After beginning the digital library of historic environmental regulation with works from the last few hundred years, we return in time this week to the fourteenth century and the Tractatus de fluminibus seu Tyberiadis (1355, 1576 model (provide of the images on this put up) proper right here) of the nice medieval Italian jurist Bartolus of Saxoferrato.

I instructed him to spare me from illustrating approved points with geometrical diagrams, since had been I to do that, there might be many further scoffers than supporters.
