Ce Acatl (Mdz2r)
This combined simplex glyph and notation for the solar year (xihuitl) date One Reed has the notation (a single one, ce) to the right of the glyph for reed (acatl). This is the usual representation of the reed as found in calendrical glyphs--and many other glyphs--upright, in a frontal view, and with the decorations of feathers, much like the arrow (mitl) or dart. At the bottom of the short reed is a small, symbolic apantli (canal or waterway), shown in cross-section. The notation for the number one in this case is a circle with a smaller concentrical circle.

Some notations for ones in the Codex Mendoza, alternatively, will have dots and some will be empty circles. The notations will also have a placement that varies (see below for other examples). The entire date (including the background) is painted a turquoise blue (xihuitl) color, representing the intentional use of the homophone for year (also xihuitl), and it is enclosed in a black line-drawing box (which is not shown here), also meant to say "year." Calendrics were an important element in the Nahuas' religious views of the cosmos.

ome acatl. Detail from the "Teocalli de la Guerra Sagrada." A much smaller one also appears at the top of the cane, near the square that surrounds the date glyph, but it is not clear whether it should be added into the notation.
