Quiyauh (MH835v)

Quiyahuitl is a day sign in the 260-day divinatory calendar, the tonalpohualli, which gives it a religious significance. If this is a calendrical name, the numerical coefficient has dropped away. Because of colonial edicts to stop using the tonalpohualli as a source for names, one thing that happened is that the companion numbers were dropped, perhaps as a stopgap measure to reduce the sacred nature of the name. See Norma Angélica Castilla Palma, "Las huellas del oficio y lo sagrado en los nombres nahuas de familias y barrios de Cholula," Dimensión Antropológica v. 65 (sept.-dic. 2015), 186. While the radiating lines of (perhaps) light are somewhat rare, below is another example of a raindrop with some shimmer. The Quiyauh glyph from MH660v has some appendages, but these are less identifiable. Some rain glyphs are painted turquoise blue, a different reminder of their preciosity.
