An enduring puzzle of the Renaissance is why William Shakespeare ignores the astronomical revolutions of the sixteenth and early seventeenth centuries. He deals superficially with celestial phenomena and appears oblivious to the effects that new perceptions in cosmology were having on worldview. This book discusses the rise of evidence-based inquiry into natural phenomena and argues that Shakespeare's famous play, Hamlet, is an allegory describing the chief cosmological models that vied for acceptance at the turn of the seventeenth century.This book explains: WHY Hamlet is 30 and knows a hawk from a handsaw, WHAT Ophelia's name means, WHO Claudius, Rosencrantz and Guildenstern represent, WHEN telescopic astronomy began, WHERE 16th-century astronomy and theology intersect, HOW Shakespeare welcomes the New Philosophy and WHETHER he foresees its consequences. Read a review.

Prince Hamlet knows a hawk from a handsaw (Hamlet 2.2.347-8) because he recognizes two modes of astronomical data collection in the sixteenth century -- with telescopes and with the naked eye. The former has the advantage of hawk-like resolution, which far exceeds that of human vision. The latter is needed to explain the portrait of the world's leading naked-eye astronomer, a portion of which is depicted at the right.
"Hamlet's Love Letter and the New Philosophy" The Oxfordian 8 (2005) 93-109
Hamlet's love letter is another part of Hamlet that has both
literal and figurative meaning, first that
Polonius is justified in believing that Hamlet is madly in love with his
daughter, and second that Hamlet's letter is a parody of Aristotelianism, and
as such is further support for the cosmic allegorical interpretation of the
play. Through the agency of Hamlet's letter, Shakespeare continues his
disparagement of Aristotelianism that Thomas Digges engages in A Perfit
Description, as does Digges' favorite poet Palingenius in Zodiacus Vitae.
The love letter is ironical, as Hamlet dupes Polonius into announcing the
essential elements of the New Philosophy in the presence of the King who
epitomizes its very antithesis, viz. the bounded geocentricism of his namesake,
Claudius Ptolemy.

In 1610 in Sidereus Nuncius, Galileo reported that the planet Jupiter had four moons. Shakespeare and/or his collaborators celebrate this discovery in Cymbeline. Independent dating of Cymbeline suggests that the play appeared in late 1610.
