The Bobbio Jerome (Milan, Biblioteca Ambrosiana MS S. 45. sup.) is an early seventh-century manuscript copy of the Commentary on Isaiah attributed to St. Jerome. The manuscript has 156 pages and measures 235 by 215 mm. 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 interesting to compare this initial with the few decorated ones in Gregory the Great, Pastoral Care (Troyes, Bibliothèque Municipale, MS 504), from Rome, and about twenty years older.
