 Among modern scholars it is a matter of debate whether the Aztec narratives of Toltec history should be given credence as descriptions of actual historical events.While all scholars acknowledge that there is a large mythological part of the narrative some maintain that by using a critical comparative method some level of historicity can be salvaged from the sources, whereas others maintain that continued analysis of the narratives as sources of actual history is futile and hinders access to actual knowledge of the culture of Tula, Hidalgo.Other controversy relating to the Toltecs include how best to understand reasons behind the perceived similarities in architecture and iconography between the archaeological site of Tula and the Maya site of Chichén Itzá – no consensus has emerged yet about the degree or direction of influence between the two sites.
