ilhuicatl (Azca24)
This painted black-line drawing of the sky (ilhuicatl) with stars is an element in the compound glyph for Motecuhzoma Ilhuicamina. The sky is a tan color, and the stars are white. The sky and stars fill a half circle. In the original glyph, an arrow pierces the sky. We have digitally removed the arrow, reconstructing the space where it had appeared. If it had not been for the arrow, perhaps another star would have filled that space. At any rate, there are five seven-to-eight pointed stars.

We have no gloss for this element, as the compound from which it came was not glossed. Still, it is similar enough in content and appearance, that we feel certain of the analysis. Stars can come in the shape of eyes and simple white circular objects, or they can have points much like the stars in European art. Skies can be a rectangular band, as seen in the Codex Mendoza, or circular. Some are entirely round, some are half circles, or a filled U-shape. See examples below.
