Reading edition
It is curious that these latter resemblances (as far as I have been able to investigate the subject) disappear in the signs of the Yucatan calendar, though its arrangement is precisely that of the Mexican. Any one interested in the theory of the Toltecs being the builders of Palenque and Copan will see the importance of this point. If the Toltecs ever took the original calendar, with the traces of its Asiatic origin fresh upon it, down into Yucatan with them, it is at any rate not to be found there now.
