Note 770 — Chapter XVIII · ARCHITECTURE AND DWELLINGS OF THE NAHUAS.
Reading edition
Brasseur de Bourbourg, Hist. Nat. Civ., tom. iii., p. 659, states that three sides of the platform were protected by a balustrade of sculptured stone, and this is not unlikely when we consider the slippery nature of the floor and the dizzy height. See Torquemada, Monarq. Ind., tom. ii., p. 141; Las Casas, Hist. Apologética, MS., cap. xlix., cxxiv., and note 75 on polished floors. Carbajal Espinosa, Hist. Mex., tom. i., p. 664, states that the summit was paved with marble.
