Matlactli Cuauhtli (CQ)
This simplex glyph-plus-notation represents the personal name (and date) Matlactli Cuauhtli (Ten Eagle). It consists of ten ones above and to the side of the head of an eagle, shown in profile, facing to the viewer's left. The ones are colored in a repeating pattern, turquoise-yellow-red. Seven ones form a horizontal line at the top and three go down the right side. Unusually, they are not presented as two groups of five, which would be a mathematical equation. The eagle's head is white (or neutral) with black feathers around its neck. Its yellow beak is closed. Its eye may be open; it is left neutral.
