Thomas Aquinas — Prayer Before Study

Ineffable Creator, who out of the treasures of Thy wisdom hast appointed three hierarchies of Angels and set them in admirable order high above the heavens, and hast disposed the divers portions of the universe in such marvellous array: Thou who art called the True Fountain of Light and supereminent Principle of Wisdom, be pleased to cast a beam of Thy brightness on the darkness of my understanding and dispel from me the double darkness of sin and ignorance in which I was born.
