238 MAYAN CALENDAR SYSTEMS [eth. ann. 22 



12 Kayab is the initial day of a great cycle and that 20 cycles are 

 counted to the great cycle, since the number 11,520,000 is obtained 

 as follows : 



1 cycle 144.000 days 



Multiplied by... 30 



1 great cycle 3, 880, 000 days 



Miiltiplied by 4 



4 great cycles 11, 520, 000 days 



If we follow Goodman's method and count onty 13 cycles to each 

 great cycle, 4 of the latter, together with the minor jieriods of the 

 series as given above, will amount to 8,432,942 days. Subti'act 444 

 calendar rounds, and there remain 5,822 days, which, counted from 9 

 Kan 12 Kayab, bring us to 7 Cimi 14 Pax. This is not cori-ect as to 

 the number of the day or as to the month. The same daj^ should 

 be reached, for the number of cycles is the only thing in the series 

 changed. 



We take ne.Kt the black series of the same pair, to wit, 4-0-7-12-4- 

 10, 3 Ix 7 Pax. This changed into d-^ys is as follows: 



Days 



4 great cycles (of 20 cycles each) 11,520,000 



6cycles 864,000 



7 katuns 50, 400 



ISahaus 4,320 



4 chnens 80 



10 davs 10 



Total 12.438.810 



Subtract 655 calendar rounds 12. 431 . 900 



Remainder . 6,910 



Using this remainder and counting forward from 9 Kan 12 Kayab, 

 j^ear 3 Ben, the same initial date as before used, we reach 3 Ix 7 Pax, 

 year 9 Lamat. This is correct. 



The series in the folds of the right serpent (same plate as the pre- 

 ceding) are as follows: 



Black 4-6-9-1.5-12-19. 13 Akbal 1 Kankin 



Red 4-6-1-9-1.5-0, 3 Kan 16 (?) Uo 



Changing the red series into days, we have the following result:
