The Letters of Jonathan Oldstyle, Gent. is a compilation of eight humorous and observational letters written by American writer, Washington Irving, under the pseudonym, Jonathan Oldstyle. These eight letters and one additional were first published as a series of "Letters to the Editor" of the New York paper, The Morning Chronicle, between 1802 and 1803. In them Oldstyle skewered the local New York social scene on the topics of etiquette, marriage, fashion, and other particulars of human interaction.
