Inspired by this beautiful version of the Serbian Flag federalrepublic.deviantart.com…
with the Serbian Cross – Ocilo (pronounced Otschilo or sometimes Otzilo), I was able to remember that I've seen a 3500 years old symbol like it, on a female "bell shape" dress idol from an incineration necropola belonging to Gârla Mare-Cârna Culture from 1550-1500 BCE!
The presented photo (left) is at page 56 from the XI-th grade romanian History Manual called "Istoria Romanilor -din cele mai vechi timpuri pana la Revolutia din 1821" (The History of Romanians - from the oldest times until The 1821 Revolution);

This culture was named after the villages called Gârla Mare (in Mehedinți County) and Cârna (in Dolj County) from South-Western romanian region of Oltenia. It follows the middle Danube river course (inside and W-E outside Danube Gorge on both shores) in SW Romania but also in NW Bulgaria and and East Serbia and it is known for the incineration necropolas (from Cârna, Ostrovul Corbului and Balta Verde) having common elements with the Verbicioara/Dubovac-Žuto Brdo Culture and intersecting the Vattina Culture.
Knowing that the romanian-serbian-bulgarian-greek-macedonian-albanian traditional national folk costumes have an incredible symbolistic inheritance from thousands of years old local Balkano-Carpathian Danube pelasgo-thracian culture and spirituality (examples:www.youtube.com/watch?v=NvSDR6… www.youtube.com/watch?v=G8wR9p…
), same case for the Byzantine Christian Ortodox religion and empire, I have no doubt that in these areas are still people wearing traditional clothing and making clay pots with similar symbols.
*Edited (2013-02-09): recently I found out that the symbol in question is also part of Vinča culture writing system, check the 0:57 moment from this video (third row from above, fifth symbol from the left): www.youtube.com/watch?v=5en5i3…
