Marshall H. Saville, Turquois mosaic art in ancient Mexico (1922)
“ Above a horizontal band just over the bottom of the inner encircling rim is a hieroglyph. It is the well-known glyph for Culhuacan, or Colhuacan, the name of an important town in the valley of Mexico in ancient times. The form of the glyph, a mountain with a curved peak, is derived from the tradition that the Nahuan people originated where there was a mountain with a curved peak, called in the Nahuan language Culhuacan. ”
