Three stone slabs were found by Romanian archaeologist Nicolae Vlassa, in mid 20th century (1961) in Tărtăria, somewhere in noways Transylvania, Romania, historical land of Dacia, inhabited by Getaes, which were a population who may have been related to the Thracians. One of the slabs contains 4 groups of pictographs divided by lines. Some of the characters are also found ancient Greek, but also in Phoenician, Etruscan, Old Italic and Iberian. The origin and the timing of the writings are widely disputed, because there are no precise evidence in situ, the slabs cannot be carbon dated, because of the bad treatment of the Cluj museum. There are indirect carbon dates found on a skeleton discovered near the slabs, that certifies the 5300-5500 BC period. However, the presence of influences of Greek, Phoenician and Etruscan in the writings, make it unlikely that they date from this period. Other hypothesis are that the slabs are imported from Cyclades islands, because of other artifacts found in the same site.
