The Georgian Chronicle
occupies an unusual position among Armenian historical sources. Unlike the majority of Armenian literary sources, this work was not originally composed in Armenian. The original was written in Georgian in separate sections by several individuals between the 6-13th centuries. Sometime in the late 12th or early 13th centuries, an unknown cleric translated or abridged the then extant Chronicle into classical Armenian. It is this medieval Armenian rendering which is translated here. The Chronicle describes the history of Iberia/Georgia, Armenia's northern neighbor, from legendary times to the 12th century, and is a rich source of unique information on such topics as Caucasian ethnography, Armeno-Georgian relations, the history of Iran, the history of the Jewish community of Georgia and its role in the Christianization of the country; the birth of Islam, and the coming of the Saljuqs. http://rbedrosian.com/gc1.htm
Interesting bit on the autocephaly of Georgia:
And they came to the borders of Armenia and Byzantine lands. Because Leo, the Byzantine general, was with them with many troops, he went to his own country, taking emissaries [g89] with him [requesting] that they send the emperor's daughter as a wife for Vaxt'ang and that they ordain Petros kat'oghikos of Iberia, and Samuel as bishop. The emperor and the patriarch of Constantinople sent the priest Petros and the cleric Samuel to Antioch to be ordained there, "since", they said, "that is your diocese." Fulfilling the request, they sent  them back to Iberia. Now king Vaxt'ang went to K'art'li, and his son Dach'i and all the didebuIs ["glorious lords", Arm. p'arawork'n "glorious ones"] of Iberia came before him and greatly rejoiced as he entered Mts'xet'a. But as soon as bishop Mik'ayel learned that a kat'oghikos and a bishop were coming to Iberia against his will, he was vexed. On a pretext he rebuked Vaxt'ang [claiming] that he had worshipped fire. The king swore [oaths] and beseeched him, [saying]: "Christ is my true God. Do not condemn me falsely." But the bishop would not listen, and he cursed and excommunicated [Vaxt'ang]. The king said: "Although I am innocent of that thing, I have other sins before the Lord and therefore it is fitting that I humble myself before him." So he went and threw himself at the bishop's feet, kissed [them] and requested pardon. But the latter drew back his foot, struck the king on the mouth, and knocked out a tooth. Taking his tooth, the king said: "This is the work of my sins and of satan who raised you up against me, for you do not follow your commandment which says, 'Destroy not the broken reed' and 'Do not snuff out the wick which is almost extinguished.' Rather, you envy Petros and share in the jealousy of Judas." He sent him to the patriarch of Constantinopletogether with the tooth so that he would try him without bias. Seeing Mik'ayel, the patriarch said to him: "Like Judas, you greedily fought with the church and spilled blood, and from the king's mouth with your foot at that, and you pulled down the structure of God. Now you are unworthy of the priesthood, and worthy of  the death of your lord. Why did you not heed Paul, who said: [g90] 'Obey the king', and also 'Pray for the king, otherwise know that it is not in vain that he puts the sword to work.'" [The patriarch] immediately sent Mik'ayel into exile. http://rbedrosian.com/gc5.htm
The patriarch of Antioch, while ordaining Petros as kat'oghikos also gave him twelve bishops. [Thereafter] they went first to Constantinople where they received numerous gifts and the emperor's daughter, Helen (Heghine), and thence they went to Vaxt'ang. And the country was gladdened. The kat'oghikos sat at the church of Sion, in Mts'xet'a, which Vaxt'ang had built, and Samuel resided at the bishop's palace of Mts'xet'a. One bishop was stationed in Klarchet', one in Artahan, one in Jawaxet', one in Manklis, one in Bolnis (Bawghnis), one in Risha, one at the place named Saint Nino above the gate of Ujarma, one in Jeram, one in Ch'elt', one for two churches, Xornoyboj and at Agarak opposite Xunan. Vaxt'ang built a church at Nik'oz over the martyrium of Razhden, the Iranian nourisher of Vaxt'ang's first wife, [a man] who believed in Christ, was persecuted for the faith by the Iranians, but did not renounce Christ. They killed him for his good confession in the glory of Christ God, and the seat of a bishop was located on the site of his martyrium. Now Vaxt'ang had three sons and one daughter from [his wife] Helen. Then Vaxt'ang  dwelled at Ujarma, giving the greater part of the country [g91] to his senior son, Dach'i, and he married Xorandze, his senior sister, to the Armenian bdeshx, Bakur.
Note: the granting of the 12 bishops was to make the Catholicos fully ennabled to act as an autocephalos Church.
