How many bishops were actually in the room on the first day? I went and counted, as far as anyone can count from the records, and it's barely a dozen — the sources disagree here, as they tend to. By the time it closed at the end of February 870 the figure had passed a hundred, which is the number usually given, and that number quietly swallows five months of people arriving late, being admitted, being disputed over, and in a few cases being admitted and then disputed over. Ten sessions. Twenty-seven canons at the end of it.
The Greek acts didn't really survive; what we have is mostly a Latin version, made by Anastasius, librarian of the Roman church, who was in Constantinople while it sat and brought his copy back west with him. Five months of argument in one language reaches us because a librarian packed it in the other.
The image question had a long afterlife in the workshops, Miriam — painters kept to the agreed poses and the agreed gestures for centuries after, not from want of invention but because what a figure did with its hands had been argued over by people like these. A panel in Constantinople is a theological position with egg and pigment on it.
Anastasius translated very literally, almost word under word, which made for clumsy Latin and is exactly why it's useful; scholars can sometimes see the Greek standing behind his sentences. He did the same service for other councils too — a librarian's instinct, carry the copy, worry about the style later.
