THOMAS] SECONDARY SERIES OF QUIRIGUA INSCRIPTIONS 233 



9th cycle, but the symbol 6 Aliau (glyph KJ) denotes, if we have cor- 

 rectlj' intei'iireted it, that <i Ahaii 13 Kayab is the first daj' of the Gth 

 ahau; nevertheless, Goodman's method of counting gives the correct 

 result. Attention will again be called to the subject further on. 



Returning to our inscription, we find in the 20tli glyph the brief 

 series 19 ahaus followed by the date Ahau 13 Chen or 13 Zac, but 

 the series does not connect the dates. There are no other recogniza- 

 ble series in the inscription. 



The inscription on the west side of Stela C — the drawing of which 

 is shown in Maudslay's plate 19, part 11 (our figure 147) — has, as 

 heretofore stated, the initial series 5J:-9-l-0-0-0, 6 Ahau 13 Yaxkin. 

 Following this date, at glyph.s 16 and 17, is the numeral series 17-5-0-0, 

 that is, 17 katuns, 5 ahaus, chuens, days, though in the itsual 

 i-everse order of days, chuens, ahaus, katuns. This is in turn fol- 

 lowed by the date Ahau 13 Kaj'ab. If we count this series as 16 

 katuns and 5 ahaus, it will exactly express the lapse of time from 6 

 Ahau 13 Yaxkin, the preceding date, to Ahau 13 Kayab, the date 

 which follows. But turning to Goodman's "Ai'chaic Chronological 

 Calendar," 54th great cycle, we find that the latter date, accoi-ding to 

 his numbering, is the 5th ahau of the 17th katun of the 9th cj'cle. 

 Shall we accept this as the proper reading, or shall we conclude that 

 there is an error in the number of katuns? 6 Ahau 13 Yaxkin is 

 the first day of the 1st katun of the 9th cycle, according to Goodman's 

 method of counting (though the 2nd, in fact, if the count began with 

 1), and 6 Ahau 13 Kayab is the first day of the 5th ahau, as Goodman 

 counts (Gth in fact), of the 17th (IStli) katun. Counting from one 

 date to the other gives just 16 katuns 5 ahaus, as the following sub- 

 traction shows: 



9-ir-.5-0-0 

 9- 1-0-0-0 



16-5-0-0 



It is pi'oper to bear in mind that by Goodman's method of number- 

 ing, the number given always expresses the number completed ; thus, 

 as he begins with 13 in numbering the cycles, his 1st cycle is in reality 

 the second, one cycle having been completed and the 2nd entered 

 upon. I am therefore disposed to correct 17 katuns in the series just 

 examined to 16. 



As these are the only series of the Quirigua inscriptions to which it 

 is desirable to call attention at iiresent, the next subject of examina- 

 tion is the great-cycle symbols, but in oi'der to enter upon this intelli- 

 gently it is necessary to discuss some points of Goodman's sj-stem not 

 fully examined in mj' previous paper. In doing this it will be neces- 

 sary to go to the very base of his system.
