MAYAN CALENDAR SYSTEMS 



[ETH. ANN. 22 



ooiiiinon calendar." On what he bases this opinion, which is equiva- 

 lent to saying they had ditfeient numeral systems, I am not aware. 

 That the system in vogue at Tikal (in the Itza region of the Peten 

 district) was the same as that of the insci-iptions at Palenque, Copan, 

 and Qnirigna is well known. 



Let us return to the exceptional series of the Copan insci-iptions 

 mentioned above (west side of Stela N). Although 

 it was discussed at some length in my previous 

 paper, a reexamination has brought to light some 

 facts overlooked in the first examination, which 

 have an important bearing on the question in- 

 volved; and the}' will be noticed here. This series 

 reversed is as follows: 14-1 7-1 0-1 d-O-O to 1 Ahan 8 

 Chen (figure 158). Written out it is 14 great 

 cycles, 17 cycles, Ifl katuns, 10 ahaus, chueus, 

 days, to 1 ^Vhau 8 Chen. Changed into days it 

 gives the following result, counting "20 cycles to 

 the great cycle : 



Days 



14 great cycles. 40. 320, 000 



17 cycles 2,448,000 



19 katuns 136.800 



10 ahaiis. 3,600 



>• Total 42,908,400 



Suhtract 2,260 calendar roiinds 42, 894, 800 



Remainder 



13, 600 



If we count back this number of days from 1 

 Ahau 8 Chen, year 3 Ben, it brings ns to 1- Ahau 

 13 Zotz, j'ear 5 Lamat, which will be the first day 

 of the first, or most remote, of the 14 great cj'cles, 

 connting the series in this manner upward from 

 the loth: 



1st great cycle 



2nd great cycle, etc.. to 



14th great cycle 



(loth great cycle) 



17 cycles 



19 katuns 



10 ahaiis 



chuens 



days 



If we count back from the same date (1 Ahau 8 Chen) the 17 cycles, 

 r.i katuns, and 10 ahaus, we reach the first day of the (incomplete) 

 loth great cycle as we have numbered them above. This day is 5
