INSCRIPTIONS OF THE EARLY PERIOD. 99 
Following after seven intermediate glyphs, there is recorded in p13-c15 
a distance number of 1.18.3.12.0, and after five more glyphs the date 9 Ik 
15 Ceh at £1, Fi. 
If 1.18.3.12.0 be counted forward from 13 Ik o Chen, the terminal date 
reached in the first calculation, the date reached will be 9 Ik 15 Ceh, which 
is recorded in £1, F1._ It therefore seems certain 
that with the possible exception of the month- 
sign of the second date, 7. ¢., ? Mol in pg, this 
text is correct, the calculations agreeing with the 
glyphs recorded. 
Let us next examine ps9. Since the day-sign 
in c9 is very clearly Ik, the month coefficient in 
p9a must be either 0, 5, 10, or 15, which reduces 
the possible meaning of 9a to one of these four 
numerals. Now, although the month-sign re- 
corded is Mol, and the month-sign as indicated 
by the calculations should be Chen, the month 
coefficient itself can only be o. For if 1.9.2 is 
counted forward from 4 Ahau 8 Cumhu or 
1.18.3.12.0 is counted backward from g Ik 15 
Ceh, the date reached in either case will be 9 Ik 
o Chen. It therefore seems certain that poa is 
to be identified as 0, the month to which it is 
attached being incorrectly given as Mol instead 
of Chen. Mol was the month immediately pre- 
ceding Chen, and this may have given rise to the 
error in the month-sign here. 
But the resemblance between p9a and the 
tun coefficient of Stela 18 in Ada, figure 15, has 
already been pointed out, and on the basis of this 
close similarity we are probably justified in iden- 
tifying Ada as a sign for o. 
This identification, moreover, does not rest 
on this one apparently corroboratory passage 
alone. In figure 17, a, is shown a Calendar Round 
date from one of the piers in the western court 
of the PalaceGroupat Palenque.’ Thisis clearly

Now, Manik can have only four possible month ™ aoa 
coefficients, 0, 5,10, and 15. ‘Therefore, because of this fact, and because of 
the resemblance just noted, it seems reasonably safe to conclude that the
