possibly related to old ideas about shamanism and death as a passage into a watery afterlife.
a story on the site today, written by a reporter who visited the local museum and was blown away by what he saw. He reports on the new discoveries about the site, made through studying ancient DNA from four skeletons:
Two were identifiable as Near Eastern farmers. And studies of the chemistry of their bones show that they had not grown up at Lepenski Vir, but were migrants from elsewhere. Another had a mixed hunter-gatherer/farmer heritage and had eaten a diet of fish. Another had hunter-gatherer heritage.
The dating of the skeletons showed a range. The one with mixed heritage was from 6070 B.C.E., or about 8,000 years ago. The farmers were dated as 6200-5600 B.C.E. And the hunter-gatherer probably earlier than the others.
