And indeed Augustine is a deep well! "_Man shall come to a deep heart!_" he was fond of saying, and those words of the Psalmist might stand for a motto at the head of his works. Traditionary art represents him with his heart in his hand, and the sentiment is true, for "great-hearted" is the epithet which best suits him, and those who use these pages for meditation or spiritual reading will find that whereas S. Thomas teaches how we ought to pray, S. Augustine makes us pray; not in vain had he studied and taught rhetoric for so many years! This likeness between the two great Saints forms the theme of one of the _Responsories_ for the Office for S. Thomas in the Dominican Breviary. It is based on a famous vision. "There appeared to me as I watched in prayer," said Brother Albert of Brescia in his deposition, "two revered personages clothed in wondrous splendour. One of them wore a mitre on his head, the other was clad in the habit of the Friars Preachers. And this latter bore on his head a golden crown; round his neck he wore two rings, one of silver, the other of gold; and on his breast he had an immense precious stone, which filled the church with light. His cloak, too, was sewn with precious stones, and his tunic and his hood were of snowy white. And the one who wore the mitre said to me: 'Brother Albert, why art thou thus filled with wonder? Thy prayers are heard; for--listen: I am Augustine, the Doctor of the Church, and I am sent to thee to tell thee of the doctrine and of the glory of Brother Thomas of Aquin who is here with me. For he is my son; he in all things has followed my doctrine and that of the Apostles, and by his teaching he has illumined the Church of God. This is signified by the precious stones which you see, and especially by the one he carries on his breast, for it signifies the upright intention which he ever had in view in his defence of the faith and which he showed in his words. These precious stones, then, and especially that great one, signify the many books and works that he wrote, and they show that he is equal to me in glory save only that in the aureola of Virginity he surpasseth me.'"[21]
