A World View of Robert Recorde: A Brief Study of Tudor Cosmology
In 1556, Robert Recorde (1510?-1558) provided the English reading public with the first significant reference to the heliocentric theories of Nicholas Copernicus. In a brief passage in his elementary text on astronomy,The Castle of Knowledge, Recorde introduced the fact that Copernicushathe renewed the opinion of Aristarchus Samius, andaffirmeth that the earthe not only moueth circularlyeabout his owne centre, but also may be, yea and is,continually out of the precise cētre of the world 38hundredth thousand miles:This statement, preceded by a review of other ancient astronomers who held similar views, and followed by a promise to the reader that the subject would be examined later in greater detail, constituted the complete reference to Copernicus and his theories. It was neither an endorsement nor a repudiation of the revolutionary theories advanced by Copernicus. Given his reputation as a competent and thorough scholar, one may legitimately ask, first, why did Recorde limit himself to such a short statement? and, second, how can his attitude toward the heliocentric theories be established with greater certainty? Because Recorde elected not to commit himself further inThe Castle of Knowledge, any discussion of his attitude toward the new theories must be based on indirect evidence. The point to be demonstrated is that Recorde was influenced by a particular philosophy that enabled him to view favorably the theories advanced in Copernicus's great work,De Revolutionibus Orbium Celestium. The first part of this study examines some probable causes for Recorde's reluctance to expand upon his reference to Copernicus, while the remainder examines his philosophical views.
