THE HOTUN. 575 
Ahau, and this monument is one of those very ‘“‘stones”” which Landa says the 
natives told him they were accustomed to erect ‘‘every 20 years, which is the num- 
ber they use for counting their ages.’”’ Referring to the u kahlay katunob on page 
503, we will find that there are only two Katuns 10 Ahau to which this monument 
could possibly have belonged, namely, 11.11.0.0.0 10 Ahau 3 Mac (1182) and 
12.4.0.0.0 10 Ahau 18 Uo (1438). The writer inclines to the latter of these, as the 
carving on Stela g is excellently preserved, and the more recent date is therefore 
the better of the two. 



Fic. 90.—a. Principal part of design on front of Stelag at Mayapan, Yucatan. b. Part of 
middle section of page 11 of the Codex Peresianus. 
If 12.4.0.0.0 10 Ahau 18 Uo was the Initial Series corresponding to this Katun 
1o Ahau, as the writer believes, then Stela 9 was the last monument to be erected 
at Mayapan, because before the next one fell due, 7. ¢., at the end of the next katun, 
Katun 8 Ahau (1458), the city was destroyed by a league of Maya chieftains under 
the leadership of Tutul Xiu, halach vinic of Uxmal, and the Cocom forced to seek 
new homes elsewhere. 
Coming next to the codices, the writer has stated in Chapter I (see page 43) 
that the middle sections of pages 2 to 11 of the Codex Peresianus appear to record 
an u kahlay katunob. Here we can see a series of 10 pictures, each having two 
anthropomorphic figures facing each other, just as in figure 89, and more particu- 
larly in figure 90, a, and similarly between the two figures in each picture there is a 
day Ahau, decreasing from left to right by 2 in each picture, beginning with 2 Ahau 
on page 2 and continuing as follows: 13 Ahau (p. 3), 11 Ahau (p. 4), 9 Ahau (p. 5), 
7 Ahau (p. 6), 5 Ahau (p. 7), 3 Ahau (p. 8), 1 Ahau (p. 9), 12 Ahau (p. 10), and 10 
Ahau (p. 11), possibly parts of an u kahlay katunob. 
The picture on page 11 of this codex is shown in figure go, b, where we see two 
anthropomorphic figures facing each other. Here the left-hand one is Itzamna, 
God D; the right-hand and smaller one, sitting on a platform, is badly effaced. 
Itzamna offers in his hand the head of Kukulcan, the Long-nose God (B of the 
Schellhas classification), and just in front of this head 1s again the day 1o Ahau. 
The writer believes this picture shows the same Katun Io Ahau as the one on 
Stela 9 at Mayapan, and it should be noted that the same deity, God D, is the 
principal figure in each tableau. If this identification 1s correct, pages 2 to 11 of the
