Hongos monteses in Durán's Historia de las Indias de Nueva España

These excerpts from Diego Durán's chronicle gather three sixteenth-century passages on raw "mountain mushrooms" used in Mexica royal festivals. The translation is prepared for the archive from the public-domain 1867 Spanish edition edited by José F. Ramírez; spelling in the Spanish tab is lightly normalized from the printed text and OCR.

Tízoc's Coronation Feast

The next day, before dawn, Tlacaelel rose and went to the king's chamber. Waking him, he had him dressed as on the day before, and the two of them went out to dance with several lords. He told the king that his days were now few and that he wished to spend them in his contentment and joy, since in the other world he would no longer dance or sing or enjoy the fragrance of roses and scented flowers, from which the lords who had already passed on were deprived.

As soon as they came out, the great men of the court arrived with rich roses, most finely worked, and garlands of roses and splendid gilded bouquets, and they gave them to the two kings of the two provinces. All the lords and great men of the provinces rose, and to make the feast more solemn they all ate some mountain mushrooms, which they say cause the loss of one's senses. Thus they went out, fully adorned, to the dance. After they had danced for a time, the king again clothed all the lords and gave them rich mantles and jewels, in the same manner already described. This dance and feast and meal, and the distribution of mantles and jewels to all those named above, lasted four days.

Ahuitzotl's Coronation: Durán's Note on Mushrooms and Intoxication

I have noted one thing throughout this whole history: it never mentions that they drank wine of any kind in order to become intoxicated, but only mountain mushrooms. They ate these raw, and with them, the history says, they made themselves merry and rejoiced and went somewhat out of their senses. It never mentions wine except for sacrifices or funerals; it only mentions the abundance of cacao that was drunk at these solemnities.

Motecuhzoma's Feast of Revelations

When the sacrifice was finished, and the temple steps and courtyard were bathed in human blood, from there they all went to eat raw mushrooms. With that food they all went out of their judgment and became worse than if they had drunk a great deal of wine: so intoxicated and out of their senses that many of them killed themselves with their own hands. Through the force of those mushrooms, they saw visions and had revelations of the future, the devil speaking to them in that intoxication.

After all this was finished and they had returned to themselves, the lords of Tlaxcala, Huexotzinco, Cholula, and Tliliuhquitepec asked royal permission to leave, which was immediately granted. They were given jewels and rich things, each lord receiving weapons and shields with their devices made of rich feathers.

From that day, the history says, Motecuhzoma invited the enemy kings and lords three times a year and made them a great feast. One was at the feast they called the Feast of the Lords; another at the great feast of the banners; and another when they all ate mushrooms, which they called the Feast of Revelations.
