Architectura militaris nova et aucta, oder, Newe vermehrte Fortification von regular Vestungen, von irregular Vestungen vnd Aussen wercken, von Praxi offensiva vnd defensiva : auff die neweste Niederländische Praxin gerichtet vnd beschrieben
Adam Freitag's 1665 Amsterdam treatise on military fortification, published by Daniel Elzevir in German, sets out the star-shaped bastioned plans and earthwork designs of Dutch practice for military engineers and siege officers. The plates show ground plans of angled bastions, ravelins and moats, with fold-out diagrams of stone and earth profiles, all drawn in fine engraved line with lettered reference points and scale bars that a designer might borrow for geometric, star-pattern or rampart motifs.
