Tristan is a 1903 novella by German writer Thomas Mann. It contains many references to the myth of Tristan and Iseult. The novella alludes in particular to the version presented in Richard Wagner's opera of the same name. As such, it can be seen as an ironic paraphrase, juxtaposing the romantic heroism of Wagner's characters with their essentially flawed counterparts in the novella. It also heavily deals with psychology and a major part of the novel is set in a sanatorium and details the lives of two people who are patients at the sanatorium.
