The fictional character Torchia was described as follows. He was born in 1620. He was apprenticed in Leyden under the Elzevir family. After returning to Venice he published small works on philosophical and esoteric themes. In 1666, Torchia published De Umbrarum Regni Novem Portis (The Nine Doors to the Kingdom of Shadows), which was in turn based on the Delomelanicon, or Invocation of Darkness , a work supposedly written by Lucifer and that would allow the reader to summon devils. The Inquisition condemned Torchia for magic and witchcraft and burned him at the stake in 1667.
