INSCRIPTIONS OF THE MIDDLE PERIOD. 215 
Assuming that altars as well as stele were used for hotun-markers, we 
have the following hotun-endings marked in the Middle Period: 
Stela 12 and 2 (doubtful) g.10.15.0.0 6 Ahau 13 Mac 
stele 12, 2,,10, 19, 23, 13, and 39.11. 0.0.0) 12 Ahau 8-Ceh 
Stela 1 and the East Altar of Stela 5 9.11.15.0.0 4 Ahau 13 Mol

Stela 5 §.13,15:0.0 13 Ahau 18 Pax, or 
9.14. 0.0.0 6 Ahau 13 Muan 
It is apparent from the foregoing that while every katun-ending in the 
Middle Period is represented by one or more monuments, only two of the 
five lahuntun-endings and only two or possibly three of the ten first and third 
hotun-endings are represented by monuments. In other words, it would ap- 
pear as though efforts were not made to erect monuments on every first and 
third hotun in the Middle Period or even on every second hotun, namely, 
every lahuntun, but only on every fourth hotun, namely, every katun. 
These gaps in the sequence of the monuments during the Middle Period 
are shown in the following table:

It is very doubtful whether any of the three hotuns in Group A, with the 
possible exception of 9.10.10.0.0, were ever marked by the erection either of 
stele or altars. At the conclusion of this katun in 9.11.0.0.0 no less than 7 
stele were set up, and the energy going into the making of these, as well as 
into the construction of other buildings then in course of erection, may 
explain the observed hiatus at this point in the sequence of the monuments. 
Why the two hotuns in the next group, B, and particularly the second, 
g.11.10.0.0, should not have been marked is unknown, though here again the 
next hotun, 9.11.15.0.0, was signalized by the erection of two monuments, 
a stela and an altar. 
After 9.12.5.0.0 (Stela I) there are no first or third hotuns marked in the 
Middle Period, which probably satisfactorily accounts for the breaks in the 

1 This date is recorded as the Initial Series on Stele 12 and 2, it will be remembered, but probably not as 
their contemporaneous dates. 
2 This date occurs as a period-ending on Stela F, a monument of the Great Period, but not as its contempo- 
raneous date. 
3 This date occurs as a period-ending on Stela 4, a monument of the Great Period, and also as a period-ending 
on the Hieroglyphic Stairway of Mound 26 (Date 22), but in neither case is it the contemporaneous date of these 
monuments.
