WHAT DID SHAKESPEARE KNOW ABOUT COPERNICANISM?
Just why did Shakespeare, for example, choose the names of Rosenskrantz and
Guildenstern for Hamlet’s petard-hoisted companions, two historical
> relatives of Tycho Brahe (the foremost astronomer during Shakespeare’s
floruit)? What was Shakespeare’s relationship to the spread of Copernican
cosmology in late Elizabethan England? Was he impacted by such
Copernican-related currents of cosmological thought as the atomism of
Thomas Harriot and Nicholas Hill, the Neoplatonism of Kepler, and the
heliocentrism of John Dee and William Gilbert? Does the language of
Shakespeare’s plays support the idea that Shakespeare had an in-depth
knowledge of technical astronomy on the order of Chaucer (who wrote an
instruction manual for an astronomical instrument, the astrolabe), or that
Shakespeare understood the implications of Copernican astronomy?
