substituting for the lost name of "matins" or variants such as laudes matutinae (morning praises) and matutini hymni (morning hymns). An early instance of the application of the named "matins" to the vigil office is that of the Council of Tours in 567, which spoke of ad matutinum sex antiphonae. The Rule of Saint Benedict clearly distinguished matins as the nighttime hour, to which he applied Psalm 118/119:62, "At midnight I rise to praise you, because of your righteous rules". The word vigil also took on a different meaning: not only a prayerful night watch before a religious feast, but the day before a feast. Monastic matins The canonical hour began with the versicles, "O God, come to my assistance; O Lord, make haste to help me" and "O Lord, Thou wilt open my lips, and my mouth shall declare Thy praise" (the latter said three times) followed by Psalm 3 and Psalm 94/95 (the Invitatory). The Invitatory was to be recited slowly out of consideration for any late-arriving monk, since anyone appearing after its conclusion was punished by having to stand in a place apart. After this a hymn was sung. Next came two sets of six psalms followed by readings. (Such sets would later be called nocturns.) The first set was of six psalms followed by three readings from the Old or New Testaments or from Church Fathers. Each reading was followed by a responsory. The second set of six psalms was followed by a passage from the Apostle Paul recited by heart and by some prayers. The Night Office then concluded with a versicle and a litany that began with Kyrie eleison. Since summer nights are shorter, from Easter to October a single passage from the Old Testament, recited by heart, took the place of the three readings used during the rest of the year. On Sundays, the office was longer, and therefore began a little earlier. Each set of six psalms was followed by four readings instead of three after the first set and a single recitation by heart after the second set. Then three canticles taken from Old Testament books other than the Psalms were recited, followed by four readings from the New Testament, the singing of the Te Deum, and a reading by the abbot from the Gospels, after which another hymn was sung.
