Jacques Casanova (1725-1798) was a Venetian author and adventurer. World-famous as a seducer of women, Casanova also socialized with popes, royalty, and such great minds as Voltaire and Mozart. Educated in Padua, he lived in many other places, including Constantinople, Prague, Switzerland, France, Germany, England, Russia, Austria, Belgium, and Spain. Casanova finished his days in Bohemia as the librarian to Count Joseph Karl von Waldstein.
Arthur Machen (1863-1947), born Arthur Llewelyn Jones, was a Welsh author of Gothic-revival fantasy and horror stories which mixed fright with sex and decadence, and influenced other horror writers like H. P. Lovecraft. His “The Great God Pan” (1890) was deemed “Maybe the best [horror story] in the English language” by Stephen King.
