Lorenzo Valla: The Pioneer of Biblical Philology traces the life and groundbreaking scholarship of one of the Renaissance's most influential humanists. This book explores how Valla's mastery of classical languages and critical methods exposed deep textual corruptions in the Latin Vulgate Bible and famously unmasked the Donation of Constantine as a medieval forgery. By combining linguistic precision with keen historical insight, Valla challenged centuries of unquestioned ecclesiastical authority and reshaped the study of sacred texts. His pioneering approach not only transformed Renaissance humanism and biblical scholarship but also laid the foundations for modern textual criticism and critical inquiry. Through detailed analysis of Valla's methods, key textual corrections, and his profound influence on later scholars like Erasmus and the reformers, this volume reveals the enduring legacy of a scholar whose work revolutionized the pursuit of truth in theology, history, and philology.
