Cheomseongdae
From Free net encyclopedia
Template:Koreanname Cheomseongdae is an astronomical observatory in Gyeongju, South Korea. Cheomseongdae means star-gazing tower in Korean. Cheomseongdae is one of the oldest surviving observatories in East Asia, and one of the oldest scientific installations on Earth. It dates to the 7th century to the time of kingdom of Silla, which had its capital in Gyeongju. Cheomseongdae was designated as the country's 31st national treasure on December 20 1962.Template:Ref.
According to Samguk Yusa, Cheomseongdae was constructed under the reign of Queen Seondeok (632-647) near the capital of the kingdom. Cheomseongdae means "star gazing platform". The tower is built out of 362 pieces of cut granite which some claim represent the 362 days of the lunar year. Some surveys of the site have indicated that there are 366 blocks.Template:Ref It has 27 circular layers of stones (some associate it with the fact that Queen Seondeok was considered to be the 27th ruler of Silla) surmounted by a square structure. 12 of the layers are below the window level and 12 are above. There are 12 large base stones set in a square, with three stones on each side. These sets of 12 may symbolize the months of the year.
The tower is 5.7 meters wide at the base and 9.4 meters tall, and filled with dirt up to the level of the window. Its construction style parallels that used at the Bunhwangsa Temple in Gyeongju and was likely a product of contact with the Tang Dynasty of China, with which Silla's Queen Seondeok allied her country.
The Cheomseongdae is one of the oldest surviving observatory in East Asia, though some claim that Cheomseongdae was not suitable for astronomical observation. Others posit that it was used for astrology rather than astronomy, though during that era there was little differentiation between the two. Some scholars have argued that the Cheomsongdae's design was heavily influenced by Buddhism, noting similarities between its design and Mount Sumeru, the center of the world according to Buddhist mythology.
