THOMA8] NUMBER OF CYCLES IN GREAT CYCLE 243 



of Cfilculating the differences l>et\veeii the series and ijassing- from 

 one of the final dates to the otlier. I liad tried this before, bnt, not 

 allowinji for tlie /Agzug course of the series, I failed to get the dates at 

 the liottoiu ill right relation to the series. 



Taki' first the series in the riirht-hand serpent, as follows: 



Black. 4-6-9-15-12-19, 13 Akbal 1 Kankin 



Red 4-6-1-9-15-0. 3 Kan 16 (IT) Uo 



Difference 8-5-15-1 9 



This differeiiee, eonnted forward from 3 Kan 17 Uo (tlie 1(1 being an 

 error), should reacli i;i Akbal 1 Kaiikiii. 



Reducing to days, we have the following result: 



Days 



Skatuns 57,600 



5 ahaiis _ 1, 800 



15 chiiens _ 300 



19(lays i . 19 



Total __ 59.719 



Subtract 3 calendar rounds ^ 56,940 



Remainder _ 0, 779 



Using this remainder and counting forward from '■) Kan 17 Uo, year 

 G Lamat, we reacli 13 Akbal 1 Kankin, year 13 Akbal. This is cor- 

 rect, and proves that we should read 17 Uo instead of 16. 



The two series in the other (left-hand) serpent are as follows: 



Red 4-6-11-10-7- 2, 3 Cimi 14 Kayab 



Black 4-6- 7-12-4-10, 3 Ix 7 Pax 



Remainder _ 3-18-2-12 



This remainder, counted forward from 3 Ix 7 Pax, which is the date 

 belonging to the black series, will bring us to 3 Cimi 14 Kayab, which 

 is the date belonging to the red series. 



The relation between the pairs of the two sei'peuts is between the 

 like colors. For example, by using the difference between the red 

 series of the right serpent and that of the left, and counting forward 

 from 3 Kan 17 Uo, we reach 3 Cimi 14 Kayab. By using the differ- 

 ence between the black series, and counting forward from 3 Ix 7 Pax, 

 we reach 13 Akbal 1 Kankin. These i-esults serve to confirm the 

 results of the calculations when the entire series is taken into the 

 count. 



There are five other high series in the Dresden codex, to which I 

 have not as yet alluded — four in the serpent figures on plate LXI, and 

 the red series in the serpent on plate LXix. The reason for x)assing 

 over them temporarily is that some of them require correction, and 

 others present difficuKies to successful calculation and satisfactory 

 interpretation wjiich I have not as yet been able to overcome. As the 

 object in view is to discover the ti'uth and not merely to support a
