Plantae tinctoriae: The 1759 Dissertation on Dye Plants by Engelbert Jörlin

Abstract

In the late 1750s, the Swedish botanist Engelbert Jörlin (1733–1810), one of Carl Linnaeus’ students wrote his dissertation Plantae tinctoriae on more than one hundred dye plants. The article presents a systematic study on these dyeing materials and reflects the knowledge in the mid-18th century. His dissertation focused on domestic plants that could be suitable instead of expensive imported trade goods and was published during the Age of Utility (1719–1771). The Latin text of Jörlin’s dissertation was first converted into a digital version by the ‘Noscemus General Model’ from Transkribus and then translated into English. The current scientific names were obtained from various biological websites. The dyestuffs were assigned to four groups: native and applied in Sweden (A); imported trade products (B); native to Sweden with potential use for dyeing (C); non-native and used abroad (D). They were mainly applied for dyeing textiles, less frequently for pharmaceuticals, cosmetics (make-up), inks and artists’ pigments. In his dissertation, Jörlin refers to scriptures from antiquity, Latin botanical literature from the 16th and 17th centuries but especially to the publications of Carl Linnaeus.
