Turn 180 Religious victory. Immense frustration at finish date as it took 35 turns to find and convert the last AI (Norway):- closest I have come to rage-quit a Civ game in many years. From turn 100 I went on a conquest of Pericles Greece (the only serious religious challenger), then spammed Apostles (getting around 200 Faith per turn at this point) and used Proselytizer / Translator pairs to stamp out other foundling religions. I made contact with France at turn 130 and, after switching research to Cartography, sailed over to convert her heathen flock. But where was the last AI? Assuming (incorrectly due to mounting frustration) that I had erased all other religions, I spammed triple-strength Translator Apostles and sent them to all corners of the world, but I seem to have missed my AI quarry at least twice by taking wrong turns when virtually upon them. I eventually found Harald of Norway surrounded by hordes of barbarians in the far NE corner of the map. It then took over 25 turns to bring sufficient forces to suppress the barbarians and allow my Apostles to do their work. Harald actually had founded his own religion and spread it to all his cities and I had the wrong combination of Apostles to deal with this quickly:- a combination of Heathen Conversion / Proselytizer would have saved me over 20 turns. My initial Apostle escorts struggled to make headway through the barbarian hordes:- poor old Harald!
