The History of the Caliph Vathek - William Beckford

This is one of the earliest Gothic novels. The Caliph Vathek is one of the wealthiest and most powerful men who ever lived. But this is not enough for him. He seeks also forbidden knowledge, and doesn't care who he has to hurt to get it. Aided by his depraved mother Carathis, Vathek proceeds to damn himself, and those around him.
