206 THE INSCRIPTIONS AT COPAN. 
kin-sign and coefficient and a4 1. h. the day-sign and coefficient; and finally, 
AS, the first two glyphs of the Supplementary Series. 
The next two glyph-blocks, a6 and a7, show the closing glyphs of 
the Supplementary Series, the last, Glyph A, appearing in a7 1. h. as u. h. 
is the month of the Initial Series terminal date, and is very clearly 18 Kayab. 
The writer gave these pieces of Stela 5 a very close study in 1912 and again 
in 1915 and 1916, and feels certain of the above identifications. This Initial 
Series therefore may be deciphered as follows: 
AI Initial Series introducing glyph 
Azu.h. 9g cycles 
A2\.h. 13 katuns 
A3u.h. over 10 tuns and best as 14 
A3 1. h. ? uinals (missing) 
Agu.h. 0, 5, 10 or 15! kins (missing) 
Aaloh; ? ? (missing) 
Agsu.h. 18 Kayab 
The next step in deciphering this date is to ascertain the places in the 
second half (7. ¢., after Tun 10) of Katun 13 of Cycle 9, where 18 Kayab, 
the month of the Initial Series terminal date, could have occurred. These 
will be found to have been as follows: 
(1),6.1 3h 1-00 3 Ahau 18 Kayab 
(2) O:17-12.0-06 4 Chicchan 18 Kayab 
(3) 9.13.13.0.10 5 Oc 18 Kayab 
(4) 9.13.14.0.15 6 Men 18 Kayab 
(S¥ 9.14, 15.i.°0 7 Ahau 18 Kayab 
(6) 9.13.16.1. 5 8 Chicchan 18 Kayab 
(7) 0.8328 7.1.50 g Oc 18 Kayab 
(8) 9.13.18.1.15 10 Men 18 Kayab 
(9) 9.13.19.2. 0 11 Ahau 18 Kayab 
It is certain that the Initial Series on Stela 5 is one of the foregoing, 
although, because of the loss of a3 1. h., and a4, and the failure to identify 
A3a u. h. exactly, it is impossible by a mere inspection of the text to decide 
which. Arguing from antecedent probability, the kins would be more likely 
to be o than 5, 10, or 15, which would give the day-sign Ahau, instead of 
Chicchan, Oc, or Men. If this assumption is correct, all but the first, fifth, 
and ninth of the above readings would be eliminated, and of these, since it 
is a tun-ending, the first is the more likely to be correct. It seems unsafe, 
however, to make this perfectly legitimate assumption here, because of the 
nature of the first two glyph-blocks on the opposite side of the monument, 
namely, B1 and B2, which clearly record a Secondary Series composed of 15 
kins (B1b), and possibly some uinals (B2a). The kins of this number are 
perfectly clear in Bib, and it is barely possible that B2a may record some 
number of uinals. 
Leaving this Secondary Series number indeterminate for the present, 
let us continue the inspection of our text. Passing over the next two glyph- 

1 Since the month coefficient in the Initial Series terminal date is 18, the kin coefiicient must have been one of 
these four numbers, corresponding with the days Ahau, Chicchan, Oc, and Men respectively. This latter is true 
because only these four days can have a corresponding month coefficient of 18.
