"One will see reference in the translation to the four parts of Mexico Tenochtitlan, in the Nahuatl usually simply nauhcan, literally 'in four places.' Tenochtitlan was a complex altepetl consisting of four separate sub-altepetl, each large and complex in itself. The units are of the type that Chimalpahin calls tlayacatl altepetl in referring to his native Amaquemecan, but he never uses that word for the four parts of Tenochtitlan; indeed he gives them no specific appellation at all."
