Thanks Ana for this matching postcard and cover!Unique to the Vinicko Kale Fortress (shown above) are these Latin inscribed 5th century Christian terracotta icons, first unearthed in 1978. Issued on stamps 18 years later are 4 of the 50 intact tiles encompassing over 15 scenes from the Old and New Testament. The upper right stamp shows Christopher and George, bottom left is Caleb and Joshua. The icons were likely manufactured locally as their ceramic signature matches that of the clay in the area. A hundred of these fragments have been found in architectural fill. Where in the Fortress were the intact icons found?
