The León Palimpsest, designated l or 67 (in the Beuron system), is a 7th-century Latin manuscript pandect of the Christian Bible conserved in the cathedral of León, Spain. The text, written on vellum, is in a fragmentary condition. In some parts it represents the Old Latin version, while follows Jerome's Vulgate in others. The codex is a palimpsest. From its location in León, this palimpsest is sometimes referred to as the Codex Legionensis; but this name is more commonly applied to the 10th-century Vulgate Bible at the Basílica de San Isidoro, León (133 in the Beuron system). Nor should the León palimpsest be confused with another 10th-century pandect in León, of which the second volume is conserved in the cathedral archive and is number 193 in the Beuron system.
