'On y monte, du côté de l'ouest, par une rampe tracée de gauche à droite pour le premier étage, de droite à gauche pour le second, et ainsi de suite jusqu'au dernier.' Lenoir, in Antiq. Mex., tom. ii., div. i., p. 26; Klemm, Cultur-Geschichte, tom. v., p. 157.

[IX-4] Dupaix, 3d exped., p. 5, pl. i., ii., fig. 1-3; Kingsborough, vol. v., pp. 285-6, vol. vi., p. 467, vol. iv., pl. i., ii., fig. 1-3. According to Dupaix's plate the sides and summit platform are covered with plaster. Kingsborough's plate omits the coating of plaster and shows the remains of a ninth story. A scale attached to the latter plate would indicate that the pyramid has a base of 150 feet and is about 75 feet high. Lenoir, p. 69.

Kingsborough's plate makes the blocks of stone much smaller than the other, shows no plaster, and represents the walls of the summit building as still standing. Kingsborough also incorrectly translates 'antes de San Andrés,' 'formerly San Andrés.' Klemm, Cultur-Geschichte, tom. v., p. 157.

[IX-12] 'The large mound of earth at Cholula which the Spaniards dignified with the name of temple, still remains, but without any steps by which to ascend, or any facing of stone. It appears now like a natural mount, covered with grass and shrubs, and possibly it was never anything more.' Robertson's Hist. Amer., vol. i., p. 269. 'A le voir de loin, on seroit en effet tenté de le prendre pour une colline naturelle couverte de végétation.' 'Elle est très-bien conservée du côte de l'ouest, et c'est la face occidentale que présente la gravure que nous publions.' Humboldt, Vues, tom. i., pp. 104-5.
