On 27 September 1871 there appeared in an inconspicuous corner of the New York Tribune a piece by Mark Twain entitled “The Revised Catechism.” Obviously drawing on his Sunday School memories of the Westminster Catechism for the form of the contribution, Clemens makes use also of the Bible (a work thoroughly learned in his boyhood and never forgotten) for striking satirical effect. “The Revised Catechism” is a scathing denunciation of Boss Tweed and his associates—as accomplished a group of rascals as ever pillaged a public treasury—and at the same time an indictment of the age that permitted such men to thrive. The story of the Tammany Ring is too well known to need retelling here; but to make clear the reasons that led Mark Twain to the writing of his satire and to demonstrate the ironical character of his references, so apposite to the day and hour, it is necessary to consider briefly the part played in the exposure of the Ring by its two principal antagonists—one, the cartoonist, Thomas Nast, and the other, the New York Times.
