_ayauicalo_ refers to the _ayauhcalli_, "house of mist," the home of the
rain god, which Sahagun informs us was represented at the annual
festival by four small buildings near the water's edge, carefully
disposed to face the four cardinal points of the compass (Sahagun, _ubi
supra_).

In v. 8 the expression _tetzauhpilli_ (_tetzauhqui_, to frighten) may
be explained by the figure of Tlaloc, whose statue, says Duran, was that
of _un espantable monstruo, la cara muy fea_ (_ibid._).

The compound in v. 10, _nauhxiuhtica_, "after four years," appears to
refer to the souls of the departed brave ones, who, according to Aztec
mythology, passed to the heaven for four years and after that returned
to the terrestrial Paradise,--the palace of Tlaloc. (See my paper, _The
Journey of the Soul_, in _Proceedings of the Numismatic and Antiquarian
Society of Philadelphia, 1883_.)
