probably the answer is unknown, but ill ask anyway.
So i tried fiddling around with the world buildr, to get a sort of historical medittaranean (like carthage, rome,spain, byzantium, ottomans and greece o the right places). but it proved too much hassle for my limited modding skills, cause you also hav the citystates and so on. Im quite surprised nobody made a meditteranean map with historical start positions in the workshop (thee is only one, but it isnt highly rated, and it seems its still a work in progress)
When i selected carthage and meditteranean, after a few retries, i landed on the historical carthage spot. Will the game (after an x amount of tries), land me on the byzantium/constantinople spot?
