The Harmony of the World. Johannes Kepler. Johanne Kepler's "Harmonice mundi" was planned in as a sequel to the "Mysterium cosmographicum. The authors have presented and interpreted Kepler's Latin text to readers of English, by putting it into "the kind of clear but earnest language which we suppose Kepler would have used if he had been writing today. Preamble and Explanation of the Order.

The title translates as the Harmony of the Worlds. The musical theory provided astronomers and philosophers with a rational explanation for the arrangement of the heavenly bodies. This particular copy is sumptuously bound in parchment with the coat of arms of King James surrounded by fleur de lys and thistles, all tooled in gold Fig.
The binding suggests that the book was part of the Royal Collection at one time, and it is possible that this is the copy that Kepler presented to the King. As the Royal Library is still very much intact, the next question is how the volume ended up at Univ rather than Windsor. On the inside of the cover there is an engraved bookplate Fig. The bookplate belongs to Arthur Charlett who was Master of Univ from In , while serving as Master, Charlett was appointed a royal chaplain. The most creditable scenario is that the volume was presented to Charlett as a gift from the Royal Household.
If this is the copy which Kepler presented to the King it is conceivable that the corrections are in the hand of the author. Who else would have presumed to correct his work? Further selected Univ Treasures are detailed below or explore the whole collection on our News and Features Treasures pages.
Mathematical Treasure: Kepler’s Harmony of the Worlds
In the work, written entirely in Latin, Kepler discusses harmony and congruence in geometrical forms and physical phenomena. The final section of the work relates his discovery of the so-called " third law of planetary motion ". Kepler began working on Harmonices Mundi sometime near , which was the year Kepler sent a letter to Michael Maestlin detailing the mathematical data and proofs that he intended to use for his upcoming text, which he originally planned to name De harmonia mundi. Kepler was aware that the content of Harmonices Mundi closely resembled that of the subject matter for Ptolemy 's Harmonica, but was not concerned.
His search for order in the universe led Johann Kepler to the five Platonic Solids and their ordering as a divine plan for the movement of the planets. He articulated this theory in his Mysterium Cosmographicum , but felt that his theories warranted further explanation and refinement. I am writing a book for my contemporaries or — it does not matter — for Posterity. It may be that my book will wait for a hundred years for a Reader. Has not God waited for years for an observer?
Number to Sound pp Cite as. In surveying the development of the history of western music, two different currents can be singled out in the way it is understood; they take alternate predominance but also pervade and stimulate each other. On the one hand, there is a mainly mathematical-speculative understanding that does not place its main emphasis on the sound of tones but on the rational activity of speculation. From this point of view, the quality of the sound of music stretches beyond itself and serves to realize a supramusical order and regularity. It finds fulfillment in the imitation of this intelligible order. On the other hand, there is a conception of music which, by contrast, places its emphasis on the quality of sound and aims to enquire into real music, with its laws and effects on man.
