as a mysticist recalcitrant in accepting the Copernican revolution, and valuing mostly his observations that allowed Kepler to formulate his laws of planetary movement. Especially in Danish scholarship, Tycho was depicted as a mediocre scholar and a traitor to the nation—perhaps because of the important role in Danish historiography of Christian IV as a warrior king. In the second half of the 20th century, scholars began reevaluating his significance, and studies by Kristian Peder Moesgaard, Owen Gingerich, Robert Westman, Victor E. Thoren, and John R. Christianson focused on his contributions to science, and demonstrated that while he admired Copernicus he was simply unable to reconcile his basic theory of physics with the Copernican view. Christianson's work showed the influence of Tycho's Uraniborg as a training center for scientists who after studying with Tycho went on to make contributions in various scientific fields. Scientific legacy Although Tycho's planetary model was soon discredited, his astronomical observations were an essential contribution to the scientific revolution. The traditional view of Tycho is that he was primarily an empiricist who set new standards for precise and objective measurements. This appraisal originated in Gassendi's 1654 biography, Tychonis Brahe, equitis Dani, astronomorum coryphaei, vita. It was furthered by Dreyer's biography in 1890, which was long the most influential work on Tycho. According to historian of science Helge Kragh, this assessment grew out of Gassendi's opposition to Aristotelianism and Cartesianism, and fails to account for the diversity of Tycho's activities. The Tycho Brahe Prize, inaugurated in 2008, is awarded annually by the European Astronomical Society in recognition of the pioneering development or exploitation of European astronomical instrumentation, or major discoveries based largely on such instruments. Cultural legacy Tycho's discovery of the new star was the inspiration for Edgar Allan Poe's poem "Al Aaraaf". In 1998, Sky & Telescope magazine published an article by Donald Olson, Marilynn S. Olson and Russell L. Doescher arguing, in part, that Tycho's supernova was also the same "star that's westward from the pole" in Shakespeare's Hamlet. Tycho is directly referenced in Sarah Williams' poem The Old Astronomer: "Reach me down my Tycho Brahé,—I would know him when we meet". Though, the poem's oft quoted line comes later: "Though my soul may set in darkness, it will rise in perfect light; / I have loved the stars too truly to be fearful of the night." Alfred Noyes also wrote a long biographical poem in
