That some such use of poisonous fungi as has been shown exists among the tribes of Siberia was made by other nations, would be difficult to prove in the absence of direct testimony, but many incidental references are encountered which the reflective mind must consider with care before rejecting them as absolutely irrelevant in this connection. The Mexicans, as we learn from Sahagun, were not ignorant of the mushroom, which is described as the basis of one of their festivals. He says that they ate the nanacatl, a poisonous fungus which intoxicated as much as wine; after eating it, they assembled in a plain, where they danced and sang by night and by day to their fullest desire. This was on the first day, because on the following day they all wept bitterly, and they said that they were cleaning themselves and washing their eyes and faces with their tears.[17] It is true that Sahagun does not describe any specially revolting feature in this orgy, but it is equally patent that he is describing from hearsay, and, probably, he was not allowed to know too much. In a second reference to this fungus, which he now calls teo-nanacatl, he alludes to the toxic properties, which coincide closely with those of the mushrooms noted in Siberia and on the northwest coast of America. “There are some mushrooms in this country which are called teo-nanacatl. They grow under the grass in the fields and plains; ... they are hurtful to the throat and intoxicate; ... those who eat them see visions and feel flutterings in the heart; those who eat many of them are excited to lust, and even so if they eat but few.”[18] The proof is not at all conclusive that this intoxication was produced as among the Siberian and Cape Flattery tribes; but it is very odd that the Aztecs should eat mushrooms for the same purpose; that they should hold their dance out in a plain and by night (that is, in a place as remote as possible from Father Sahagun’s inspection). On the second day, to trust Sahagun’s explanation, they would appear to have bewailed their behavior on the first; although it should be remarked here that ceremonial weeping has not been unknown to the American aborigines, and may, in this case, have been induced by causes not revealed to the stranger. Lastly, it is important to note that this poisonous fungus was a violent excitant, a nervous irritant, and an aphrodisiac. Another early Spanish observer, also cited by Kingsborough, describes them in these terms:— “They had another kind of drunkenness, ... which was with small fungi or mushrooms, ... which are eaten raw, and, on account of being bitter, they drink after them or eat with them a little honey of bees, and shortly after that they see a thousand visions, especially snakes. “They went raving mad, running about the streets in a wild state (‘bestial embriaguez’). They called these fungi ‘teo-na-m-catl,’ a word meaning ‘bread of the gods.’” This author does not allude to any effect upon the kidneys.[19]
