Clarembald of Arras has mostly been thought of as a disciple whose main contribution to intellectual life was the handing on of the thought of his master, Thierry of Chartres. In this book, John Fortin argues that Clarembald's works warrant a closer examination in order to properly situate him in the intellectual history. Clarembald's mastery of the thought of Boethius was so appreciated by the abbot and monks of Saint Vincent's Abbey in Laon that they requested of him not a copy of Thierry's gloss on Boethius' De Trinitate, but one of his own composition. Fortin examines Clarembald's works in order to determine his place within the context of the tradition of glosses on theological tractates of Boethius upon two of which Clarembald composed complete glosses, namely De Trinitate and the De Hebdomadibus. Contents: The Life and Career of Clarembald of Arras; The Gloss on Boethius' De Trinitate; The Gloss on Boethius' De Hebdomadibus; Clarembald in Medieval Intellectual History; A Note on Clarembald's Tractatulus; Bibliography, Index.
