The Etymologiae of Isidore of Seville. The manuscript is not illustrated.

Encyclopedia with emphasis on word origins, arranged by subject. The manuscript follows the standard division into 20 books, except that Book 3, on mathematics, music, and astronomy, is divided into Books 3 and 4, giving the manuscript a total of 21 books. Additional astronomical material, probably from Bede's De temporum ratione, appears at the end of Book 21 (f. 178v-183v), with the running head of Book 21 continuing to the end of the manuscript.
