632 The Manuscript Troano. [August, 
the 12th day of the 12th month, but in this case we have to count 
the columns from the one having 11 at top (always inclusive) to 
the right through to the thirteenth (the one with 7 at top), and 
then go back to the first and count up to the one in which we find 
8 in the twelfth transverse line. 
In the Perez manuscript, translated by Stephens and published 
in his “ Yucatan,” Vol. 11, we find it stated that one Ajpula died 
“in the year 4 Kan, the 18th day of the month Zip on 9 Ymix.” 
The year 4 Kan begins with the column of our table which has 
4 as its top figure; the third month (Zip) will then be the one 
with 5 at the top; running down this to the eighteenth transverse 
line, we find the figure g, we also find that the 18th day of the 
Kan column is Ymix, agreeing exactly with the date given. 
In the Manuscript Troano we find another 
method of giving dates, which is very com- pepo 
mon throughout the work, thus: + + * (black) 
This, according to my interpretation, signifies 13 Ahau of the 
13th month. As neither the year nor the day of the month 1S 
given, it is evident that we may find four dates satisfying the de- 
mand. Turning to our table we commence with the Ahau in the 
Cauac column, which we find is the second day of the month. 
The 13 in the second transverse we find in the column having TT 
at the top; by counting Jack thirteen months (always including 
the one counted from and to) we find that the first month of the 
year is the one with 6 at the top, hence the year is 6 Cauac. The 
backward counting is exactly the reverse of the forward count- 
ing—count toward the left until the first colunin is reached, then 
return to the thirteenth and so on until the number of the month 
required is reached. 
Proceeding in the same way with the Ahau in the Kan, te 
and Ix columns, we find the years to be 4 Kan, 9 Muluc an 
3x; | 
We are now prepared to discuss the question as to whether & 
numerals and day characters are used in the manuscript simply 
as dates or not. 
By counting, I find there are about 235 recognizable columns
