This date appears, therefore, to have been very correct. _Of the Origin of this Cycle._ The origin and use of this species of age, epoch, or cycle, and (the time) when it commenced, are not known. Neither the Mexican nor Toltecan authors, nor those who corrected the chronological system for the computation of time, ever used it, nor had their writers any knowledge of its existence. The few and incomplete manuscripts which exist in this peninsula make no mention of it; so that there is neither record nor even conjecture to guide us, unless there be something on the subject in the work written by Don Cristobal Antonio Xiu, son of the King of Mani, by order of the then government, which, according to the padre Cogolludo, existed in his time, and some allege to be even yet extant.
