Geoarchaeology of Phasis (Georgia)

The City of Phasis is located on the East coast of the Black Sea (Georgia). The location of the biggest and most successful of the colonies established by Ionian Greeks is still not known, a subject that has attracted interest from scholars for almost two hundred years. Based on written sources, geomorphological and archeological data, it is assumed that, due to tectonic and geomorphological changes, part of the ancient settlement/cultural layers dating back to the 1st mill. BC are below current sea level. These two changes mean that the present landscape is completely different to the 1st mill. BC situation. This observation is significant in resolving Phasis’s location. We report that: 1. The Greeks did not establish the city of Phasis adjacent to a lake. 2. The early city was located north of the river. 3. Early Phasis (6th-4th c. BC) is consistent with the settlement of Sagvichio or east of it.
