Abo of Tiflis (Arabic: أبو التفليسي, romanized: Abu al-Tiflisi; Georgian: აბო თბილელი, romanized: abo tbileli; c. 756 – 6 January 786) was a Christian martyr of Arab origin, who went on to practice his faith in what is now Tbilisi, the capital of present-day Georgia.
At the age of seventeen or eighteen, he found himself in Tbilisi, having followed Georgian Prince Nerses, the ruler of Kartli.
However, initially Abo was afraid to convert openly as eastern Georgia was under Arab rule; he only abandoned the Muslim habit of five-times prayers per-day and started praying in a Christian manner.
For political reasons, his prince had to seek shelter in Khazaria north of the Caspian Sea, an area which was not ruled by Muslims; Abo accompanied him, and was baptized there.
There in Abkhazia Abo zealously followed the Christian life of prayers and ascetic struggles, preparing himself for a future mission.
