Fig. 44. The Normal Forms of the Period Glyphs. Reading from left to right: baktun, katun, tun, uinal, kin.
Although the numerical values are expressed by position alone in some cases, in other cases use is made of Period Glyphs to make assurance doubly sure. These Period Glyphs represent the basic value of the positions which are to be multiplied by the accompanying numerals. For examples, see Figs. [44] and [45].
