E-Sco (Sevilla) Institución Colombina Libro 52

This manuscript has been updated in the last quarter of the 16t century, in the wake of 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 entries "Tradition" and "Use" above, we indicate "Roman (post-Tridentine)".
Front and back flyleaves are fragments from a Sanctoral antiphoner (c. 1500), containing the Invitatory antiphon, hymn and first antiphon of the Matins office for Saints Fabian and Sebastian.
