[1] The name "Rev" derives from Middle Iranian Rēw, itself from the Avestan adjective raēva, meaning "rich, splendid, opulent".
[2] He is known exclusively from the medieval Georgian annals which make him a son of the king of Armenia,[1] whom the historians Cyril Toumanoff and Stephen H. Rapp identifies with the Arsacid, Vologases II (r. 180–191).
[3][4] Rev was enthroned by the rebellious Iberian nobles who deposed his maternal uncle, Amazasp II, last of the Pharnabazids.
Rev is reported to have married a "Greek" princess Sephelia who is said to have brought an idol of Aphrodite to Iberia, but there is no indication of a local cult of this Greek goddess having ever existing.
Toumanoff illustrated that this sobriquet is a direct translation of dikaios, an epithet frequently used in the titulature of the Arsacid kings of Parthia.
