36 A STUDY OF THE MANUSCRIPT TROANO. 



with a Cauac year. On each, the divisions between the Ahaues are marked 

 by solid, heavy, black lines; the usually counted twenty years of each are 

 surrounded by a single dotted line, and the period covered by the four 

 plates by a continuous waved line. The point at which the grand cycle 



begins is marked thus: :o: . If we examine Table XIV we see that 



1 Cauac is the first year of a cycle, and 1 Muluc the first of the usually 

 "counted years" of an Ahau, and that both are within the period covered 

 by the four plates; each is surrounded by a ring in order to designate it. 

 As a matter of course, each is the first year of an "Indication" or week of 

 yeai's; so are 1 Kan and 1 Ix in the same period, yet neither of these is 

 thus distinguished. 



If we turn now to Table XV, in which the cycle begins with a Kan 

 year, we can see no reason why either the 1 Cauac or the 1 Muluc in the 

 period embraced by the waved line should have any special mark of dis- 

 tinction. 



It is proper to state here that unit numerals surrounded in a similar 

 manner by a circle of dots, are to be found on other plates where it is diffi- 

 cult to fipply the theory here advanced. 



Another difficulty which arises, if we adopt Perez's theory, is that the 

 last Ahau of a grand cycle does not close with the end of that period, but 

 includes one or more years of the following, according to the place the 

 division begins. 



Taking all these facts into consideration, it appears that the calendar 

 system followed by the author of the Troano Manuscript commenced the 

 cycles and the Ahaues with a Cauac year. I think, therefore, the evidence 

 that the Ahaues at least began with a Cauac year is too strong to leave any 

 doubt on this point. 



As bearing upon, and, as I believe, tending strongly to confirm this 

 conclusion, I will introduce here some examples from the Manuscript. 



In the second division of Plates XXX and XXXI, commencing on the 

 left half of the former and continuing through the latter, we observe a series 

 of figures all similar to each other, except the one to the right on Plate 

 XXX, which is the long-nosed god. 



Over each figure, except one, there is a red numeral, but these differ
