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.
