patios and ballgame courts, but more surprising of all is to learn that, all visited in the site (3 km), and the structures available comprise only 10% of the total of this prehispanic city. It is assumed that water in this area was scarce, but did not limit construction of towering pyramids, housing spaces and narrow streets to maintain order in the different social standards that existed at that time, only two people can walk on the streets at the time because of narrow streets, in addition to street side walls for better control. The Earth Fertility Plaza is one of the most popular visits, because of phallic sculptures found, the two votive axes and all other material found, and is considered one of the most important findings. Cantona began declining as of 950 and 1000 and by 1100 was completely abandoned, without any current definition as to the reason why settlers migrated, although it was a prosperous and superbly constructed site. Chronology The history of Cantona is divided into several different phases of development spanning approximately 2,000 years, from around 1000 B.C.E. until the city was finally abandoned around 1050 C.E. Pre-Cantona (1,000/900 B.C.E - 600 B.C.E.) The first settlers began to occupy this area which would later form a vast city. Pottery shards from the pre-Cantona period tell us that the early settlers came from the Poblano-Tlaxcalteca Valley and the Tehuacan Valley, and later from the Gulf of Mexico and the East. At this time Cantona consisted of a few sparse settlements with no fortification or defined plan. Between 900 and 750 A.C., two villas occupied the center and southern portion of the area where the city would later develop, and one or two villages existed to the North or Northeast. Little is known about the architecture of this phase, although the city had not yet developed complex fortifications, walls or streets that would characterize later stages of development. Cantona began exploiting and trading in obsidian obtained from the nearby Zaragoza-Oyameles Mountains of northeastern Puebla. Obsidian was a valuable resource used for weapons, tools, and artifacts to conduct ritual auto-sacrfice. The Zaragoza-Oyameles obsidian source would ultimately turn Cantona into one of the largest and most prosperous cities in prehispanic Mesoamerica. In the late pre-Cantona period, between 750 - 600 A.C., the city began to develop joined housing, some streets in its interior, as well as paths to connect
