Through a partial critical edition and study of Peter Comestor's lectures, this volume recontextualizes the biblical exegesis of the twelfth-century Latin cathedral schools within the frameworks of the study of ars grammatica, underscoring the importance of the master-disciple relationship in forming medieval exegetical schools of thought.This study critically examines the Latin biblical lectures of Peter Comestor, a twelfth-century scholar based in Paris, focusing on his commentary on the Gospel of Luke and its glossing tradition.The study positions Comestor's lectures among Latin biblical commentaries produced in the cathedral schools of Laon and Paris, a vital intellectual movement shaped by well-known figures such as Anselm of Laon and Peter Lombard, and which provided the foundations for the University of Paris. Recent scholarship has sought to bridge the gap between biblical commentaries and systematic theological treatises by highlighting the shared didactic methodologies between the medieval study of the liberal arts and sacred scripture.This study of Comestor's Luke lectures expands these efforts, underscoring the role of classical philology and liberal arts pedagogy in shaping medieval theological thought. The volume highlights how the cathedral school scholars of northern France approached Christian theology as a work of textual criticism, exploring a wide range of subjects—from geometry to canon law—through biblical interpretation.By tracing these intellectual traditions, the study uncovers the pedagogical practices that informed the understanding of Christian biblical exegesis in the Latin Middle Ages, particularly in the period leading up to the establishment of Europe's first universities and theology faculties.
