But Huck - that is really interesting - thanks.
Well, that's only a rough - argumentative - overview. Well, and it follows the wisdom, that the origin of things is naturally simple, trivial, not hidden, open to all eyes ... just overlooked, cause the researched object is too much mystified, so that everybody is confused about it.
We've a sort of "original Tarot" in the writings of Cessolis, the most successful chess-book in 14th century. His idea was just, that ... additional to the already known specification of the chess officers ... also the pawn should have "personal character".
So they got professions, that the game knew 16 different figures (let's call it "natural Tarot content" or perhaps better "natural catalog") just to fulfill Cessolis' vision, that two imitated kingdoms had a meeting at the chess-board.
... .-) ... Likely this had been an imported Mongolian idea. Cessolis had to do with inquisition and Marco Polo was a prisoner ... so possibly on this way. But it doesn't matter, possibly Cessoilis had an own idea, why not, or he knew an already existent European tradition. The idea is not very complicated and natural.
What we have, is, that in Mongolian chess-rules the pawn specification also appears and in these it has game-rule-function, which isn't the case for Cessolis, to whom this is only moralization.
If a specified pawn reached the promotion line, he became his master officer, so, as if a Knight-pawn would become a knight in the European version (not a Queen as nowadays usual).
That's for instance such a specified pawn, the messenger or player, a sort of catalog-card. He had his position at the Queen-side before the rook.
Perhaps the dice are there, cause the variant to play chess with dice was stronger than expected in research.
