nahui yohualli (Azca12)

This example of iconography contains four glyphs for yohualli (night) and three glyphs for ilhuitl (day), suggesting a term of three days and four nights during which a comet or shooting stars (popocacitlalin) appeared in the sky. The comet has an elongated, vertical, wavy outline that contains all these glyphs plus some additional dotted (perhaps more distant) stars (citlalin)and, at the lower end, is one more very large star, drawn in European stylistics and painted yellow. The only other color in the comet is found in the red portions that alternate with white in the spiraling outer rings of the ilhuitl signs. The glyphs for night have four small circles within a larger circle, just a bit smaller than the outer circles of the day signs.
