We proceed now to note geographically some of the principal ruins. In the vicinity of Vera Cruz the pyramid of Papantla is the conspicuous monument,[1004] but there is little else thereabouts needing particular mention. Among the ruins of the central plateau of Mexico, the famous pyramid of Cholula is best known. The time of its construction is a matter about which archæologists are not agreed, though it is perhaps to be connected with the earliest period of the Nahua power. Duran, on the other hand, has told a story of its erection by the giants, overcome by the Nahuas.[1005] Its purpose is equally debatable, whether intended for a memorial, a refuge, a defence, or a spot of worship—very likely the truth may be divided among them all.[1006] It is a similar problem for divided opinion whether it was built by a great display of human energy, in accordance with the tradition that the bricks which composed its surface were passed from hand to hand by a line of men, extending to the spot where they were made leagues away, or constructed by a slower process of accretion, spread over successive generations, which might not have required any marvellous array of workmen.[1007] The fierce conflict which—as some hold—Cortés had with the natives around the mound and on its slopes settled its fate; and the demolition begun thereupon, and continued by the furious desolaters of the Church, has been aided by the erosions of time and the hand of progress, till the great monument has become a ragged and corroded hill, which might to the casual observer stand for the natural base, given by the Creator, to the modern chapel that now crowns its summit; but if Bandelier’s view (p. 249) is correct, that none of the conquerors mention it, then the conflict which is recorded took place, not here, but on the vanished mound of Quetzalcoatl, which in Bandelier’s opinion was a different structure from this more famous mound, while other writers pronounce it the shrine itself of Quetzalcoatl.[1008] [Illustration: MEXICAN CALENDAR STONE.
