A careful student of the Romantic poets will soon or late encounter the name of Thomas Taylor, whose chief claim to importance is that he was an extraordinarily diligent scholar and the first translator into English of all Plato's works. An inquirer will find brief and not always accurate accounts of this man in several encyclopedias; he will discover that certain nineteenth-century antiquarians wrote a number of sketches of Taylor in which fact is liberally sprinkled with fiction; and finally, he will come upon half a dozen more recent articles of a scholarly nature, including an almost complete bibliography of Taylor's books, three papers suggesting rather doubtful parallels between some passages of these and certain poems of Blake and Wordsworth, one which reprints from manuscript sources a few of Taylor's own poems, and another which endeavors unsuccessfully to demonstrate an acquaintance between Taylor and Shelley. Taylor's various translations and original works have also been cited occasionally in studies such as Professor Lowes's The Road to Xanadu. But with all this array of scholarship, imposing when it is called forth by a man so obscure as Thomas Taylor, there is still no comprehensive or accurate account of the man himself and his work. He is important, however, as the most energetic exponent of Platonism in England between the Cambridge Platonists and Benjamin Jowett, this at a time when Platonism once more became significant in literature after the eighteenth-century dismissal of Plato. Yet before we have a study of Taylor's Platonism in its relation to that of the Romantic poets, we should have a reasonably trustworthy biography of the man. For although it will not be found that Thomas Taylor was a person of hitherto unrecognized and startling importance for the student of literature, it is certain that he was known to such people as James Boswell, Thomas Holcroft, Thomas Love Peacock, Mary Wollstonecraft, probably William Blake, and quite possibly Shelley; that his books were read by Shelley, Wordsworth, Coleridge, Southey, and Emerson in America; and that he was a conspicuous figure in the intellectual world of England during the late eighteenth and early nineteenth centuries. Since the available accounts of him are incomplete and contradictory, he deserves the services of a biographer who will simply collect and set forth the facts.
