The other number sacred to the nagualists was seven. I have, in a former essay, given various reasons for believing that this was not derived from the seven days of the Christian week, but directly from the native calendar.[42-*] Nuñez de la Vega tells us that the patron of the seventh day was Cuculcan, “the Feathered Serpent,” and that many nagualists chose him as their special protector. As already seen, in Guatemala the child finally accepted its naual when seven years old; and among some of the Nahuatl tribes of Mexico the tonal and the calendar name was formally assigned on the seventh day after birth.[42-†] From similar impressions the Cakchiquels of Guatemala maintained that when the lightning strikes the earth the “thunder stone” sinks into the soil, but rises to the surface after seven years.[42-‡]
The three and the seven were the ruling numbers in the genealogical trees of the Pipiles of San Salvador. The “tree” was painted with seven branches representing degrees of relationship within which marriage was forbidden unless a man had performed some distinguished exploit in war, when he could marry beyond the nearest three degrees of relationship.[42-§] Another combination of 3 and 7, by multiplication, explains the customs among the Mixes of deserting for 21 days a house in which a death has occurred.[42-‖]
The indications are that the nagualists derived these numbers from the third and seventh days of the calendar “month” of twenty days. Tepeololtec, the Cave God, was patron of the third day and also “Lord of Animals,” the transformation into which was the test of nagualistic power.[42-¶] Tlaloc, god of the mountains and the rains, to whom the seventh day was hallowed, was represented by the nagualistic symbol of a snake doubled and twisted on itself, and was generally portrayed in connection with the “Feathered Serpent” (Quetzalcoatl, Cuculchan, Gukumatz, all names meaning this), represented as carrying his medicine bag, xiquipilli, and incensory, the apparatus of the native illuminati, his robe marked with the sign of the cross to show that he was Lord of the Four Winds and of Life.[43-*]
26. The nagualistic rites were highly symbolic, and the symbols used had clearly defined meanings, which enable us to analyze the religious ideas underlying this mysterious cult.
The most important symbol was Fire. It was regarded as the primal element and the immediate source of life. Father Nicolas de Leon has the following suggestive passage in this connection:
“If any of their old superstitions has remained more deeply rooted than another in the hearts of these Indians, both men and women, it is this about fire and its worship, and about making new fire and preserving it for a year in secret places. We should be on the watch for this, and when in their confessions they speak of what the Fire said and how the Fire wept, expressions which we are apt to pass by as unintelligible, we must lay our hands on them for reprehension. We should also be on the watch for their baptism by Fire, a ceremony called the yiahuiltoca,[43-†] shortly after the birth of a child when they bestow on it the surnames; nor must the lying-in women and their assistants be permitted to speak of Fire as the father and mother of all things and the author of nature; because it is a common saying with them that Fire is present at the birth and death of every creature.”
This curious ceremony derived its name from the yiahuitli, a plant not unlike the absinthe, the powdered leaves of which, according to Father Sahagun, the natives were accustomed to throw into the flames as an offering to the fire.[43-‡] Long after the conquest, and probably to this day, the same custom prevails in Mexico, the fumes and odor of the burning leaves being considered very salubrious and purifying to the air of the sick room[43-§]
The word yiahuiltoca means “the throwing of the yiauhtli” (from toca, to throw upon with the hands). Another name for the ceremony, according to Father Vetancurt, who wrote a century later than Leon, was apehualco, which has substantially the same meaning, “a throwing upon” or “a throwing away.”[44-*] He adds the interesting particulars that it was celebrated on the fourth day after the birth of the child, during which time it was deemed essential to keep the fire burning in the house, but not to permit any of it to be carried out, as that would bring bad luck to the child.
Jacinto de la Serna also describes this ceremony, to which he gives the name tlecuixtliliztli, “which means that they pass the infant over the fire;” and elsewhere he adds: “The worship of fire is the greatest stumbling-block to these wretched idolaters.”[44-†]
27. Other ceremonies connected with fire worship took place in connection with the manufacture of the pulque, or octli, the fermented liquor obtained from the sap of the maguey plant. The writer just quoted, de Vetancurt, states that the natives in his day, when they had brewed the new pulque and it was ready to be drunk, first built a fire, walked in procession around it and threw some of the new liquor into the flames, chanting the while an invocation to the god of inebriation, Tezcatzoncatl, to descend and be present with them.
