Though Adam of St. Victor was one of the most prominent and prolific Latin hymnists of the Middle Ages, little is known of him. Writers nearest his time describe him as Brito, possibly indicating a native of Britain or Brittany.
All that is certain is that around 1130, after being educated in Paris, he became, at quite a young age, a monk in the Abbey of St. Victor, a well known school of theology on the outskirts of Paris.
He spent the rest of his life there, dying some time between 1172 and 1192.
