Though he was Belgian, Félicien Rops was instrumental in the development of this early stage of the Decadent movement. A friend of Baudelaire, he was a frequent illustrator of Baudelaire's writing, at the request of the author himself. Rops delighted in breaking artistic convention and shocking the public with gruesome, fantastical horror. He explicitly was interested in the Satanic, and he frequently sought to portray the double-threat of Satan and Woman. At times, his only goal was the portrayal of a woman he'd observed debasing herself in the pursuit of her own pleasure. It has been suggested that, no matter how horrific and perverse his images could be, Rops' invocation of supernatural elements was sufficient to keep Baudelaire situated in a spiritually aware universe that maintained a cynical kind of hope, even if the poetry "requires a strong stomach." Their work was the worship of beauty disguised as the worship of evil. For both of them, mortality and all manner of corruptions were always on their mind. The ability of Rops to see and portray the same world as they did made him a popular illustrator for other decadent authors.
