qui custos es mei,
Me tibi commissum pietate superna;
Hodie illumina, custodi, rege, et guberna.
Angel of God,
my guardian dear,
To whom his love commits me here;
Ever this day be at my side,
To light and guard, to rule and guide.
This prayer, although commonly attributed to St. Anselm, was more likely written by Reginald of Canterbury, a 12th century Benedictine monk. The Latin poem was later added to the works of St. Anselm – I suppose to give it added importance. But it has its own beauty, simplicity and power, no matter who wrote it.
