During the XIXth Century, Belgium was an asylum for French authors. A French author, known for his poetry collection "Les fleurs du mal" ("The Flowers of Evil"), has declared "I consider it useless and tedious to represent what exists, because nothing that exists satisfies me." According to a TV quiz show, he also said "Belgian cuisine and Belgian women are the worst on Earth". However, I found no evidence for this last quote. Who was this French author?
