Damnazes is known to the Byzantine historian John Malalas as the father and predecessor of Tzathius, king of the Lazi. The anonymous Chronicon Paschale (Chron. Pasch. s.a. 522) renders his name as Zamnaxes. According to a genealogical hypothesis by Professor Cyril Toumanoff, Damnazes might have been a son of the Lazic king Gubazes I, who is known to have had his son as co-ruler 456.
