Book excerpt: The late eighteenth century and subsequent Napoleonic Era witnessed a turning point in the establishment of agricultural science as a well-defined discipline in northern Italy. In this book, Martino Lorenzo Fagnani traces these developments by reviewing the correspondence of naturalists and agriculturists as well as the research plans of universities, academies, societies, institutes, and governments. He explores the establishment of a broad knowledge network encompassing all of Europe while also investigating the reasons behind the exchange of seeds, the establishment of spaces for experimentation such as scientific gardens and experimental fields, and the organization of specialized journals and monographs. This work represents an important contribution to the historiography of Italian agricultural science, filling a significant gap in our knowledge of related developments.
