On the territory of Lazarevsky district of Sochi in ancient times lived in different tribes. Ubykh people, Shapsyghs, Circassians, Circassians. Lived, lived until the General Lazarev not annexed these territories to the Russian Empire. That's why the village is Lazarevskoe. But in my opinion statue does not belong to these tribes. This is most likely the earlier Scythian-Sarmatian period. On the grounds of the city often find dishes, household items, figurines, ornaments of this period. My own are ten different pitchers of this era, as well as arrowheads and spears found during excavations near Sochi. Also under Lazarevskiy are several places of worship - dolmens, so that in ancient times in the Black Sea civilization was in motion
I think that your sculpture does not apply to Tibet. This is most likely Scythian-Sarmatian product.
