All of O'Nolan's other novels were published under the pseudonym Flann O'Brien; it is the only one for which he used the "Myles na gCopaleen" pseudonym that he was then using for his celebrated "Irish Times" column "Cruiskeen Lawn". (Subsequently O'Nolan altered the newspaper byline slightly to the more anglicised "Myles na Gopaleen".) Neither is a real Irish surname, however. Both derive from a character named Myles-na-Coppaleen in Dion Boucicault's 1860 play "The Colleen Bawn", which, in turn, comes from the Irish , "of the little horses". As if to confuse matters, the English translation of is published as the work of "Flann O'Brien".
