In the shape of the goddess of the waters (Chalchiuhtlicue, Plate 16), close kin to Tlaloc, matter appears gifted with the power of salvation: vapour, freed from the great mass of water rises heavenward only to return once more to earth after having been made fertile by the sun so that it may create life on earth. Doubtless because of her permanent contact with the celestial spheres, the goddess is invested with the high faculty of purifying. It is she who is the baptismal ceremony frees from the newborn child from impurity.
