Adam of Saint Victor (died 1146) was a prolific poet and composer of Latin hymns and sequences. He is believed to have sparked the expansion of the poetic and musical repertoire in the Notre Dame school with his strongly rhythmic and imagery-filled poetry.The first reference to him is from 1098, in the archives of Notre Dame Cathedral, where he was first a subdeacon, and later a precentor. He left the cathedral for the Abbey of Saint Victor around 1133, probably because of his attempts at imposing the Rule of St Augustine at the cathedral.Adam probably had contact with a number of important theologians, poets, and musicians of his day, including Peter Abelard and Hugh of St Victor, and he may have taught Albertus Parisiensis.Adam of St Victor’ surviving works are sequences for liturgical use, not theological treatises. Around 47 sequences by Adam survive. In a practice that developed from the ninth century onwards, these are poems composed to be sung during the mass, between the Alleluia and the gospel reading. The sequence therefore bridges the Old Testament or epistle readings and the gospel, both literarily and musically.
