INSCRIPTIONS OF THE GREAT PERIOD. 305 
the 13 tuns may have in 02, the date in 01, P1 is almost surely 9.15.0.0.0 
4 Ahau 13 Yax. 
The last date, 03, p3, is either 2 Eb 0 Pop or 3 Eb o Pop, in either case 
another Maya New Years’ day. The lower dot is surely numerical, which 
makes the number either 2 or 3; and as the stump of the middle dot is larger 
than the bottom one, this number is probably 2. The writer examined this 
coefficient very carefully in 1916 and came to the conclusion that it could 
only have been 2. Indeed, if the day coefficient is 2, such an interesting 
relationship with the first date on this altar develops that we would be almost 
justified in so reading it, even if 2 were not the best value obtained by in- 
spection. Ifthis date is 2 Eb o Pop, when used with the first date in this text, 
3 Caban o Pop, two consecutive New Years’ days are recorded; and since 
the Initial Series of 3 Caban o Pop has been assumed tohave beeng.15.9.10.17, 
that of 2 Eb o Pop can be reached by calculation as follows: 
g.15.9.10.17 3 Cabano Pop 
I. O. 5 =I year of 365 days, backward 
(al nko 2 ee 2 OP op 
This coincidence is so striking as to make it practically certain that both 
dates are correctly deciphered as given. 
From this point on to the end of the inscription in vi there are no other 
glyphs of a calendary nature, so far as known. 
Before analyzing the possible significance ofthis text, let us summarize 
the dates deciphered, arranging them so far as possible in their chronological 
order:

The first outstanding fact in connection with this inscription is that the 
closing and probably also the contemporaneous date as well, is the important 
date 9.16.12.5.17 6 Caban 10 Mol, recorded most conspicuously as the first 
date on the back.
