“NOX ET TENEBRAE ET NUBILA.” Hymn at Lauds in the Wednesday Office.
Drawn from the second longest hymn in Prudentius’s *Cathemerinon*, it is one vast outburst of joy, for just as the advancing daylight causes the darkness of night and its shadows to vanish, so before Christ the spiritual darkness vanishes; and just as in the light of the sun all creation is revealed in its beauty, so, illumined by the “Sun who enlightens every man who comes into this world” (Jn 1:9), man can gaze into the depths of his being and purify it by dispelling every darkness and shadow.
