A hymnal is a collection of the hymns to be sung at the different hours of the liturgical prayer (divine office). Such a collection can autonomously make up a self-dependent book or it can be part of such larger books as a breviary or, exceptionally, an antiphonal. The hymnal of Moggio mainly exhibits the transalpine hymnody tradition that is enriched by such local contributions as the hymn for the Saints Hermagoras and Fortunatus Aeterne deus solio or loans from the Italic tradition, such as the Hymn to St. Vitus Alma beati martyris Viti. Written by an Italian hand, the codex was kept at San Gallo’s Abbey in Moggio, as it is shown by the initial owner’s notice. Some hymns confirm the monastic drawing out of the book. Though a good fifty pieces of more than 130 chants are shared with the Aquileian hymnal, as it is witnessed by the ms. Gorizia B, this codex radically strays from it. With this regard a rubric of the Gorizia codex (f. 98r) once more underlines the difference between the monastic tradition, albeit of a Friulian area, and the Aquileian ecclesiastical tradition: In septuagesima (…) In quibusdam ecclesiis cantatur hymnus (!) Cantemus cuncti, sed Aquilegiensis ecclesia eo non utitur.
