León palimpsest
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 following Jerome's Vulgate in others. The codex is a palimpsest.
From its location in Léon, 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 Basilica of San Isidoro, León (Codex Gothicus Legionensis, or 91, 92 and 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 of Léon (number 193 in the Beuron system).
