The Maya did have extensive trading relationships with other cultures which led to cultural diffusion. From roughly 1000 A.D. to 1500 A.D., the Mayan civilization existed. During that time other cultures/civilizations were also present in the Yucatan, such as the Mixtec, Toltec, and Aztec. A few common themes between the Maya and those neighboring civilizations are sun-based calendars, figure-based religions, and thick history in art, especially pottery and stonework. A specific example of pottery and stonework is the Maya Polychrome ware, or painted pottery, and the Mixtec mosaics made of small, painted, squares of clay. It would make sense for the Mixtec to trade with the Maya to get polychrome for their mosaics. The two cultures would influence each other through this trade, creating cultural diffusion.
