In Shakespeare and the Dawn of Modern Science, renowned astronomy expert Peter Usher expands upon his allegorical interpretation of Hamlet and analyzes four more plays, Love's Labour's Lost, Cymbeline, The Merchant of Venice, and The Winter's Tale. With painstaking thoroughness, he dissects the plays and reveals that, contrary to current belief, Shakespeare was well aware of the scientific revolutions of his time. Moreover, Shakespeare imbeds in the allegorical subtext information on the appearances of the Sun, Moon, planets, and stars that he could not have known without telescopic aid, yet these plays appeared coeval with or prior to the commonly accepted date of 1610 for the invention and first use of the astronomical telescope. Dr. Usher argues that an early telescope, the so-called perspective glass, was the likely means for the acquisition of these data. This device was invented by the mathematician Leonard Digges, whose grandson of the same name contributed poems to the First and Second Folio editions of Shakespeare's plays. Shakespeare and the Dawn of Modern Science is an important addition to literature, history, and science collections as well as to personal libraries.

In a novel reading of Shakespeare's plays, this book addresses an observation first made many decades ago, that Shakespeare appears to neglect the intellectual upheavals that astronomy brought about in his lifetime. The author examines temporal, situational, and verbal anomalies in Hamlet and other plays using hermeneutic-dialectic methodology, and finds a consistent pattern of interpretation that is compatible with the history of astronomy and with the development of modern cosmology. He also demonstrates how Shakespeare takes into account beliefs about the nature of the heavens from the time of Pythagoras up to and including discoveries and theories in the first decade of the seventeenth century. The book makes the case that, as in many other fields, Shakespeare's celestial knowledge is far beyond what was commonly known at the time. Students and teachers interested in Shakespeare's alleged indifference towards, or ignorance of, the celestial sciences will find this book illuminating, as will historians of science and scholars whose work focuses on epistemology and its relationship to the canon, and on how Shakespeare acquired the data that his plays deliver.

In the mid-sixteenth century, Copernicus asserted that the Earth was not the center of the universe as was generally believed, but that the sun lay there instead. The relegation of the Earth to the rank of an orbiting planet meant that humankind lost its privileged position as well, thus prompting re-evaluation of all facets of human existence. This transformation in worldview gathered momentum throughout Shakespeare's writing career, yet his canon appears to lack reference to it. Peter D. Usher has studied Hamlet and other Shakespearean plays and has uncovered a consistent pattern of reference to phenomena that prove the correctness of the new worldview, including reference to the infinite universe of stars. These data could not have been known without telescopic aid, which indicates that systematic telescopic study of celestial objects began before the generally accepted date of 1610. In Shakespeare and Saturn, Usher summarizes earlier results and shows that in All's Well That Ends Well, Shakespeare takes account of the last supernova eruption of 1604 known to have occurred in the Milky Way galaxy. He shows further that in Much Ado About Nothing and The Comedy of Errors Shakespeare makes observations concerning Saturn's spectacular ring system that are remarkably accurate.
