In all, our volume contains three parts of the famous "Theatrum machinarum" of Leupold, the first systematic treatment of mechanical engineering and one of the most impressive large format technological publications of the 18th century. Our part 1 and 3 are part 7 and 10 of the first ed. (1724-1739). Our part 2 is an edition of part 8 (1st ed. 1727). Each part is complete in itself, totalling 141 impressive, finely engraved full-page plates.
