Both the copperplate and the print entitled Passementerie (a word for fancywork to create woven trim for clothing) depict the fabrication of a ribbon of multicolored silk called a nonpareille. To produce this ribbon, silk threads were fused together by passing them through the heated rollers of a mill. They were then sized with glue and wound onto a spool. Nonpareille were most frequently used to ornament women\u2019s dresses and hats.<\/p>\n<p>The copperplate was not executed for the <em>Encyclop\u00e9die <\/em>but for a project initiated at the end of the seventeenth century by the French Academy of Sciences. Called the <em>Description des Arts et M\u00e9tiers<\/em>, its aim was to document the mechanical arts and trades. Although the first volumes of the Academy\u2019s publication were not issued until 1761, plates had been produced for it from the project\u2019s inception. Diderot was familiar with them, as his adoption of their characteristic division of a plate to show a workshop vignette and details of tools shows. Indeed, the plates were so close in design that in 1759 Diderot was charged with plagiarism. He was later exonerated.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The plates in the Encyclop\u00e9die were created using copperplates in which the image was engraved in reverse.
