The inception of American regionalism is routinely identified by scholars in either Robert Beverley or William Byrd II, both native Virginians who wrote intensely local works (The History and Present State of Virginia, 1705 ; The History of the Dividing Line Betwixt Virginia and North Carolina, Run in the Year of Our Lord 1728) which are amongst the enduring literary products of colonial America. The regional base of both works is immediately apparent in their subjects and setting; but to stop here is to leave critical questions unanswered, questions which have in recent years begun to be addressed by ethnographers and historians such as David Bertelson, Michael Zuckerman and Kenneth Lockridge. In particular, Lockridge's study, meshing biography, history and social psychology, has proposed an illuminating “reconstruction of Byrd's personality” from his writings, an account which stresses Byrd's cultural predicament as a provincial Virginian who strove to be an English gentleman. My purpose in this paper is not to challenge such an interpretation, nor to propose an alternative historical viewpoint, but rather to add the perspective of literary criticism to our reading of Byrd's prose itself. I shall argue that the “ southernness” of Byrd's writing is a characteristic less of his subject matter — his Virginian material — or of his biographical limitations, than of his style, and that the History of the Dividing Line charts enduring preoccupations of Byrd's writing career which reached perfectly self-conscious apotheosis in this, his most carefully composed and corrected work.
