In the study of these migrations, we find no more unanimity of interpretation than in other questions of these early times.[814] The Nahua peoples (Toltecs, Aztecs, Mexicans, or what you will), according to the prevalent views of the early Spanish writers, came by successive influxes from the north or northwest, and from a remote place called Tollan, Tula, Tlapallan, Huehue-Tlapallan, as respects the Toltec group,[815] and called Aztlan as respects the Aztec or Mexican. When, by settlement after settlement, each migratory people pushed farther south, they finally reached Central Mexico. This sequence of immigration seems to be agreed upon, but as to where their cradle was and as to what direction their line of progress took, there is a diversity of opinion as widely separated as the north is from the south. The northern position and the southern direction is all but universally accepted among the early Spanish writers[816] and their followers,[817] while it is claimed by others that the traditions as preserved point to the south as the starting-point. Cabrera took this view. Brasseur sought to reconcile conflicting tradition and Spanish statement by carrying the line of migration from the south with a northerly sweep, so that in the end Anahuac would be entered from the north, with which theory Bancroft[818] is inclined to agree. Aztlan, as well as Huehue-Tlapallan, by those who support the northern theory, has been placed anywhere from the California peninsula[819] within a radius that sweeps through Wisconsin and strikes the Atlantic at Florida.[820] The advocates of the southern starting-point of these migrations have been comparatively few and of recent prominence; chief among them are Squier and Bancroft.[821] * * * * *
