This essay delves into the work of Nicolas Jenson, one of the most influential printers of the 15th century. He's renowned for creating a Roman typeface, the so called "Jenson Roman" that has shaped much of modern typography. The volume stands out for its use of numerous high-quality illustrations, which allow the reader to visually follow the technical analyses and fully understand the significance of this still little-known artisan's work within his historical context. The images help verify the accuracy of the observations and provide a tangible visual reference for the letters created by the printer. Many typographers used the Jenson Roman as a model at the beginning of the 20th century, a period of significant renewal in the art of printing. Despite his notable impact on typography, Jenson's contribution has yet to be fully recognized within the historical landscape. This book aims to address this gap, offering new bibliographical insights and an unprecedented photographic analysis that reveals previously unexplored aspects of his work. The work not only explores Jenson's career but also the techniques he employed to create his typefaces. In particular, it examines the origins and evolution of his letters, providing a clear view of his creative process and technical approach. The book also highlights Jenson's influence on later engravers such as Francesco Griffo and Claude Garamont, who adopted many of his design choices, establishing the standards for lowercase Roman typefaces still in use today. In summary, this volume offers a comprehensive analysis of Jenson's contribution to typography. It takes a historical perspective enriched by new discoveries and careful visual analysis. The author, Riccardo Olocco, is known for his in-depth research on Roman typefaces and the typographic techniques used in past centuries. He combines a rigorous academic approach with close attention to practical and technical details.
