Sitovo inscription

The Sitovo inscription is an inscription that has yet to be satisfactorily translated. It was discovered in 1928 by an archaeological expedition led by Alexander Peev on the wall of a rock shelter near the village of Sitovo, close to Plovdiv, Bulgaria. In 1943 Peev, an active anti-fascist, was executed by firing squad on suspicion of sending a coded message to the Soviet Union, after he sent an example of the text to Soviet archaeologists, in the hope that they could decipher its meaning. The inscription was published in 1950 by Z. R. Morfova.
