Before Study Prayer in English
O INFINITE Creator, who in the riches of Thy wisdom didst appoint three hierarchies of Angels and didst set them in wondrous order over the highest heavens, and who didst apportion the elements of the world most wisely:
Do Thou, who art in truth the fountain of light and wisdom, deign to shed upon the darkness of my understanding the rays of Thine infinite brightness, and remove far from me the twofold darkness in which I was born, namely, sin and ignorance.
Do Thou, who givest speech to the tongues of little children, instruct my tongue and pour into my lips the grace of Thy benediction.
Give me keenness of apprehension, capacity for remembering, method and ease in learning, insight-in interpretation, and copious eloquence in speech.
Instruct my beginning, direct my progress, and set Thy seal upon the finished work, Thou, who art true God and true Man, who livest and reignest world without end. Amen.
Oratio ante studium
CREATOR ineffabilis, qui de thesauris sapientiae tuae tres Angelorum hierarchias designasti et eas super caelum empyreum miro ordine collocasti atque universi partes elegantissime distribuisti:
Tu, inquam, qui verus fons luminis et sapientiae diceris ac supereminens principium, infundere digneris super intellectus mei tenebras tuae radium claritatis, duplices, in quibus natus sum, a me removens tenebras, peccatum scilicet et ignorantiam.
Tu, qui linguas infantium facis disertas, linguam meam erudias atque in labiis meis gratiam tuae benedictionis infundas.
Da mihi intelligendi acumen, retinendi capacitatem, addiscendi modum et facilitatem, interpretandi subtilitatem, loquendi gratiam copiosam. Ingressum instruas, progressum dirigas, egressum compleas.
Tu, qui es verus Deus et homo, qui vivis et regnas in saecula saeculorum. Amen.
This prayer dating from the 13th Century and composed by the great St Thomas Aquinas used to be part of the Raccolta of 1923 until the changes of Vatican II.
