There is a Kickstarter campaign to fund the publication of an English translation of The Devil in the 19th Century – A Witness Account.
The posted description says:
“Secret societies, dark rituals, devil-worshipping Freemasons, the Antipope (an American, to boot!), a mysterious young woman rumoured to have been fathered by Lucifer himself… and the Catholic doctor ready to expose them all to the world.
“Forgotten today in all but niche academic circles, the 1890s Taxil Hoax fooled the Vatican, enraged the Freemasons and captivated French readers.
“The witness account that started it all – purportedly written by “Doctor Bataille” – was published as a series of pamphlets from 1892 to 1897 under the title Le Diable au XIXe Siècle.
“Part travel journal and part investigative report, filled with carefully transcribed rituals and a rich cast of shady characters, it is a thrilling, lurid and sensationalist read.
“There has never been an English translation… until now.”
