Sofia (Bulgaria), August 29 : A stone clock from the first Bulgarian kingdom has been discovered, among other findings, near Mogila village, Kaspichan municipality, in Bulgaria.
According to a report in www.news.bg, some Bulgarian citizens accidentally came across two stone blocks near a Proto-Bulgarian fortress, out of which one portrayed a "stone clock" or "stone calendar".
The fortress is a part of the system, constructed for the defense of the capital Pliska. It closely resembles the Madara fortress, but is considerably smaller.
At the initial investigation, enormous treasure-hunter decays could be seen, reaching a depth of 4 meters.
Up to this moment, no regular archeological studies have been carried out, but just on-foot surveillance by the late Professor Rasho Rashev.
Typical Proto-Bulgarian graffiti are inscribed in one of the blocks, showing horsemen with their armory. Several horses and a central figure of a horseman holding a long lance can be clearly seen.
The other stone block portrays a "stone clock" or a "stone calendar".
This monument represents a semicircle, divided into 10 equal parts, plus two smaller parts marking its beginning and end.
On the better-preserved part, the Greek letters "alpha", "beta", "gamma", "delta" and "eta" can be seen, which define each of the equal parts.
A Medieval cross is inscribed in the center, marking the central axis of the "clock".
According to experts from the National Historic Museum, such types of monuments are extremely rare for the early Medieval Age.
