"In 2008, a team of archaeologists and conservators from Poland and Czech Republic undertook maintenance work on a remarkable collection of anthropomorphic 11th and 12th century AD figures at the Veliklanadolskyi Forest Museum in Eastern Ukraine." Source: Past Horizons.
"Anthropomorphic stelae such as these were erected as memorials to the dead and are found in both individual burial and cemetery contexts dating from the Neolithic right through to the Middle Ages."
Note: These stelae open a window into deep barbarian territory. "Polovtsian" refers to the Polovsti, the Russian name for the Cumans or Kumans, a "nomadic East Turkic people, identified [confederated?] with the Kipchaks..," according to the Columbia Electronic Encyclopedia via the Free Dictionary. The Polovsti apparently took part in the resistance to the Mongol invasion in the 12th century AD.
There are dozens of archaeological sites in the Ukraine. Let's hope that they survive the current conflicts. The video below shows how imaging techniques were used in 2008 to bring out the inscriptions on an (unrelated) stele found in the Ukraine.
