11", or more casually as "the Junius manuscript" or "Codex Junius". 'Junius' in these is Franciscus Junius, who published the first edition of its contents in 1655. It has been established on palaeographical grounds that compilation of the manuscript began c. AD 1000. Recent work has suggested an earlier, narrow window for the likely compilation date to 960-1000 for Liber I and shortly thereafter for Liber II, based on an integrated dating of the text, paleography, and illustrations. The compilation was in two stages: Liber I contains the poems Genesis, Exodus, and Daniel, and was the work of a single scribe. Liber II contains the poem Christ and Satan. The manuscript contains numerous illustrations that are an example of the Winchester style of drawing, typical of the period and region; it appears that two illustrators worked independently on the manuscript. The first scribe left spaces in the text for other illustrations which were never completed. Illustrations The manuscript is partly illustrated with a series of line drawings depicting the events in the text. From spaces left by the scribes, it appears that it was intended that the manuscript be fully illustrated; in the event, the work was left unfinished after only about a third
