816 MAYAN CALENDAR SYSTEMS [ETH. ANN. 19 
Akbal 6 Cumhu; that of the right loop 7 (or 2) ahaus, 14 (or 2) chuens, 
19 days, the day above 3 Chicchan (or 13 Akbal); the date below each, 4 
Ahau8 Cumhu. Counting the series of the left loop backward, we reach 
3 Chicchan 13 Yaxkin. This is correct except as to the month, which 
in the codex is certainly Kankin. The reckoning in case of the mid- 
dle loop reaches 13 Akbal 11 Kayab, whereas the month date in the 
original is 6 Cumhu. The series attached to the right loop has been 
corrected by the insertion of a red 2 between the ahau and chuen 
numerals. The long series above has also been corrected, which indi- 
cates some material error here. However, the series will not connect 
with either of the two days aboye, following or rejecting the correction. 
Attention is called to the fact that the numerals inclosed in the loops 
here in each case exceed 13, the highest day number, as the question 
of the use of the numerals will come up in a series to be noticed. 
The series belonging to the red loop on plate 58 (using the original 
black numerals, there being a correction or different series in red) is 
1ahau, 7 chuens, 11 days; the date below 4 Ahau 8 Cumhu, the nearest 
date of the long series to the right is 13 Mulue —? Zac. The reckon- 
ing backward reaches 13 Mulue 2 Zac. The native correction is a 
red 12 inserted between the ahau and the chuens. This has probably 
been inserted to bring the reckoning to the Mulue of the right column 
above the lower date. The series in the upper division connects with 
13 Oc to the right. That in the middle division of plate 48 connects 
with the 3 Lamat over it. Of the two series in the upper division of 
plate 31, that of the right loop connects with the date above, but that 
of the left does not. The series attached to the red loop on plate 24, 
if we consider the red symbol inside as naught, connects with 1 Ahaw 
18 Kayab at the right. 
The series connected with the thirteeen loops, upper divisions of 

plates 71-73, appears to be the usual form of most other series of 
the codex, but in this case the numbers in the loops do not form part of 
the counters, but denote the day numbers of the days reached, counting 
forward (from left to right) from 9 Ix (plate 71), with an interval of 
2 chuens, 14 days. ‘This series is explained in my Aids to the Study 
of the Maya Codices (Sixth Ann. Rep. Bur. Eth., pp. 337-338). It 
may, however, be called a connecting series, as by the numbers in the 
loops—though they are day numbers and never exceed 13—it is joined 
to the series concluding in the upper division of plate 71. 
It will be observed that in each case except the last the day from which 
the reckoning is made is 4 Ahau, and when the month is given + Ahau 
8 Cumhu. It would seem, therefore, that special importance was, for 
some reason, attached to this date by the people of the country and 
era when the codex was written. This, it must be admitted, bears 
somewhat in favor of Dr Seler’s and Mr Goodman’s idea of the impor- 
tance of Ahau in the Mayan time count.
