E-Sco (Sevilla) Institución Colombina Libro 056

This manuscript has been updated in the last quarter of the 16t 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 entries "Tradition" and "Use" above, we indicate "Roman (post-Tridentine)". The flyleaf of the front cover is a fragment from a Temporal Antiphoner (15th century) with part of the Trinity antiphon "Deum laudemus verum". The flyleaf of the back cover is a bifolio fragment from a Gradual (16th century), which includes the following chants for the fourth week in Lent: Gradual verse "Ut quid domine recessisti", Tract (no music) "Adjuva nos" and the beginning of the Offertory "Benedicite gentes dominum".
