52 A STUDY OF THE MANUSCRIPT TROANO. 



have adopted, which is repeated on the annexed Table XXI, does not 

 preclude us from accepting Perez's theory that they were numbered from 

 the second day of the first year, which, as the periods begin with Cauac, 

 would be Ahau. This would change the position of the Ahaues so far as 

 their numbers are concerned, and they would then stand as shown in this 

 table; that is, the first one in the grand cycle would be No. II, the next 

 XIII, and so on in the usual order. But one very serious objection to this 

 plan of numbering is that 4 Kan of the Xlllth Ahau would be the sixth 

 instead of the eighteenth year. 



I am of the opinion that the only foundation Perez had for thus num- 

 bering these periods is the fact that the name "Ahau" was applied to them. 

 It is probable that it was sometimes so applied on account of their impor- 

 tance, but a careful study of the language of Landa and Cogulludo lead 

 me to believe that Katun was the name by which they were usuall}^ desig- 

 nated. The latter author gives this term only. Landa simply remarks that 

 "they counted 13 twenties with one of the twenty letters of their month 

 which is called Ahau, without order and alternate only as on the border of 

 the wheel above; they called these, in their language, Katunesr^ 



The most serious objection which, so far as I see, can be urged against 

 my theory is that the series of Ahaues does not begin Avith XIII, or, in 

 other words, that the first of the grand cycle is not XIII. But this objec- 

 tion applies with equal force to Perez's scheme. If we adopt the division 

 shown in Table XVIII, and suppose the numbering to correspond with the 

 first year (Cauac) of each period, we would then commence the grand 

 cycle with the Xlllth Ahau. To illustrate this I give a table (XXII) sim- 

 ilar to XVIII so far as the division of the grand cycle is concerned, but 

 numbered as above suggested.

 tenian cierto mode de contar los tiempoa y siis cosas por edades, las qualcs hazian do veynte en veynte 

 anos, contando XIII veyntes con una do las XX letras do los mescs que llaman Ahau, siu ordeu siuo 

 retruecanados como pareceran en la siguiente ray a redouda; llaman les a estos en su lengua Eatunei, 

 y con ellos tenian a maravilla cuenta con sus edades, y la fue assi facil al viejo do quieu en el priiuero
