The Basin or Valley of Mexico is a highlands plateau in central Mexico roughly corresponding to modern-day Mexico City. Here, we are interested in the phase of its prehistory known as the Epiclassic or Late Classic period (c. 650-899 CE). In this period, Teotihuacan had diminished in size and lost its hold over the region; at the same time, none of the major centres at the time matched it: the populations of Cantona, Xochicalco, and Cacaxtla likely did not surpass 25-30,000. [1] Worship of the feathered snake became widespread throughout Mesoamerica, as indicated by the broad distribution of artistic representations of this deity or culture hero, and there was a renewed emphasis on human sacrifice in both ritual practice and artistic expression.

"Whereas no sites are documented as fortified or military observatories during the Formative and Classic periods, approximately one quarter of sites are during the Epiclassic and one-third of sites are during the Postclassic." [1]

"...[the armor]was very effective against slingstones which relied on impact rather than penetration, and this protection grew as atlatl fire forced slingers back to greater and less effective distances." [1]

Although domesticated dogs were present during this period, [1] [2] their function is unclear (food and/or hunting), [3] [4] and war dogs were unknown in Mesoamerica at the time of the Spanish Conquest; indeed, Hassig lists war dogs among the new military "technologies" the Spanish introduced to the region in the sixteenth century [5] [6] [7]
