En tibi lector Robertvm Valtvrivm ... de re militari : libris XII multo emaculatius, ac picturis... expressum...
A 1532 Latin edition of Roberto Valturio's treatise on military affairs, printed in Paris by Christian Wechel for scholars and military men. Its woodcut plates show siege engines, ladders, a battering ram and mobile shelters drawn in clean outline with simple ground lines, giving designers clear, legible mechanical diagrams to reference for structure and form.
