The Trinity and Creation are central themes in the theology of the Augustinian Canons of the Abbey of St. Victor during the twelfth century, when it flourished. In this volume, for the first time three of the most important Victorine theological works are introduced in complete English translations: On the Three Days, by Hugh of St. Victor; Hugh’s Sentences on Divinity; On the Trinity, by Richard of St. Victor. This volume also includes two of Adam of St. Victor’s sequences in praise of the Trinity.
