George III's queen disliked it, and Napoleon took it with him on his Egyptian campaign. It was the first novel read by the hero-monster of Mary Shelley's "Frankenstein." Though its contemporary popularity was immense, Longfellow later said, "In England and America the book is sneered at; I think it is not understood."
