Overview
Against the Day is an epic historical novel by Thomas Pynchon, published in 2006. The narrative takes place between the 1893 Chicago World's Fair and the time immediately following World War I and features more than a hundred characters spread across the United States, Europe, Mexico, Central Asia, Africa and "one or two places not strictly speaking on the map at all," according to the book jacket blurb written by Pynchon. Like its predecessors, Against the Day is an example of historiographic metafiction or metahistorical romance. At 1,085 pages, it is the longest of Pynchon's novels to date.
Title
Besides appearing within the book itself, the novel's title apparently refers to a verse in the Bible (2 Peter 3:7) reading "the heavens and the earth ... [are] reserved unto fire against the day of judgment and perdition of ungodly men."
William Faulkner, whose diction frequently echoes the King James Bible, liked the phrase, and many reviewers have traced it to a speech of Faulkner's against racism. Perhaps as relevant is a passage in Absalom, Absalom! in which Sutpen, a Faustus character of the sort that Pynchon deploys everywhere, seeks "a wife who not only would consolidate the hiding but could would and did breed him two children to fend and shield both in themselves and in their progeny the brittle bones and tired flesh of an old man against the day when the Creditor would run him to earth for the last time and he couldn't get away." The Creditor there is Mephistopheles, to whom Faustus/Sutpen would owe his soul. (The passage in Gravity's Rainbow about the "black indomitable oven" with which the witch-like Blicero, another Faustus character, is left once the Hansel-and-Gretel-like children have departed, alludes to another passage in Absalom, Absalom!.)
Nonliterary sources for the title may also exist: Contre-jour (literally "against (the) day"), a term in photography referring to backlighting. There are also two uses of the phrase "against the day" in Pynchon's Mason & Dixon, and four appearances in William Gaddis's J R.
