After several nights of pleas, of the Iztacmixcoátl (via láctea) a voice was listened to saying: " Mixcóatl will send rain to them that as much they ask for". The Citlalnenque (Virgin Star) will take before the dawn the Tlaol to them (Corn) for its sustenance, with the condition of which their cores, instead of going to the sun, will come to populate the Iztacmixcóatl (Cloud Serpent) ".

Right away, the rain began to approach the Earth, to the Tlalli, pushed by Ehécatl (air). The center of the Iztacmixcóatl nebula the Travelling Star was come off, the Citlalnenque, illuminating with its hair to the tatemada Tlalli. To his passage by the Hill of the Star it dropped something to the Tlamatini that named the Citlalcuítlatl (Excrement of Stars), but the impact left them without knowledge.

With the light of the day they noticed that it had passed over them a great storm drawing themselves between gray clouds and blue celestial beautiful arcoiris.

When remembering the message of the Gods went to the place where small knolls of " golden larvae " saw fall the Citlalcuítlatl finding. At the same time they saw that thousands of winged black ants took those " larvae " leading them to different places to autosepultar itself in the humid Earth, with its golden load.

Spent some days they brought forth the repollos of corn and frijol in the holes where the ants had buried themselves. The " golden larvae " of celestial origin, flattery of the Gods of the Omeyocan had become the maize and frijol black, for food of the macehuales.

In another temporary space, Xochimilco would have to create chinampa where the golden maize, with black beens, would grow up, this one, trepador on the ramajes of the verticals ahuejotes. The memory of the old ones remembers: " Of the opened dry cases frijol chinampero in rows like black ants was seen that fell in the trunk of ahuejotes ".

Of the stellar request so that the cores of the macehuales went to populate the Iztacmixcóatl, the Tlamatini chinamperos drew up acalote of Cuemanco to similarity of the Cloud Serpent, and all chinampería gave the architectonic outline him of the cosmos. Since then, the chinampero xochimilca sailed in his acallis (canoes) on the Iztacmixcóatl, the decembrina Cloud Serpent, month in which the auroras paint of red the horizon of volcanos, and acalote of Cuemanco is transformed into a cloud way, sidereal.
