According to Jean-Louis Cazaux's page, there are multiple manuscripts describing it that differ in the particulars, particularly in the initial array, but also sometimes with a different board (size, presence of citadel squares) or adding pieces. It's not clear if the discrepancies are due to errors (and if so, which manuscripts are erroneous, possibly all in different respects) or if the game itself was in flux or played in multiple variations.
