Amsterdam, for the author by Joannes Punt, [1759]. 4to. Contemporary marbled calf, gold-tooled spine with title-label. With 3 large folding engraved plates (ca. 49 x 26 cm) by Joannes Punt after drawings by the author, 2 engravings in text by D. van Duffel and some woodcut head- and tailpieces. XVI, 122 pp.

First and only edition of a rare work by the Dutch engineer Cornelis Redelykheid (1728-1787) on how to improve the masonry and the composition of strongholds against hostile artillery and mines as well as the protection of their vaults to prevent the striking of heavy bombs. The very large engraved plates with technical drawings depict a plan of a fortress and several cross-sections of different parts such as vaults.
Cornelis Redelykheid worked as a young man in his father's shop, who was a mason. Later he became a capable hydraulic, mechanical and fortification engineer. Redelykheid wrote many works on engineering and he was the inventor of the lift-lock with sliding locks in 1773 for which he received 1000 gold ducates of the Dutch government.
With a library stamp on the title-page, some faint foxing in the margins of the plates, not affecting the illustrations. Very good copy, with wide margins on thick paper.
