Theatre des instrumens mathematiques & mechaniques
A 1578 Lyon edition of Jacques Besson's mechanical treatise, with plates by Jacques Androuet du Cerceau and René Boyvin, intended for engineers, craftsmen and mathematicians. The engraved plates show machines in working detail: a lifting device with a large wheel, a screw-driven drive with a geared wheel and horse-powered mechanism, and a stepped cone-and-bar frame with geometric base profiles. A designer might take the crisp hatched line work and the clear, diagrammatic layout of mechanical parts.
