Mr. Bancroft has greatly facilitated the comparison of the lists of stations as given by different authors, in a note of great length on pp. 322–4, thus presenting to the eye at a glance the diversity of opinion which meets the reader of this subject. As an example, we select two or three of the itineraries, simply to show the wide range that opinion has taken on the subject. According to Veytia, the tribes left Aztlan in I Tecpatl, 1064 A. D., and one hundred and four years afterwards reached Chicomoztoc, where they dwelt nine years; the subsequent stations and the duration of their sojourn in each as follows: Cohuatlicamac three years, Matlahuacallan six, Apanco five, Chimalco six, Pipiolcomic three, Tollan six, Cohuactepec (Coatepec) three, Atlitlalacayan two, Atotonilco one, Tepexic five, Apasco three, Tozonpanco seven, Tizayocan one, Ecatepec one, Tolpetlac three, Chimalpan four, Cohuatitlan two, Huexachtitlan three, Tecpayocan three, Tepeyacac (Guadalupe) three, Pantitlan two, and thence to Chapultepec, arriving in 1298, after a journey of one hundred and eighty-five years, reckoning an additional forty-nine years for their stay at Michoachan.[413] According to Tezozomoc, the stations are as follows: Aztlan, Culhuacan, Jalisco, Mechoacan, Malinalco (Lake Patzcuaro), Ocopipilla, Acahualcingo, Coatepec (in Tonalan), Atlitlanquin, or Atitalaquia, Tequisquiac, Atengo, Tzompan, Cuachilgo, Xaltocan, and Lake Chnamitl, Eycoac, Ecatepc, Aculhuacan, Tultepetlac, Huixachtitlan, Tecpayuca (in two Calli), Atepetlac, Coatlayauhcan, Tetepanco, Acolnahuac, Popotla (Tacuba), Chapultepec in two Tochtli.[414] Clavigero states that they left Aztlan in 1160, crossed the Colorado River, stayed three years in Hucicolhuacan, went east to Chicomoztoc, reached Tula in 1196, and finally Chapultepec in 1245.[415] Acosta, Herrera and Duran state that Nahuatlaca tribes left Aztlan in 820 A. D., and eighty years later reached Mexico; that the Aztecs, however, did not start until 1122 A. D.[416] Duran identifies Aztlan with Teo-Culhuacan, and locates it towards our Mississippi Valley. He in common with other writers identifies Chicomostoc with the seven caves.[417] The Tarascos, though speaking a different language, are said to have separated from the Nahuatlacas at Michoacan. They describe the route to the seven caves as across a sea, which they passed in balsas and the trunks of trees.[418] This statement may be of some value in locating that disputed rendezvous of so many tribes; and certainly is more important than a mass of groundless speculation. The next source of interest in this connection is the much perverted and sadly misunderstood migration map first published by Gemelli Carreri, in Churchill’s collection of voyages (vol. iv). Humboldt has given an interpretation which, with the exception of that part which connects it with a deluge and Colhuacan, “the Ararat of the Mexicans,” is generally received.[419]
