What did the European chess look like around 12-13th century

Hello, my question is as the subject states. I kept looking at different websites trying to find an answer but cannot seem to find a definitive one. 

Chess first appeared in Europe in Moor Spain where it was brought by Muslims. There is an idea more or less of what Muslim sets looked like. They tended not to have images or outlines of the horse since. Some sets I saw look like various onion bulbs or mushrooms if different heights and widths. 

When the Christian Europeans started to like Chess they changed some rules which made the game more interesting. Queen became the best piece, bishop was given the option to as far along their diagonal as they wanted, pawns could do a double start move, and castling was introduced. (Seems the closest to pre European rule change is the modern Makruk chess.)

Surprisingly for me, when I try to find what the chess figures, pieces, chessmen looked like during and after this change was made I cannot find any information whatsoever.

Could someone who knows give me a link to any articles or photos of these pieces either in art, paintings, or preserved ancient pieces?

Thanks

I think the average player went 1.e4 and was then slain with a sword for being a heathen and died aged 20. 

Yea and never even got the chance to sacrifice their horses.

Thank you! This actually provides a good explanation. I am so thankful to whomever designed more elaborate chess sets such as St George, Regence, and to Staunton. Makes me appreciate Staunton’s achievement of practical design.

In 12th to 13th century, chess used to called Shatranj which was imported from middle east, the rule was way more different (e.g : Bishop moves only 2 step diagonal, Queen moves only 1 step diagonal, no Pawn move 2 steps forward in first move, no en passant and castling)

If you want to see more pictures of the chess pieces used back then, check out this website. It has a good overview. http://history.chess.free.fr/first-european.htm

The first pieces used in Europe were of the abstract Muslim style. However, the Europeans soon started to "decorate" these pieces with motives and ornaments. I wrote a short article on the question how chess pieces changed over time, which also touches on this aspect.

that very interesting

I know this is an old thread, and the source I used has already been mentioned in this thread, but below I compiled some of the prominent chess set designs from the 13th to 17th century in Europe.
