same as that found in glyph F9, which he interprets 20. His descrip 
tion of the series is as follows: 
Then [after 4 Ahau 8 Cumhu] follows another reckoning of 1-92 [1 ahau, 9 
chuens, 2 days], succeeded by five unintelligible glyphs, to 13 Ik, 5 Mol. The com- 
putation and the 13 Ik are right, but the month should be 20 Chen, as will be seen by 
reference to the annual calendar. It will be evident pretty soon that the sculptors 
got their copy mixed up. The 5 Mol should have gone with another date (p. 135). 
The intermediate time periods are 1 ahau (of the usual form, a, 
figure 9), 9 chuens, and 2 days:

As the first date is uncertain, unless the explanation given above be 
accepted, we must count back from 13 Ik 20 Mol, which falls in 
the year 10 Akbal. I use 20 Mol, as I believe 20 to be the true 
interpretation of the unusual number symbol, and it is really that 
adopted by Mr Goodman in his calculation, though not expressed. 
As 20 Mol is the one hundred and sixtieth day of the year, and the 
count is backward, we subtract this from 542, and divide the remainder 
by 365, which gives 1 year and 17 days; this brings us to the year 8 
Ben. Deducting 5 for the intercalated or added days, and counting 
back 12 days from the end of the month Cumhu, we reach 4 Ahau, the 
eighth day of the month Cumhu, proving that this terminal date of 
the preceding series is correct and that the error of that series must 
be in the initial date or in the numerals attached to the intermediate 
time periods. This result is in fact the same as that obtained by 
Mr Goodman, who commences his count of the days of the month 
with 20, transferring the last days of the columns in our table 1 to 
the first place, as is shown in table 4, given below, which is simply 
a condensation of his ‘*‘ Archaic annual calendar,” where each of the 
fifty-two years is written out in full.
