This seems to be a song of victory to celebrate an attack upon
Atlixco by the ruler of Tezcuco, the famous Nezahualpilli. This
monarch died in 1516, and therefore the song must antedate this
period, if it is genuine. It has every intrinsic evidence of
antiquity, and I think may justly be classed among those preserved
from a time anterior to the Conquest. According to the chronologies
preserved, the attack of Nezahualpilli upon Atlixco was in the year
XI _tochtli_, which corresponds to 1490, two years before the
discovery by Columbus (see Orozco y Berra, _Hist. Antigua de Mexico_,
Tom. III, p. 399).
