Риони
The Machelones () (Machelônes, Machelonoi; ) were a Colchian tribe located to the far south of the Phasis (modern-day Rioni River, western Georgia). There are several references to them in Classical sources. This group may be the Machorones of Pliny (NH 6.4.11) who placed them between the Ophis (modern Of, Turkey) and Prytanis rivers.
