Question: In which area of the continent of Gornergrat did the period during which the mosaic fell out of fashion begin?

full_context: Document 1: Gornergrat: The Gornergrat (; ) is a rocky ridge of the Pennine Alps, overlooking the Gorner Glacier south-east of Zermatt in Switzerland. It can be reached from Zermatt by the Gornergrat rack railway (GGB), the highest open-air railway in Europe. 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.
Document 2: Mosaic: Greek figural mosaics could have been copied or adapted paintings, a far more prestigious artform, and the style was enthusiastically adopted by the Romans so that large floor mosaics enriched the floors of Hellenistic villas and Roman dwellings from Britain to Dura-Europos. Most recorded names of Roman mosaic workers are Greek, suggesting they dominated high quality work across the empire; no doubt most ordinary craftsmen were slaves. Splendid mosaic floors are found in Roman villas across North Africa, in places such as Carthage, and can still be seen in the extensive collection in Bardo Museum in Tunis, Tunisia.
Document 3: Mosaic: Bronze age pebble mosaics have been found at Tiryns; mosaics of the 4th century BC are found in the Macedonian palace-city of Aegae, and the 4th-century BC mosaic of The Beauty of Durrës discovered in Durrës, Albania in 1916, is an early figural example; the Greek figural style was mostly formed in the 3rd century BC. Mythological subjects, or scenes of hunting or other pursuits of the wealthy, were popular as the centrepieces of a larger geometric design, with strongly emphasized borders. Pliny the Elder mentions the artist Sosus of Pergamon by name, describing his mosaics of the food left on a floor after a feast and of a group of doves drinking from a bowl. Both of these themes were widely copied.
Document 4: Modern history: The term "modern" was coined in the 16th century to indicate present or recent times (ultimately derived from the Latin adverb modo, meaning "just now). The European Renaissance (about 1420–1630), which marked the transition between the Late Middle Ages and Early Modern times, started in Italy and was spurred in part by the rediscovery of classical art and literature, as well as the new perspectives gained from the Age of Discovery and the invention of the telescope and microscope, expanding the borders of thought and knowledge.
Document 5: Säntis: At 2,501.9 metres above sea level, Säntis is the highest mountain in the Alpstein massif of northeastern Switzerland. It is also the culminating point of the whole Appenzell Alps, between Lake Walen and Lake Constance. Shared by three cantons, the mountain is a highly visible landmark thanks to its exposed northerly position within the Alpstein massif. As a consequence, houses called "Säntisblick" (English: "Säntis view") can be found in regions as far away as the Black Forest in Germany. Säntis is among the most prominent summits in the Alps and the most prominent summit in Europe with an observation deck on the top. The panorama from the summit is spectacular. Six countries can be seen if the weather allows: Switzerland, Germany, Austria, Liechtenstein, France, and Italy.
Document 6: Middle Ages: In the history of Europe, the Middle Ages or Medieval Period lasted from the 5th to the 15th century. It began with the fall of the Western Roman Empire and merged into the Renaissance and the Age of Discovery. The Middle Ages is the middle period of the three traditional divisions of Western history: classical antiquity, the medieval period, and the modern period. The medieval period is itself subdivided into the Early, High, and Late Middle Ages.
Document 7: Oberrothorn: The Oberrothorn (3,414 m) is a mountain of the Swiss Pennine Alps, overlooking Zermatt in the canton of Valais. Its summit can be easily reached via a trail on its southern flank, from the Unterrothorn cable car station or from Sunnegga.
Document 8: Middle Ages: In the history of Europe, the Middle Ages (or Medieval Period) lasted from the 5th to the 15th century. It began with the fall of the Western Roman Empire and merged into the Renaissance and the Age of Discovery. The Middle Ages is the middle period of the three traditional divisions of Western history: classical antiquity, the medieval period, and the modern period. The medieval period is itself subdivided into the Early, High, and Late Middle Ages.
