Pynchon's synopsis states that the novel's action takes place "between the 1893 Chicago World's Fair and the years just after World War I". "With a worldwide disaster looming just a few years ahead, it is a time of unrestrained corporate greed, false religiosity, moronic fecklessness, and evil intent in high places. No reference to the present day is intended or should be inferred." Pynchon promises "cameo appearances by Nikola Tesla, Bela Lugosi and Groucho Marx", as well as "stupid songs" and "strange sexual practices".
