This assumes that the worship of Kukulcan was never heard of by the Mayas until the Aztecs arrived in Mexico, an assumption for which there is no warrant, and which proceeds in utter disregard of facts. It was the Aztecs who had never heard of Kukulcan, or, at least, had not adopted his worship, previous to this time. The Aztecs, when they settled in Anahuac, did not impart new ideas, religion, or culture to any body; on the contrary, they received much from the civilization of their new neighbors, which was more advanced than their own. It is very certain that neither the Mayas nor the Quichés borrowed any thing from them. We need not go back so far as the ninth century to find the time when the Aztecs adopted, or at least organized in Mexico, the worship of Kukulcan, whose name they transformed into Quetzalcohuatl. His worship did not begin with them; they did not introduce it; they found it in the country as a very ancient worship, and adopted their form of it from the people who yielded to their sway. If M. de Charencey will inquire with a little more care, he will discover that Kukulcan was one of the very oldest personages in Central American mythology, as _Con_ was one of the oldest in that of Peru. Kukulcan, sometimes as Zamnà, was associated with almost every thing in civilization. He introduced the beginnings of civilized life, invented the art of writing, and was to the Central Americans not wholly unlike what Thoth was to the Egyptians, and Tautus, or Taut, to the Phœnicians. If the bas-relief of the cross at Palenque were half as old as his worship in Central America, it would be far more ancient than any one has supposed. GENERAL INDEX.
