This collection includes an Engraving from Denis Diderot's Encyclopedia ("Encyclopedie"), entitled "Aiguiller-Bonnetier" ("Needle and Cap Makers"). Denis Diderot was a prominent philosopher during the Enlightenment. His most famous work was the Encyclopedia ("Encyclopedie"), a massive, multi-volume compilation of world knowledge richly illustrated with engravings. The Encyclopedia was groundbreaking in its inclusion of the "mechanical arts," or crafts and trades, as exemplified in this engraving of the Needle and Cap Makers. This engraving depicts a workshop with the textiles tools and equipment shown individually underneath.
