It occurred to the writer that the expression tititl may have had reference to the act of sexual impregnation, as in the case of Tlazolteotl (q.v.), who “widens herself, stretches herself out” at the foot of the teocalli of Uitzilopochtli, when she is impregnated by that deity. This consideration scarcely seems to apply to the present instance, however, and that indicated above appears preferable.
