The monster's namelessness became part of the stage tradition as Mary Shelley's story was adapted into serious and comic plays in London and Paris during the decades after the novel's first appearance. Mary Shelley herself attended a performance of Presumption, the first successful stage adaptation of her novel. "The play bill amused me extremely, for in the list of dramatic personae came _________, by Mr T. Cooke,” she wrote to her friend Leigh Hunt. "This nameless mode of naming the unnameable is rather good."
