Impressions of Theophrastus Such is a work of fiction by George Eliot (Marian Evans), first published in 1879. It was Eliot's last published writing and her most experimental, taking the form of a series of literary essays by an imaginary minor scholar whose eccentric character is revealed through his work. In a series of eighteen sometimes satirical character studies, Theophrastus Such focuses on various types of people he has observed in society. Usually, Theophrastus Such acts as a first-person narrator, but at several points, the voice of Theophrastus Such is lost or becomes confused with Eliot's omniscient perspective. Some readers have identified biographical similarities between Eliot herself and the upbringing and temperament Theophrastus Such claims as his own. In her letters, George Eliot describes herself using many of the same terms.
