This term, the obliquity of the ecliptic, refers to the angle between the plane of the earth’s orbit and that of the celestial equator, equal to approximately 23 degrees and 27 minutes at the present. The tilt of the obliquity, however, changes very slowly over great periods of time. Its cyclic variation ranges between 22 degrees, 1 minute and 24 degrees, 5 minutes over a period of 41,000 years or 1 degree in 7000 years (this cycle is not to be confused with the better known precessional cycle of 25,920 years or 1 degree of movement every 72 years). The figure that Posnansky determined for the obliquity of the ecliptic at the time of the building of the Kalasasaya was 23 degrees, 8 minutes, and 48 seconds. Based on these calculations, Posnansky was thereby able to date the initial construction of the Kalasasaya and Tiahuanaco to 15,000 BC. This date was later confirmed by a team of four leading astronomers from various prestigious universities in Germany.
This initial construction date, being vastly older than that deemed possible by the prevailing paradigm of history, was (and still is) ridiculed by mainstream archaeologists and prehistorians. But it is not so easy to dismiss Posnansky’s findings as there are other mysteries concerning Tiahuanaco that seem to confirm the great antiquity of the site. Among these are the ancient myths of Tiahuanaco (from throughout the Andean region) that tell of its founding and use in a pre-flood time; the scientific studies that prove a cataclysmic flood did indeed occur some twelve thousand years ago; the utensils, tools, and the fragments of human skeletons that are mixed in with the deepest layers of the flood alluvia (indicating human use of the site prior to the great flood); and the strange carvings of bearded, non-Andean people that are found around the site (replete with sculptural and iconographic details that are completely unique in the western hemisphere).
