room close to the 5), and in addition C 2, an unknown ghq)h, with 

 8 prefixed. I think that nothing is more natural than to regard the 

 obscure character B 16 as the seventeenth month (Kayab) and C 2 

 as a glyph for the tonalamatl. The stonecutter of the Cross 

 inscription, therefore, proceeds from the same two dates from which 

 the writer of the Dresden codex proceeds, and this fact increases the 

 probability, already appearing from other circumstances, that the 

 Dresden codex had its origin not far from Palenque, probably in 

 the district of the Tzentals, who, therefore, should receive closer atten- 

 tion from this time forward. 



In spite of many difficulties the interpretation of a few of these 

 groups can be considered correct, as the specified period agrees with 

 a preceding and following date, inasmuch as it is the interval between 

 them. I here give some examples in which, in order to facilitate the 

 examination, I will state the years found by computation in which 

 the dates are contained. 



The simplest example is the twelfth date, the twelfth period, and 

 the thirteenth date, as follows : 



S 14 T 14: II 14; 10, Gth month. (11 Mulue.) 



S 15: 3+6X20=^123. 



T 17 U 1 : VIII 17 ; 13, 12tli month. (11 Muluc.) 



In fact, day II 14 precedes VIII 17 by 123 days, and day 10, Gth 



month is 123 days before 13, 12th month. The year remains the same. 



I will add that day VIII 17 in the last part of the Dresden codex 



is of special importance (see my second treatise, " Zur EntzifTerung 



der Mayahandschriften ", pages 14 to 17). 



The example directly preceding also corresponds admirablv. It 

 forms the eleventh and twelfth dates and the eleventh intervening- 

 period. 



S 10 T 10: XI i>; <>. (ith month. (11 Kan.) 



S 12 T 12: 9+3x20+13x300=4,749. 



S 14 T 14: II 14; 10, Cth month. (11 Muluc.) 



The space between the two dates is actually 4,749=18X200+69= 

 13X365+4. And 69 is in fact the distance from XI 5 to II 14, 4 the 

 distance from 6, 6th month to 10, 6th month. 



In addition, I would mention the second and third dates and the 

 second period : 



D 3 C 4: IV 17; 8, l8th month. (9 Ix.) 



D 5 C 6: 2+9x30 f 360=542. 



C 9 D 9: XIII 19; 20, 8th month. (11 Kan.) 



It should be noticed here that an affix is attached to the sign for 

 360, C 6, which seems to me to denote the close of this period and to 

 prevent the next sign D 6 from being added to it. Moreover, D 9 

 probably denotes the eighth month; but its prefix, according to my 

 supposition, only denotes the close of the month.
