thomIs] series in plate XXX, DRESDEN CODEX. 51 



to complete the cycle to 11 Aliau — which appears to be the i)lan of these 

 series — the total is 2,340 days, or 9 cycles of 2G0 days each, or, in other 

 words, nine sacred years. 



Turning" now to table 3 (page 21), and selecting 11 Ahau in either col- 

 umn and counting forward continuously, using the same day column 

 without adding the five days, it will be seen that the proper days will 

 be reached.* For example, Ahau, the third day in the Ezanab column, 

 may be selected, and the count may be carried from 11 opposite in the 

 fourth number column. Continuing from this 117 days, 11 Caban, the 

 twentieth day of the ninth number column is reached ; 117 days from 

 this (going back to the first column v/hen the thirteenth is completed) 

 ends with 11 ]x, the seventeenth day of the second number column ; 117 

 more with 11 Chuen, the fourteenth day of the eighth number column; 

 117 more with 11 Lamat, the eleventh day of the first column ; and so on 

 to the end. It is evident, therefore, that the series can be traced in 

 years of 360 days, if these years begin with the same day. 



An attempt will now be made to trace it in accordance with the 

 usual calendar system. However, as it appears to be usual in this 

 codex to begin the years and months with the days usually considered 

 the last, as has been found true of the series 07J plates 40-50, it may be 

 taken for granted that the same rule holds good here. If the reader 

 has learned how to count by the comiionnd calendar, table 3, it may be 

 used in following the exj^lanation. As there is nothing whatever in 

 the series to indicate the years to which it is applied, it must be 

 considered of general application, and may begin in any year. The 

 year 1 Akbal, in which 11 Ahau falls on the eighteenth day of the 

 thirteenth month, Mac, may therefore be selected. Carrying the count 

 forward from this date 117 days, or five months and seventeen days, 

 the next year, M'hich should be 2 Lamat, is entered. Counting now five 

 months and two days (or 102 days), 9 Ik, the last day of the year proper, 

 is reached, and five days more end with 1 Manik, the last of the added 

 days; 2 Lamat will therefore be the first day of the next year. As 107 

 days have now been counted, the further count of 10 days, commencing 

 with 2 Lamat, extends to 11 Caban, the second day in the left-hand 

 column of our series. This is the tenth day of the first month, Pop, of 

 the year 2 Lamat. Counting forward from this, 117 days reaches 11 

 Ix, the seventh day of the seventh month, Yaxkin. As this is the 

 third day in the series, the count is carried forward 117 days more and 

 reaches 11 Chuen, the fourth day of the thirteenth month, Mac; and 117 

 days more reaches 11 Lanuit, the last day of the (;olunin. This is found 

 to be the first of the supplemental days of the year 2 Lamat. In taking 

 the next step, four days are counted in this yeai' and 113 days in the 

 year 3 Ben. This period of 1 17 days closes with IL Chicchan, the first 

 day of the second column of the series given above.
