Chalco (Mdz41r)

The glyphs representing Chalco vary somewhat, and the chalchihuitl can be combined with the compound glyph for Atenco (see below, right). The reason for the red ring is unclear. The external patterns, however, may have some purpose such as to convey shine and/or preciosity. Note some other examples of possible resplendence in such things as turquoise stones, mirrors, or the sun, below right. The green center appears to represent most closely the greenstone that provides the name of chalchihuitl). The mottled effect, using two shades of green, may intend to convey something of the shape or variable color of the stone. Local jade was highly prized for its color, like water, which is essential for life. Greenstones were tribute items that were provided by the commoners to the rulers. Precious greenstones were also spoken of as metaphors for children. That, said, the green stone was only used in this compound glyph to call forth the phonetic "chal," meaning "in the hollow." The place does not really have a significance relating to the precious stone.
