The Georgian Chronicles
The Armenians did not allow Bak’ar to rule, for they wanted to enthrone the son of Trdat’s daughter [Salome]. Bak’ar took  refuge in Iran, giving the country to them. To P’eroz he gave from Shamshoylde to the head of Ashots’k’. Similarly he sent protests to Byzantium (“Greece”) and mustered troops from all parts. He fought the Armenians in Jawaxet’, driving them out. [g69] Then Bak’ar reigned [Aspacures II/ Varaz-Bakur I, 363-365], through the might of the Byzantines and Iranians. He obtained a document from Salome and her son stating that they would not seek the throne unless Bak’ar’s line was extinguished. He gave them Kuxet’ and set him up as prince of Risha. He himself remained firm in the faith and converted many of the Caucasians to Christianity. He built a church at Tsilkan and increased the clergy and deacons. He died in peace and was buried near his brother. Then his son, Mirdat [Mithridates/Mihrdat III, 365-380, diarch 370-378], ruled.
