that the Mayan sources refer to Chichén Itzá when talking about the mythical place Zuyua (Tollan). Many historicists such as H. B. Nicholson (2001 (1957)) and Nigel Davies (1977) were fully aware that the Aztec chronicles were a mixture of mythical and historical accounts; this led them to try to separate the two by applying a comparative approach to the varying Aztec narratives. For example, they seek to discern between the deity Quetzalcoatl and a Toltec ruler often referred to as Topiltzin Ce Acatl Quetzalcoatl. Toltecs as myth Since the 1990s, the historicist position has fallen out of favor for a more critical and interpretive approach to the historicity of the Aztec mythical accounts based on the original approach of Brinton. This approach applies a different understanding of the word Toltec to the interpretation of the Aztec sources, interpreting it as largely a mythical and philosophical construct by either the Aztecs or Mesoamericans generally that served to symbolize the might and sophistication of several civilizations during the Mesoamerican Postclassic period. The Nahuatl word for 'Toltec', for example, can mean 'master artisan' as well as 'inhabitant of Tula, Hidalgo', and the word Tollan (known as Tula in modern times) can refer specifically to Tula, Hidalgo, or more generally to all great cities through meaning 'place of the reeds'. Much of the questioning of these Aztec narratives is due to the lack of archaeological evidence to support them. Aztec accounts tell that the Toltec discovered medicine, designed the calendar system, created the Nahuatl language. More broadly, the Aztec traced most of their own societal achievements to the Toltec and their city Tollan, which was idolized as the epitome of state civilization with an enormous influence in the surrounding region. However, Tula—the site attributed with this Tollan—lacks much of the splendor that the Aztecs describe. For example, Tula was mainly built out of the relatively soft and unimpressive adobe brick, and while Tula certainly was a major regional city in its time, it was minuscule both in population and in influence in comparison to both its predecessor, Teotihuacan, and its Aztec descendant, Tenochtitlan. Additional material remains at Tula, such as the destruction of Toltec buildings and monumental art coinciding with the arrival of Aztec ceramics, suggest that the Aztecs' reverence of the Toltec might have been mostly propagandistic, intentionally overexaggerating the previous culture to use it as a steppingstone for their own.