Document 9: Mosaic: In parts of Italy, which were under eastern artistic influences, like Sicily and Venice, mosaic making never went out of fashion in the Middle Ages. The whole interior of the St Mark's Basilica in Venice is clad with elaborate, golden mosaics. The oldest scenes were executed by Greek masters in the late 11th century but the majority of the mosaics are works of local artists from the 12th–13th centuries. The decoration of the church was finished only in the 16th century. One hundred and ten scenes of mosaics in the atrium of St Mark's were based directly on the miniatures of the Cotton Genesis, a Byzantine manuscript that was brought to Venice after the sack of Constantinople (1204). The mosaics were executed in the 1220s.
Document 10: Late Middle Ages: Modern historiography on the period has reached a consensus between the two extremes of innovation and crisis. It is now (generally) acknowledged that conditions were vastly different north and south of the Alps, and "Late Middle Ages" is often avoided entirely within Italian historiography. The term "Renaissance" is still considered useful for describing certain intellectual, cultural, or artistic developments, but not as the defining feature of an entire European historical epoch. The period from the early 14th century up until – and sometimes including – the 16th century, is rather seen as characterised by other trends: demographic and economic decline followed by recovery, the end of western religious unity and the subsequent emergence of the nation state, and the expansion of European influence onto the rest of the world.
Document 11: Matterhorn: The Matterhorn (German: Matterhorn, (ˈmatərˌhɔrn); Italian: Cervino, (ˈtʃerˈviːno); French: Le Cervin, (mɔ̃ sɛʁvɛ̃)) is a mountain of the Alps, straddling the main watershed and border between Switzerland and Italy. It is a large, near - symmetrical pyramidal peak in the extended Monte Rosa area of the Pennine Alps, whose summit is 4,478 metres (14,692 ft) high, making it one of the highest summits in the Alps and Europe. The four steep faces, rising above the surrounding glaciers, face the four compass points and are split by the Hörnli, Furggen, Leone, and Zmutt ridges. The mountain overlooks the Swiss town of Zermatt, in the canton of Valais, to the north - east and the Italian town of Breuil - Cervinia in the Aosta Valley to the south. Just east of the Matterhorn is Theodul Pass, the main passage between the two valleys on its north and south sides, and a trade route since the Roman Era.
Document 12: Mosaic: Mosaic has a long history, starting in Mesopotamia in the 3rd millennium BC. Pebble mosaics were made in Tiryns in Mycenean Greece; mosaics with patterns and pictures became widespread in classical times, both in Ancient Greece and Ancient Rome. Early Christian basilicas from the 4th century onwards were decorated with wall and ceiling mosaics. Mosaic art flourished in the Byzantine Empire from the 6th to the 15th centuries; that tradition was adopted by the Norman kingdom in Sicily in the 12th century, by eastern-influenced Venice, and among the Rus in Ukraine. Mosaic fell out of fashion in the Renaissance, though artists like Raphael continued to practise the old technique. Roman and Byzantine influence led Jews to decorate 5th and 6th century synagogues in the Middle East with floor mosaics.
Document 13: Mosaic: The heyday of mosaic making in Sicily was the age of the independent Norman kingdom in the 12th century. The Norman kings adopted the Byzantine tradition of mosaic decoration to enhance the somewhat dubious legality of their rule. Greek masters working in Sicily developed their own style, that shows the influence of Western European and Islamic artistic tendencies. Best examples of Sicilian mosaic art are the Cappella Palatina of Roger II, the Martorana church in Palermo and the cathedrals of Cefalù and Monreale.
Document 14: Renaissance: The Renaissance (UK: / rɪˈneɪsəns /, US: / rɛnəˈsɑːns /) is a period in European history, covering the span between the 14th and 17th centuries. It is an extension of the Middle Ages, and is bridged by the Age of Enlightenment to modern history. 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.
Document 15: Monte Rosa Hotel: The Monte Rosa is a hotel, located in the main street of Zermatt. It was frequented by the members of the Alpine Club, including Edward Whymper who made the first ascent of the Matterhorn in 1865. The hotel is named after the highest mountain near Zermatt, Monte Rosa.
