Francesco Maria Pecchi (1618-1693) was a professor of canon law at Pavia from 1659 to 1687 and Archdeacon of the Cathedral of Pavia, where he is buried. As a result of Italy’s mountainous geography and extensive coastline, the science of training and regulating rivers developed to its highest degree in Italy by the end of the 17th century. It was in this field that Pecchi was to make his name, and in the history of law he is known as the father of modern water legislation as a result of this important treatise on civil and cannon law, together with his other extensive work ‘Tractatus de Servitutibus’ (1689).
The numerous woodcut diagrams and tables illustrating cases of water rights have a beautiful and most appealing naivety. It was reprinted in 1707, and again in 1840 - a testament to its importance and unsurpassed pertinence and scholarship.
