As anyone who has delved into history of forgery can testify, sheer number of examples is positively breathtaking. Forgeries are ubiquitous. Yet it has also been noted, and in fact noted by many eighteenth-century commentators themselves, that Age of Reason produced an unusually large number of famous fakers: Thomas Chatterton, James Macpherson, George Psalmanazar, William Henry Ireland - to name just four, and just four in England. It is also striking degree to which period accounts of these forgeries routinely list other cases by way of comparison, many of which have been all but lost to us. A review of French edition of 's phony Description of Formosa, for example, published in 1705, compares him to false Princess of that had come to Paris a few years earlier. Some of her story has been preserved in memoirs of French Jesuit Louis Le Comte, who had spent considerable time in China and who had been called in to unmask her. He reports that she had been welcomed into most elite circles of Parisian aristocracy (and that she continued to play her role even after she had been exposed). We would certainly like to know more about her adventures.1A century later another East Asian impostor turned up in Bristol known as Princess Caraboo, who claimed to be from island of Javasu. Her story, like 's, is relatively well documented, and yet upon publication of full history of this female Psalmanazar in 1817, its author pauses to remind us of other cases such as fasting woman of Tetbury, Johanna Southcote, and the famous cheats and disguises of Bampfield More Carew.2 A 1764 review of Psalmanazar's memoirs lists Elizabeth Canning, Ashley and Jew, and Cock Lane Ghost.3 Subsequent writers such as William Hazlitt, Vita Sackville-West, and Ernest Hemingway all mention along with additional cases from their own day4The realm of literary forgery (including piracy) is even more densely populated, and not simply with famous examples like Chatterton, Macpherson, or William Lauder. Who remembers Richard Rolt, Alexander Innes, John Eccles, or William Douglas, M.D. - all of whom are listed in an aside on literary fraud in Boswell's Life of Johnson (1791)?5 A full list would be endless, and proliferation of fakes of every imaginable sort (counterfeits, frauds, impostures, hoaxes, art forgeries, pirated books) is matched only by our seemingly insatiable interest in finding out everything we can about them. Thus list of books about forgery is also dauntingly lengthy, both at macro and micro levels, both scholarly and popular, in all languages, fields, and periods. Do we really need another book on (eighteenth-century) forgery?It is into this minefield that Jack Lynch's new book, Deception and Detection in Eighteenth-Century Britain (Ashgate, 2008), bravely treads - and succeeds admirably. What is different about book is term detection, which is to say means by which eighteenth-century people actually went about trying to prove veracity (or lack thereof) of any particular claim. The real focus is not those who did faking but instead those who argued about it: How were these cases actually debated and discussed by eighteenth-century inquirers, and what do they tell us about eighteenth-century conceptions of world? (vii).The process of how a forgery could be proved or disproved was indeed undergoing major changes between time of (1704) and Ireland (1795), in arenas such as conception of personal identity and its consistency over time, of ownership of texts and copyright, of plagiarism and pirating, and of value and status of various kinds of legal evidence. Rather than organizing book according to individual examples and how each of them played itself out - a common technique that usually ends up just repeating stories themselves, entertaining as that might be - Lynch chooses to arrange material thematically. …
