The Georgian underwater artefacts discovered on the east coast of the Black Sea can be chronologically assigned to the Byzantine period.
A concave waist amphora 6th – 7th century
Place of discovery: Choloki-Natanebi water area
Preserved in the Ajara Museum – Archaeological Museum of Batumi
It is completely preserved in Batumi Archaeological Museum. It has a clearly defined ring-shaped mouth and a low cylindrical neck. The upper half of the body is rounded and the continuation is slightly concave. The lower half of the conical shape ends with a slightly offset rounded bottom. The upper part of the flat ear is attached below the mouth, and the lower part – is in the shoulder area. Similar to the Colchi amphorae from the Hellenistic period, a fingerprint-like impression can be observed. The clay is brown.
It contains mixtures of pyroxene and white limestone. The form emerged in the 5th century BC and can be found on many monuments on the east coast of the Black Sea as well as on the north, west, and south coasts of the Black Sea. According to the analysis of the amphorae found in Demirj, a settlement near Sinop, they are an imitation of Colchian amphorae and are therefore called pseudoColchian amphorae.
