Glyph or Iconographic Image Description: 

This element for snake or serpent (coatl) has been carved from the compound sign for the place name, Coaixtlahuacan. It consists of a horizontal snake painted brown with a yellowish underbelly and a purple rattler. It is facing to our left, in profile. Its eye is white. Its tongue is red, white, and yellow, and bifurcated.

Added Analysis: 

The appearance of the serpent's tongue recalls the glyph for (tletl) (fire or flame) (see below, right). Perhaps the snake's bite caused awe, much as fire did. Serpents did have an association with fire and the fire divinity, Xiuhtecuhtli, as explained by Esther Pasztory (paraphrased by Ian Mursell). The presence of rattles is also important, even if artists often omitted them, because rattlesnakes ware significant in Mesoamerican cultures, as the study of rattlesnakes by Ian Mursell of Mexicolore also elaborates. A wooden, turquoise-mosaic pectoral in the shape of a snake is held in the British Museum, whose curators have written: "The Mexica considered serpents to be powerful, multifaceted creatures that could bridge the spheres (the underworld, water and sky) owing to their physical and mythical characteristics." Besides being an animal that was common in the central highlands, the coatl is the name of the first day of a thirteen-day calendrical cycle.
