Thus proceeding, they went casting them upon the mound of coals—now on — Florentine Codex

"And right before her image died a woman slave whom they had bought. The water merchants exhibited her; those who gained their livelihoods from water, those who brought water in boats, those who owned boats, those who lived on the water, the boat-makers, those who served water in the market place. Likewise they arrayed her, made offerings, and ornamented her; for she would go, when she died, to a place called Tlalocan. In the temple of the Tlalocs they opened her breast."

"The third month they called Toçoztontli. On the first day of this month they observed a feast to the god named Tlaloc, who is the god of rain. On this feast they slew many children upon the mountains. They offered them as sacrifices to this god and to his companions, so that they would give them water."

"And if the children went crying, if their tears kept flowing, if their tears kept falling, it was said, it was stated: "It will surely rain." Their tears signified rain. Therefore there was contentment; therefore ones heart was at rest. Thus they said: "Verily, already the rains will set in; verily, already we shall be rained on."

"The tenth month they named Xocotl uetzi. On the first day of this month, they observed a feast to the god of fire, named Xiuhtecutli or Ixcoçauhqui. On this feast they cast into the fire, alive, many slaves, bound hand and foot, and before they had quite died, they took them forth, dragging [them] out of the fire, in order to tear out their hearts before the image of this god."

"When the masters of the captives took their slaves to the temple where they were to slay them, they took them by the hair. And when they took them up the steps of the pyramid, some of the captives swooned, and their masters pulled them up and dragged them by the hair to the sacrificial stone where they were to die.Having brought them to the sacrificial stone, which was a stone of three hands in height, or a little more, and two in width, or almost, they threw them upon it, on their backs, and five [priests] seized them—two by the legs, two by the arms, and one by the head; and then came the priest who was to kill him. And he struck him with a flint [knife], held in both hands and made in the manner of a large lance head, between the breasts. And into the gash which he made, he thrust his hand and [[w:Human sacrifice in Aztec culture#Sacrifice ritual|tore from [the victim] his heart]]; and then he offered it to the sun and cast it into a gourd vessel."

"And so, they would kill some in the first month, called Cuahuitlehua, and others in the second, called Tlacaxipehualiztli, and others in the third, called Tozoztontli, and others in the fourth, called Huei Tozoztli, in such a way that they would sacrifice children during all the festivals until the rains would begin to fall in abundance."
