Some written observations under the influence of the doctrine of Catholicism account the use of the mushroom among the Montezumanic people. Allegedly, during the emperor's coronation ceremony, many prisoners were sacrificed, had their flesh eaten, and their hearts removed. Those who were invited guests to the feast ate mushrooms, which Diego Durán describes as causing those who ate them to go insane. After the defeat of the Aztecs, the Spanish forbade traditional religious practices and rituals that they considered "pagan idolatry", including ceremonial mushroom use.
