The Abbey of St. Victor, from which the great Latin hymnologist takes his name, and which, originally, was in the suburbs of Paris, was later on absorbed into the city itself, as she enlarged her borders, was celebrated, especially in the twelfth century, as a school of theology. Probably no other religious foundation could boast of such a brilliant triad of doctors of divinity, as the one that graced this Abbey during that century in the persons of Hugh of St. Victor, known to his generation as the "Second Augustine;" his pupil, Richard of St. Victor, named Alter Augustine; and Adam of St. Victor, the author of the Sequences in these volumes, who, as will be apparent to the most cursory reader was even deeply versed in the learning of the school to which he belonged.
