These illustrations originate from a compendium about magic and demonology from ca. 1775: Compendium rarissimum totius Artis Magicae sistematisatae per celeberrimos Artis hujus Magistros. Anno 1057. Noli me tangere.
The book, which is owned by the Wellcome Library in London, was written in German and Latin and features 31 water-colour drawings of demons, and several pages of magical and cabbalistic signs and sigils. The Wellcome Library digitized the book illustrations and made some images available for download under CC BY 4.0 on their images database (search for magic compendium).
