forstbmann] the numbers 435 



numbers, 9,100, really has anything remarkable about it, as it is 

 divisible not only b}' the tonalamatl, but also by the year of 13 

 months, which has 3()4 days. These figures were for a long time a 

 puzzle to me, since they do not form a series and have n(> legitimate 

 relation to their neighbors. They produce somewhat the effect of a 

 mere aid to computation, such as one jots down on a separate sheet in 

 the course of some great mathematic task. 



A light suddenly dawned upon me when T combined the first and 

 third and second and fourth numbers by addition or subtraction. T 

 thus obtained four results : 



1. 185,120+33,280=218,400, which is just 000 13-month years of 

 364 days, 280 Mars years of 780 days, 840 tonalamatls, and 7,800 

 months of 28 da3's. 



2. 185,120—33,280=151,840; that is, the largest number in the 

 topmost line, as well as 416 solar years of 365 days, 52 periods of 2,920 

 days, and 260 Venus years of 584 days, oi- the product of the days 

 of the tonalamatl and of the Venus year. 



3. 68,900+9,100=78,000; that is, 100 Mars years or 300 tonala- 

 matls. 



4. 68,900—9,100=59,800; that is, 520 Mercury years of 115 days 

 or 230 tonalamatls or five times the notable period of 11,960 days 

 already mentioned. This can not be chance. The facts speak too 

 plainly. But w^ho can penetrate the intellectual workshop of the 

 Indian author and trace his course of thought and mode of work? 



The four columns at the right of the page having been thus dis- 

 posed of, let us turn to the three on the left, and first to that part of 

 them which is below the forty hieroglyphs. 



I Avill here repeat this j^assage from the transcript of page 24

We will first dispose of the number 2,200. It is simply the differ- 

 ence between the two large numbers and, as is usual with differences, 

 is provided with a red circle surrounding its lower figure (0). 



Three calendric dates and two numbers now remain. The number 

 belonging to the date on the right is missing, probably only for Avant 

 of space, as often happens in this manuscript. I will supply it in 

 parenthesis and write each date, adding the year of each, below the 

 number belonging to it. We then have as follow : 



1.366,560 1.364.360 (1,352,400)
