Engraving by Benard after Lucotte, of craftsmen heating and hammering horn. Below are illustrations of how the horn was cut. Its many uses included spectacle frames, gunpowder containers, drinking vesels and hunting horns. From volume 8 of 'Encyclopedie, ou Dictionnaire Raisonne des Sciences, des Arts et des Metiers', edited by Denis Diderot (1713-1784) and Jean d'Alembert (1717-1783) and published in 14 volumes between 1751 and 1765. The 'Grand Encyclopedie' (Encyclopedia or Dictionary of the Sciences, Arts and Profesions) was more than a summary of all contemporary knowledge, it served as a manifesto for a new way of looking at the world by describing many of the proceses which transformed the world during the Industrial Revolution.
