Post Lot Text
First edition of Guericke's own report on his famous Magdeburg experiment with air-pressure. Gaspar Schott had already described it 15 years earlier (see lot 157). The full-sheet engraved plate showing two teams of horses in a vain attempt to pull apart two copper hemispheres from which the air has been pumped, has become one of the most reproduced illustrations in the history of science, but other engravings in the edition also confirm the second half of the 17th century as the Dutch golden age in book illustration. Guericke's discovery of the air-pump and his description of it are of the greatest importance, but his many discoveries in electricity and electrical phenomena are also explained and signify important advances on Gilbert (see the previous lot). Fine copy, in contemporary Dutch vellum.
