1881. ] The Manuscript Troano. 635 
“There was another number which they called Ua Katun and 
which served them as a key to find the Katunes; according to the 
order of its march it falls on the Uayed haaé, and revolves to the 
end of certain years, Katunes 13,9, 5, I, 10, 6,2, II, 7, 3, 12,8, 4.” 
By commencing at the bottom of either column of our table of 
years, and running up, we will find precisely these numbers, and 
in the order here given. It is scarcely possible these could have 
been obtained except by a table of years similar to those we have 
given. Be this as it may, the fact that these numerals and char- 
acters, as here interpreted, include a continuous period, is too 
plain to be ignored. The agreement in so many numbers and 
the order in which they come cannot be accidental. 
From this we are justified in concluding, tst. That these day 
characters are used simply to represent days; 2d. That the red 
numerals are used to denote the days or years of the Maya 
“week” (as their period of 13 days and years has been termed, 
though they applied no name to it), which is corroborated by the 
fact that with the exception of two on the title page, none in the 
manuscript denote a greater number than 13 (there is one other 
apparent exception, but the additional dot is a blotch or evident mis- 
take); 3d, That the day columns are to be read from the top down- 
wards; 4th. That Landa’s characters for the Maya days are correct; 
~ and 5th. That the work is some kind of a calendar, probably con- 
taining directions to be followed by the priests and people in refer- 
€nce to their religious duties. Now let us apply our theory to 
the day columns and numerals found in some of the other 
plates, 
We select as our first example the column in the lower division 
of Plate xxvr, as here both the red and black numerals are 13 
throughout, The day characters are those for Ahau, Eb, Kan, 
Cib and Lamat, in the order here given. According to the inter- 
Pretation suggested, the red numerals refer to the days of the week 
and the black to the days of the month. Proceeding upon this 
assumption, we will now try to find out, by using these numbers, 
in what years 13 Ahau, 13 Eb, 13 Kan, 13 Cib and 13 Lamat are 
to be found in the 1 3th month. The result is as follows : 
13 Ahau. 17 Bb ap Kee. 137 Cib, = 13 Lamat.
