History of chess
The Afrasiab finds include seven chess pieces. They are heavily worn, but they include: two foot soldiers with shields and short swords (= our pawns); a war elephant with chain armour and a rider in full battle-dress (= our bishop); a visier (= our queen) with two horses with armed rider; two mounted riders with sword and shield (= knights); and the Shah, on a three-horse chariot, holding a mace-like symbol of power (= our king). That is five out of the six types of piece, and completely convincing as a chess set. The rukh (rook) is also known: it features a three-horse chariot with two men, one driving, and the other armed with sword and shield.p61–62
