This manuscript, which consists of only 28 leaves and which contains a part of a missal for the Ambrosian Rite, comes from the Oratory of St. Bernardino in Faido (Ticino); under the patronage of the Varesi family, this chapel was newly consecrated in the 15th century (probably 1459). The manuscript was donated to the Oratory by the Varesi family, possibly for this occasion, in order to allow the celebration of the Holy Mass. A quire containing the mass for the patron saint St. Bernardino (20-25) was added to the first quires (1-12, 16-19), as well as the loose leaf with two miniatures representing the Maiestas domini and the crucifixion. The script, a Gothic rotunda of the Italian type, contrasts with the miniatures which show a certain relationship to contemporaneous colored engravings of German origin. (ber)
