Xiuhnel (MH483r)

The small trapezoidal and diamond shapes of this glyph are likely turquoise pieces of the type that were used in mosaics (tesserae). Some Matrícula de Huexotzinco examples of the name Xiuhnel have turquoise-blue coloring which supports this interpretation for the lot of them. For extensive examples of turquoise tesserae, see the appendices of Conceptualization of 'Xihuitl' (2008), by Matzumi Izeki. This collection also includes an iconographic example of turquoise (xihuitl) that shows pieces of the stone made into a small, round mosaic (below).

At first glance the name Xiuhnel appears to be a compound of xihuitl (turquoise) and nelli (true). James Lockhart suggests that -nel-, when in combinations, could lose that meaning, as noted in the Online Nahuatl Dictionary under the term nelli. But there is a xiuhnel meaning "incapable" according to Wimmer 2004 (included in the Gran Diccionario Náhuatl). Perhaps more appealing for a person's name is the one provided by a human origin story written in Nahuatl in 1558. In that story Xiuhnel was a cloud serpent, according to an article by Willard Gingerich. Some also say Xiuhnel is the morning star. If so, then the diamonds shapes may relate to that.
