100 ' THE INSCRIPTIONS AT COPAN. 
month coefficient in figure 17, a, is o, even though calculations to prove it 
are wanting. The most that can be offered in corroboration of this second 
case is that one of the places where 13 Manik o Yaxkin occurred in the 
Long Count was 9.12.11.2.7, and there is another date at Palenque, an Ini- 
tial Series, which records 9.12.6.5.8! 3 Lamat 6 Zac, which is within 5 years 
OG. 2a ae 
A third occurrence of this unusual form for o is shown in figure 17, d,a 
Calendar Round date from Lintel 9 at Yaxchilan.2 This is the date 1 Eb 
? Yaxkin. Now, Eb can only have o, 5, 10, or 15 for its month coefficients, 
and therefore one of these values must be substituted for the month coeff- 
cient in figure 17, 0. But this 
sign is like the other three month 
coefficients just described, and 
we are therefore probably jus- 
tified in identifying it also as o. 
Unfortunately there is again no 
calculation by means of which 
this reading can be verified. 
A fourth possible occurrence 
of this form for o 1s shown in 
figure 17, c, which is the Initial 
Series terminal date on the Ley- 
den Plate.’ This Initial Series Fic. 17.—Parts of inscriptions on: a, pier in western court

o Yaxkin, all of which 1s perfectly 
clear except the month coefficient. While the bar attached to the month- 
sign may be the month coefficient 5 (one of the four values possible here, 
1. €.,0., 5, 10, or 15), the writer prefers to regard the unusual element 
as the month coefficient, as the calculations show that 0 and not 5 is GF) 
required here. If this character is turned on either end, it looks not unlike 



‘Maudslay, 1889-1902, vol. iv, plate 78. This latter date is recorded on a fragment of a sculptured slab, 
possibly a stela, which was found on the slope of the pyramid of the Temple of the Foliated Cross at Palenque. 
Although the Initial Series introducing glyph, the cycle-sign and coefficient, and katun-sign and coefficient are 
missing, the writer was able to decipher this Initial Series as 9.12.6.5.8 3 Lamat 6 Zac, which agrees with the day of 
the terminal date as recorded. There is a Secondary Series of 1.10.1, which is counted backward from the Initial 
Series terminal date to reach the date 1 Manik 10 Pop also recorded. 
The whole inscription seems to have read: 
9.12.6. 5.8 3 Lamat 6 Zac 
T10,1 Backward 
9.12.4.13.7 1 Manik 10 Pop 
This is recorded as follows:

The only irregular feature of this text is the omission of the month of the Initial Series terminal date, i. ¢., 
6 Zac.
