Note 33 — Chapter XV
Reading edition
"The saint had previously attended at the vespertinalis Dominicæ noctis missa, an office equivalent to the nocturnal vigil, and now at the turn of midnight the bell rings for matins, which were celebrated according to ancient custom a little before daybreak."—Reeves. The early bells were struck like gongs, not rung, hence the modern Irish for "ring the bell" is bain an clog, "strike the bell."
