(attr. Ambrose of Milan) 1.
O lux beata Trinitas,
Et principalis unitas,
Jam sol recedat igneus,
Infunde lumen cordibus. 2.
Te mane laudum carmine,
Te deprecemur vespere:
Te nostra supplex gloria
Per cuncta laudet sæcula. 3.
Deo Patri sit gloria,
Ejusque soli Filio,
Cum Spiritu Paraclito,
Et nunc et in perpetuum.

(tr. John Mason Neale) 1.
O Trinity of blessed light,
O Unity of princely might,
The fiery sun now goes his way;
Shed Thou within our hearts Thy ray. 2.
To Thee our morning song of praise,
To Thee our evening prayer we raise;
Thy glory suppliant we adore
Forever and forevermore. 3.
All laud to God the Father be;
All praise, Eternal Son, to Thee;
All glory, as is ever meet,
To God the Holy Paraclete.
