is an early seventh-century manuscript copy of the Commentary on Isaiah attributed to St. Jerome.
It is a palimpsest that previously contained a sixth-century copy of the Gothic translation of the Bible by Ulfilas written in Gothic uncial, with Rustic capitals as a display script.
It is written in black ink and decorated by whorl and cross patterns and pelta motifs.
On page two there is an inscription connecting the manuscript to Atalanus, who was St. Columbanus's successor as abbot of the monastery at Bobbio.
This initial can be compared with the few decorated ones in Gregory the Great, Pastoral Care (Troyes, Bibliothèque Municipale, MS 504), from Rome, and about twenty years older.
