BORSTEMANN] TEMPLE OF INSCRIPTIONS AT PALENQUE 579 



Thirdly and lastly, 



R 11: V 15; 0, 14 (1 Ix). 



S 11 R 12: 2+11x20-1-9X360=3,482=13X260+82== 10X365— 188. 



T 1: IX 17; 18, 4 (11 Kan). 



But V 15 to IX 17=82 and 6, 14 to 18, 4=— 188. 



I now come to a mysterious circumstance. It is this, that though 

 (he period corresponds to the time between the two neighboring dates, 

 it only does so when the j)rocess is reversed and the computation is 

 made from the second to the first : 



C 11 D 11 : X 17; 13. 7 (0 Muluf). 



E 1 F 1: 9 X 20+ 12 X 360=4,-500= 17X260+80= 12X365+ 120. 



E 3 F 3: VIII 17: 13, 1 (10 Muliic). 



But VIII 17 to X 17=80; 13, 1 to 13, 7=120. 



I would also note that the 9 in E 1 is only a conjecture with me; 

 the original being plainly 8. 

 Similarly, 



E 6 F 6 : V 5 ; 1, 8 (9 Mnlnc). 



E 7 P 7: 8+4X20+2x360=808=3X260+28=2x365+78. 



E8F8: III 17; 3, 4 (7 Cauac). 



But actually, III 17 to V 5=28: 3, 4 to 1, 8=78. 



Thirdly and lastly, 



P 7: VII 3; 19, 12 (4 Muluc). 



Q 7 to 8: 9X144.000+7X7.200+11X360+3X20=1,3,50,420=5,193X260 



+240=3,699 X 365+285. 

 P 10 Q 10 : I 3 ; 19, 16 (9 Mulue). 

 And. in fact, I 3 to VII 3=240 ; 19, 16 to 19, 12=285. 



There seems also to be backward computation in the case of U 5 

 to U 8, but the characters of U 8 have certainly undergone a change 

 which as yet is inexplicable. 



Since this backward computation occurs several times, it can not be 

 based upon a confusion of the two dates or upon a mere accident. 

 Furthermore, I think it also occurs in columns Q and R, of the 

 Temple of the Sun at Palenque (Maudslay, plate i.xxxix). One 

 hardly would think that the Maya priests tried in this way to obscure 

 the meaning of the inscri])tions. 



In two cases the period between the two dates is evidently omitted 

 l)ecause the interval between the dates is the same in the tonalamatl 

 and in the year : 



G 9 H 9 : X 17 : 1.3, 7 (9 Muluc), 

 H 10: V 5; 1. S (9 Mulue). 



For the interval X IT to V 5 and 1:^ 7 to 1, 8 is in each case only 

 8 days: 



P 10 Q 10: I 3: 19. 16 (!) Mulue). 

 SI: VII 3; 14, 10 (10 Ix).
