~St. Thomas Aquinas: Exposition In Psalmos, Prologue.
Sanctorale. France, ca.1275
Antiphonal: "The antiphonal (antiphonarium), or antiphonary, contains the music, e.g., hymns, responsories, versicles, responses, psalms, etc. (think gregorian chant here) sung by the clergy or choir during the mass or the Liturgy of the Hours. The first mention of an official antiphonary is from Pope Gregory I in the seventh century and the oldest extant manuscripts are from the ninth century. They are still in use today." (source: J. Hughes)
