I am firmly convinced, for reasons which will be shown hereafter, 
that they are nothing more than orders of units or multipliers. 
Therefore, when they are spoken of as ‘* time periods,” or by the names

The typical and usual form of the ahau is shown in the first three 
glyphs of figure 9 (a, 4, c). This symbol denotes 360 days, which

the chuen, ahau, katun, and cycle will be discussed as the series by 
which their values are determined are examined,
