Valarsaces was appointed king of Armenia by his brother the Parthian monarch, immediately after the defeat of Antiochus Sidetes (Moses Choren. l. ii. c. 2, p. 85), one hundred and thirty years before Christ. Without depending on the various and contradictory periods of the reigns of the last kings, we may be assured that the ruin of the Armenian kingdom happened after the council of Chalcedon, A.D. 431 (1. iii. c. 61, p. 312); and under Varanes, or Bahram, king of Persia (1. iii. c. 64, p. 317), who reigned from A.D. 420 to 440.
