Peribologia, oder, Bericht Wilhelmi Dilichy Hist. von Vestungsgebewen vieler Orter : vermehrett wie auch mit gebürenden Grundt vnd Auffrissen versehen vnd publisirett durch Johannem Wilhelmum Dilichium ..
Peribologia is a 1640 German treatise on fortification published in Frankfurt am Main by Anthonio Hummen, compiled by Wilhelm Dilich and Johann Wilhelm Dilich with Sebastian Furck, aimed at military engineers and builders of town defences. Its numbered plates show plans of star-shaped bastioned fortresses, with angled ramparts, moats and glacis drawn in fine line hatching. A designer could take from them the geometry of zigzag star forts and the crisp engraved shading used to suggest depth in plans.
