Nvovo ragionamento del fabricare le fortezze : si per prattica, come per theorica ; oue diffusamente si mostra tutto quello ch'a tal scientia si appartiene
Girolamo Cataneo's 1571 Italian treatise on fortress construction, printed in Brescia for military engineers and students of fortification, combines practical and theoretical instruction. Its pictures are plain geometric diagrams of angles, arcs and bastion plans drawn in line with dotted construction guides and a measuring scale, offering designers a clear model for schematic layouts, compass-and-ruler constructions and minimal line diagrams.
