the Apostle sent to preach the Christian Gospel among the "Indians", although he provides nothing more than circumstantial evidence of any contact between the hemispheres. The later debate about the nature of the Toltec culture goes back to the late 19th century. Mesoamericanist scholars such as Mariano Veytia, Manuel Orozco y Berra, Charles Etienne Brasseur de Bourbourg, and Francisco Clavigero all read the Aztec chronicles and believed them to be realistic historic descriptions of a pan-Mesoamerican empire based at Tula, Hidalgo. This historicist view was first challenged by Daniel Garrison Brinton who argued that the "Toltecs" as described in the Aztec sources were merely one of several Nahuatl-speaking city-states in the Postclassic period, and not a particularly influential one at that. He attributed the Aztec view of the Toltecs to the "tendency of the human mind to glorify the good old days" and the confounding of the place of Tollan with the myth of the struggle between Quetzalcoatl and Tezcatlipoca. Désiré Charnay, the first archaeologist to work at Tula, Hidalgo, defended the historicist views based on his impression of the Toltec capital, and was the first to note similarities in architectural styles between Tula and Chichén Itza. This led him to posit the theory that Chichén Itzá had been violently taken over by a Toltec military force under the leadership of Kukulcan. Following Charnay the term Toltec has since been associated with the influx of certain Central Mexican cultural traits into the Maya sphere of dominance that took place in the late Classic and early Postclassic periods; the Postclassic Mayan civilizations of Chichén Itzá, Mayapán and the Guatemalan highlands have been referred to as "Toltecized" or "Mexicanized" Mayas. The historicist school of thought persisted well into the 20th century, represented in the works of scholars such as David Carrasco, Miguel León-Portilla, Nigel Davies and H. B. Nicholson, which all held the Toltecs to have been an actual ethnic group. This school of thought connected the "Toltecs" to the archaeological site of Tula, which was taken to be the Tollan of Aztec myth. This tradition assumes that much of central Mexico was dominated by a Toltec Empire between the 10th and 12th century AD. The Aztecs referred to several Mexican city states as Tollan, "Place of Reeds", such as "Tollan Cholollan". Archaeologist Laurette Séjourné, followed by the historian Enrique Florescano, have argued that the "original" Tollan was probably Teotihuacán. Florescano adds
