Un signo de color turquesa que tiene el sentido de guerra, que aparece en el Códice Mendoza (ff. 2v, 10r, 12r, etc.) al lado del difrasismo (o digrafismo) rodela y flechas, es similar a "imágenes de Tezcatlipoca en el Códice Telleriano-Remensis (en adelante TR) (ff. 3v, 6v), con la glosa xiuhatlatli, 'atlatl de turquesa', así que en el Mendoza debe tratarse del mismo implemento."
