"The Cathedral Builders: The Story of a Great Masonic Guild" by Leader Scott is a historical account written in the late 19th century. It explores the significant role of the Comacine Masters, a medieval guild of builders and architects, in the evolution of architecture from the decline of the Roman Empire through to the Renaissance. The book seeks to highlight the major architectural advancements made by this guild and its influence throughout Europe during the dark centuries of art history. At the start of the book, the author introduces the historical context of Italian art and the gap between the ancient classical style and the rise of the Renaissance. Scott emphasizes that the Comacine Masters, based in the region around Lake Como, were instrumental in preserving and developing architectural knowledge during this time. He discusses the guild's origins, its organization, and its importance in various church-building efforts across Italy and beyond, presenting them as the vital link between ancient artistic traditions and the flourishing of Gothic architecture. The opening establishes a framework for examining how these builders adapted their skills and influenced the architectural styles found in different regions, while also serving as a precursor to later chapters that dive deeper into specific historical developments and contributions of the guild.
