Scientists from Russia and the Netherlands using the new radiocarbon method was able to determine the exact date of the Foundation of the ancient fortress Por-Bazhin. The opening allowed to know what in the taiga of southern Siberia on the island in lake Tere-Khol was built the giant structure.
One of the mysteries of mud-brick fortress in Tuva is that after construction it was abandoned and the people. Paleogeography MSU in 2009 conducted a dendrochronological and radiocarbon Dating found in the base of the fortress of trunks of larch. It turned out that the Por-Bazhin was not built in 757 by order of the head of the Uyghur Khaganate Eletmish of bilge Kagan, but 20-30 years later.
Professor of geographical faculty of Moscow state University Andrey Panin decided to clarify the exact Dating of the fortress with open source, Japanese scientists “events Miyake” – an abnormal lowering glow of the Sun in 994 year.
– We sent to Groningen in two of our saw cut, and in one of them, in the third ring from the bark, it was discovered that the “event Miyake”. And the youngest ring on the cellular level allowed us to determine that the tree was cut down in the summer. Thus was established not only the year, but the season of start of construction – summer 777-th, and graduated in the year 778,” – said the scientist.
This fact radically changed the ideas about the historical past of the fortress. Por-Bazhin was founded under a different ruler, Bogu-Kagan, who accepted Manichaeism. However, in 779 the religious upheaval and the ruler was killed, and the new Manichean monastery were not wanted by local people-the Gentiles.
