INSCRIPTIONS OF THE GREAT PERIOD. 223 
Attention should be called to the peculiar form of the last glyph of the 
Supplementary Series in this text at asa: @=ss _This sign has the coefficient 
g, one of the only two possible (9 or 10), and stands in the regular 
position, 7. ¢., immediately preceding the month-sign. ‘The main part 
of the glyph, however, is entirely different from the usual forms. (See 
Morley, 1916, plates 1-10, Glyph A.) So far as the writer knows, this 
variant occurs as the last glyph of the Supplementary Series in but two 
other places, on Stela N, also here at Copan, and on Slab 6 of the Hieroglyphic 
Stairway at Naranjo. On Stela N the coefficient is 10 instead of 9.1. This same 
variant but with another superfix appears again on Stela A at cob. The reason 
for its use in these three texts and in no other is unknown, but that it is the 
same as the usual form seems probable from the fact that: 
(1) This variant in all three cases is the last glyph of the Supplementary 
Series, and in two immediately precedes the month-sign; and 
(2) In all three cases it has the coefficient 9 or 10, the only ones possible 
with the last glyph of the Supplementary Series. 
A summary of the chronological parts of this text follows:

The possible significance of the second date above has already been 
explained. The next to last date, 9.15.0.0.0, is the katun-ending this monu- 
ment was erected to commemorate. 
Stela A is the most elaborate monument yet encountered. The carving 
of the glyphs is well-rounded, giving a finish and softness of outline to the 
glyph-blocks not encountered in any of the earlier sculptures. There are 
13 +26+13 =52 glyph-blocks in the entire text. 
According to Spinden, there are a few traces of a monolithic altar of 
undetermined character in front of this monument.’
