Ambrosian hymns
The Ambrosian hymns are a collection of early hymns of the Latin liturgical rites, whose core of four hymns were by Ambrose of Milan in the 4th century. The hymns of this core were enriched with another eleven to form the Old Hymnal, which spread from the Ambrosian Rite of Milan throughout Lombard Italy, Visigothic Spain, Anglo-Saxon England and the Frankish Empire during the early medieval period (6th to 8th centuries); in this context, therefore, the term “Ambrosian” does not imply authorship by Ambrose himself, to whom only four hymns are attributed with certainty, but includes all Latin hymns composed in the style of the Old Hymnal.
