Machines et inventions approuvées par l'Académie Royale des Sciences depuis son établissement jusqu'à présent
Machines et inventions approuvées par l'Académie Royale des Sciences is a 1734 Paris compendium of machines and inventions approved by the Royal Academy of Sciences, edited by the Académie des Sciences for engineers and mechanics. The four pictures show the same symmetrical ornamental headpiece, a central foliage cluster flanked by scrolls, urns and leafy sprays, printed in dark ink on a pale page. A designer could take its balanced bilateral scrollwork and vine-and-scroll motifs as a model for ornamental borders or title devices.
