In the novel itself, he is compared with Prometheus from the Greek myths. English literature scholar Mimi Reisel Gladstein sees similarities to the figures of Arthur and Galahad from the Arthurian legends. Parallels have also been drawn to Captain Nemo, the anti-hero of Jules Verne's "20,000 Leagues Under the Sea", who has likewise turned his back on "civilization" in self-imposed exile with a number of chosen allies, refusing to partake in a society he views as irreconcilably evil and oppressive. Galt is not necessarily intended to be a rounded or realistic character; he has been called "more a symbol than a person" and "two-dimensional". Mimi Reisel Gladstein describes Galt as "more icon than character". Rand's own notes indicate that she expected the character to have "[n]o progression" and "no inner conflict" because he was "integrated (indivisible) and perfect". The book's opening line, "Who is John Galt?", becomes an expression of helplessness and despair at the current state of the novel's fictionalized world. The book's protagonist, Dagny Taggart, hears a number of legends of Galt, before finding him. In one legend Galt seeks the lost island of Atlantis, in another he discovers the Fountain of Youth. After eventually joining Galt's cause, Taggart learns that all of the stories have an element of truth to them. She names the Colorado spur of her railroad line the "John Galt Line" which surprises many people. When asked "Who is John Galt?", she replies "We are!" "The book's hero, John Galt, also continues to live on", wrote journalist Harriet Rubin in a September 2007 article about the influence of "Atlas Shrugged". Rubin mentions John Galt Solutions (a software company) and the John Galt Corporation (a demolition company) as examples of companies named after the character. The use of Galt as a symbol in the context of political or social protest has taken root in some places. The phrase "going John Galt" or simply "going Galt" has been used by psychologist Helen Smith and others to describe productive members of society cutting back on work in response to the projected increase in U.S. marginal tax rates, increased limits on tax deductions, and the use of tax revenues for causes they regard as immoral. "Who is John Galt?" signs were seen at Tea Party protests held in the United States and at banking protests in London in April 2009.
