Fig. 50. Examples of the use of bar and dot numerals with period, day, or month signs. The translation of each glyph appears below it.
Examples of the normal-form numerals as used with the day, month, and period glyphs in both the inscriptions and the codices are shown in figure [50]. Under each is given its meaning in English.[[66]] The student is advised to familiarize himself with these forms, since on his ability to recognize them will largely depend his progress in reading the inscriptions. This figure illustrates the use of all the foregoing forms except the sign for 20 in figure [45] and the sign for zero in figure [46]. As these two forms never occur with day, month, or period glyphs, and as they have been found only in the codices, examples showing their use will not be given until Chapter VI is reached, which treats of the codices exclusively.
