By St. Thomas Aquinas

O Mary, Mother of fair love, of fear, of knowledge, and of holy hope, by whose loving care and intercession many otherwise poor in intellect have wonderfully advanced in knowledge and holiness, I choose you as the guide and patroness of my studies; and I humbly implore, through the deep tenderness of your maternal love, and especially through the eternal Wisdom who deigned to take our flesh from you and who gifted you beyond all the saints with heavenly light, that you would obtain for me, by your intercession, the grace of the Holy Spirit that I may be able to grasp with strong intellect, retain in memory, proclaim by word and deed, and teach others all things which bring honor to you and to your Son, and which for me and for others are salutary for eternal life. Amen.
