perhaps, the most wonderful of all that have been explored hitherto in this lonely region; and, while we regret that our duty to the living present will not permit us to dwell longer on the curious past, we shall, nevertheless pause, occasionally, as we pass through the Mexican States, to notice those remains which have either been visited by us personally, or are not described in books as accessible to all classes of enquirers and students as those of Messrs. Stephens, Catherwood and Norman. Mr. Stephens believes, after full investigation, that these towns and cities were occupied by the original builders and their descendants at the period of the Spanish conquest, and our own opinion entirely coincides with his reasoning and judgment. Those who desire a complete and conclusive illustration of this branch of the subject will find an excellent argument thereon in both of his publications.[1]
In the first volume of this work we have given an account of the Mexican or Aztec Calendar; and the proximate identity of the Yucatese or Mayan and Aztec Calendar led Mr. Stephens to the conclusion that both nations had a common origin. This argument is also important in considering the period of the occupation of the Chiapan and Yucatese edifices, inasmuch as we know that the Aztecs of Montezuma's period used the Calendar which we have already illustrated and described.
Yucatan Calendar.
"Our knowledge of the Yucatan Calendar," says Mr. Gallatin,[2] "is derived exclusively from the communications made by Don J. P. Perez to Mr. John L. Stephens, and inserted in the appendix to the first volume of this gentleman's Travels in Yucatan. It is substantially the same with that of the Mexicans, though differing in some important particulars.
"The inhabitants of Yucatan had, like the Mexicans, the two distinct modes of computing time, by months of twenty days, and by periods of thirteen days. They also distinguished the days of the year by a combination of those two series, precisely similar to that of the Mexicans. And their year likewise consisted of 365 days, viz., of eighteen months of twenty days each, to which they added five supplementary days; and also of a corresponding series of twenty-eight periods of thirteen days each, and one day over.
