This monograph offers a dual contribution: a concise yet comprehensive presentation of the lesser-known works of Guillaume Budé (1468–1540), the most renowned French humanist, and an invitation to rediscover the treasures of Renaissance scholarly literature. An avid reader of Latin and Greek classics, Budé mastered a vast range of authors and technical fields, from Homer to Isidore of Seville, medicine, architecture, rural economics, and law. The book immerses readers in Budé’s extensive world of research, revealing the foundations of his groundbreaking works.
