E-Sco (Sevilla) Institución Colombina Libro 063

This manuscript has been updated in the last quarter of the 16th century according to the Tridentine reform. Following the humanistic principles promoted by Trent, the melodies were slightly modified, although generally keeping the main design of the original versions, still visible beneath the erasures and modifications. The setting of the liturgical elements was also forcibly modified; in this case, however, it is quite impossible to see the original layer. Therefore, for the entry "Use" above, we indicate "Roman (post-Tridentine)", and in "Tradition", "Seville (modified according to Roman use)". Front paste-down consists of two fragmentary bifolia from a noted Breviary (15th century), with the Office of the Nativity of Mary. Rear paste-down consists of a fragment, from a Gradual (16th century), with part of the 2nd mode Alleluia "Dies sanctificatus illuxit nobis".
