This is one of the books that changed science. For the first time Linnaeus’s Fauna Suecica now meets its audience in a modern translation. Published in Latin in 1761 (expanded from the 1746 edition) it is a seminal work that helped to establish the foundation for the classification of modern species. It systematically categorises and morphologically describes 2,328 Swedish animal species – a journey from man to earthworm, revealing their habits, environments, and historical context. It is a window into the mind of a scientific pioneer.
