Te lucis ante terminum

The hymn Te lucis as written out in a Spanish manuscript (c. 1625). The wording pro tua clementia (instead of solita clementia) reflects the classicizing revisions of Pope Urban VIII. The original Latin version has been restored in the post-Vatican II texts.

Te lucis ante terminum ('To Thee before the close of day') is an old Latin hymn in long metre. It is the hymn at Compline in the Roman Breviary.
