Àger Rock Crystal Chess Pieces

Chess in rock crystal: Islamic pieces of the Fatimid period, cut with vertical ribs and kept for centuries in the treasury of the collegiate church of Sant Pere d'Àger in Catalonia, now in the Museu de Lleida. A rock crystal set of 96 pieces is named in the 1068 will of Arsenda, wife of the Catalan lord Arnau Mir de Tost. Lit in a dark case, the pawns and the taller ribbed major pieces look like ice, and the shapes still follow the abstract Islamic pattern rather than tiny figures.
