1756 Grammaire des Sciences Philosophiques — Vellum-Bound Scientific Encyclopaedia with Newtonian & Copernican Fold-Out Plates

A remarkable mid-18th-century scientific encyclopaedia, bound in contemporary full vellum and complete with an exceptional collection of engraved fold-out plates documenting the scientific knowledge of the period of the Enlightenment.

Grammaire des Sciences Philosophiques (La Haye, 1756) provides a structured and comprehensive introduction of modern philosophy and the physical sciences, adapted from the influential works of English instrument-maker and scientific popularizer Benjamin Martin. This French edition became an essential gateway to Newtonian thought on the Continent, offering readers a clear, experiment-based introduction to physics, astronomy, meteorology, optics, zoology, botany, microscopy, hydrology, geology, and more.

Inside, a range of 25 plus richly engraved fold-out plates depicting:
*Newtonian physics & experimental machines (levers, pulleys, pneumatics, optical instruments)
*The Copernican solar system, planetary motions, cometary paths, and eclipses
*Astronomical tables, lunar maps, and stellar diagrams
*Meteorological studies including rainbows, halos, winds, tides, and atmospheric patterns
*Microscopic botanical engravings—roots, stems, cellular structures
*Zoological plates featuring fishes, mollusks, insects, caterpillars, and butterflies
*A world map of winds and monsoons
*Detailed density tables for solids and liquids

The vellum binding bears a blind-stamped central ornament, yapped edges, and hand-lettered spine, displaying typical toning and aging for a mid-18th-century vellum binding. An extraordinary piece for collectors of antique science, Enlightenment thought, vellum bindings, astronomy, or natural history.
