It will now be seen how closely this agrees with the description given by Don Lucas Alaman, one of the best modern authorities on the topography of the City. (Disertaciones, by Don LUCAS ALAMAN, 1844. Octava Disertacion, vol. ii. p. 246.) “We must now fix the site occupied by the famous Temple of Huichilopochtli[4]. As I have stated above, on the Southern side it formed the continuation of the line from the side walk (acera) of the Arzobispado towards the Alcaiceria touching the front of the present Cathedral. On the West it ran fronting the old Palace of Montezuma, with the street now called the Calle del Empedradillo (and formerly called the Plazuela del Marques del Valle) between them, but on the East and North it extended far beyond the square formed by the Cathedral and Seminario, and in the first of these directions reached the Calle Cerrada de Sta. Teresa, and followed the direction of this last until it met that of the Ensenanza now the Calle Cordobanes and the Montealegre.” THE GREAT TEOCALLI OF HUITZILOPOCHTLI. The general description of the ancient City by eye-witnesses does not enable us to locate the position of the great Teocalli with exactness, but further information can be gained by examining the allotment of Solares or City lots to the Conquerors who took up their residence in Mexico and to religious establishments; these allotments can in some instances be traced through the recorded Acts of the Municipality. (7th Disertacion, p. 140. Don LUCAS ALAMAN.)

Teresa on the side walk which faces South.
