Abkhazia in antiquity
The written history of Abkhazia largely begins with the coming of the Milesian Greeks to the coastal Colchis in the 6th-5th centuries BC. They founded their maritime colonies along the eastern shore of the Black Sea, with Dioscurias being one of the most important principal centers of trade with the neighboring tribes, that of slaves not excluded. This city, said to be so named for the Dioscuri, the twins Castor and Pollux of classical mythology, is presumed to have subsequently developed into the modern-day Sukhumi. Other notable colonies were Gyenos, Triglitis, and later Pityus, arguably near the modern-day coastal towns of Ochamchire, Gagra, and Pitsunda, respectively.
The peoples of the region were notable for their number and variety, as classical sources testify. Herodotus, Strabo, and Pliny appreciate the multitude of languages spoken in Dioscurias and other towns. The mountainous terrain tended to separate and isolate local peoples from one another and encouraged the development of dozens of separate languages and dialects complicating the ethnic makeup of the region. Even the most well-informed contemporary authors are very confused when naming and locating these peoples and provide only very limited information about the geography and population of the hinterland. Furthermore, some classic ethnic names were presumably collective terms and supposed considerable migrations also took place around the region. Various attempts have been made to identify these peoples with the ethnic terms employed by classical authors. Some scholars identify Pliny the Elder’s Apsilae of the 1st century AD and Arrian’s Abasgoi of the 2nd century AD with the probable proto-Abkhaz- and Abaza-speakers respectively, while others consider them proto-Kartvelian tribal designations. The identity and origin of other peoples (e.g., Heniochi, Sanigae) dwelling in the area are also disputed. Archaeology has seldom been able to make strong connections between the remains of material culture and the opaque names of peoples mentioned by classical writers. Thus, controversies still continue and a series of questions remain open.
According to The Georgian Chronicles, the first inhabitants of what is now Abkhazia and the whole western Georgia were Egrosians, the descedants of Egros son of Togarmah, grandson of Japhet, son of Noah, who came from the land known as Arian-Kartli.
