The oldest scientific manuscript in the National Library the volume contains various Latin texts on astronomy. The volume, written in Caroline minuscule, consists of two sections, the first (ff. 1-26) copied c. 1000, in the Limoges area of France, probably in the milieu of Adémar de Chabannes (989-1034), whilst the second (ff. 27-50), from a scriptorium in the same region, may be dated c. 1150.
