Question: In what area did the period of history, in which linear perspective was perfected, begin on the continent which contains the ridge known as the Gornergrat?

<P0-S0> the period saw several important technical innovations, like the principle of linear perspective found in the work of masaccio, and later described by brunelleschi. <P0-S1> greater realism was also achieved through the scientific study of anatomy, championed by artists like donatello. <P0-S2> this can be seen particularly well in his sculptures, inspired by the study of classical models. <P0-S3> as the centre of the movement shifted to rome, the period culminated in the high renaissance masters da vinci, michelangelo and raphael. <SEP> <P1-S0> The Renaissance (UK: / rɪˈneɪsəns /, US: / rɛnəˈsɑːns /) is a period in European history, covering the span between the 14th and 17th centuries. <P1-S1> It is an extension of the Middle Ages, and is bridged by the Age of Enlightenment to modern history. <P1-S2> It grew in fragments, with the very first traces found seemingly in Italy, coming to cover much of Europe, for some scholars marking the beginning of the modern age. <SEP> <P2-S0> It can be reached from Zermatt by the Gornergrat rack railway (GGB), the highest open-air railway in Europe. <P2-S1> The Gornergrat (; ) is a rocky ridge of the Pennine Alps, overlooking the Gorner Glacier south-east of Zermatt in Switzerland. <P2-S2> Between the Gornergrat railway station () and the summit is the Kulm Hotel () hosting the new Project "Stellarium Gornergrat" and until 2010 the "Kölner Observatorium für SubMillimeter Astronomie" KOSMA and before that (until 2005) the Gornergrat Infrared Telescope. <SEP> <P3-S0> Filippo Brunelleschi (Italian: (fiˈlippo brunelˈleski); 1377 -- April 15, 1446) was an Italian designer and a key figure in architecture, recognised to be the first modern engineer, planner and sole construction supervisor. <P3-S1> He is generally well known for developing a technique for linear perspective in art and for building the dome of the Florence Cathedral. <P3-S2> Heavily dependent on mirrors and geometry, to ``reinforce Christian spiritual reality '', his formulation of linear perspective governed pictorial depiction of space until the late 19th century. <P3-S3> It also had the most profound -- and quite unanticipated -- influence on the rise of modern science. <P3-S4> His accomplishments also include other architectural works, sculpture, mathematics, engineering, and ship design. <P3-S5> His principal surviving works are to be found in Florence, Italy. <P3-S6> He was one of the founding fathers of the Renaissance. <P3-S7> Unfortunately, his two original linear perspective panels have been lost. <SEP> <P4-S0> the thurian age is a specific epoch in the fictional timeline used by robert e. howard in his kull stories. <P4-S1> it predates the hyborian age of the conan the barbarian stories and is known to them as the "pre-cataclysmic age". <P4-S2> the main continent is called thuria, although smaller continents such as atlantis and an unnamed eastern continent exist, as do several island chains. <P4-S3> most of the world is unexplored wilderness inhabited by "scattered clans and tribes of primitive savages." <P4-S4> the boundary between the two ages is marked by the "great cataclysm," which might have taken place as early as ca. <P4-S5> 35,000 to 40,000 b.c, or as recently as 18,000 b.c. <P4-S6> depending on the sources considered. <P4-S7> when robert e. howard began to chronicle the adventures of conan the cimmerian, in the early 1930s, he prepared a fictional history of the hyborian age which he had created. <P4-S8> that "history" dealt not only with the period during and after conan's life, but also with events some eight thousand years earlier, during the thurian civilization which produced king kull, an exiled warrior from atlantis, in the days before his continent sank into the surging seas.
