From Claude Levi-Strauss' book 'Myth and Meaning: Cracking the Code of Culture:

... a puzzling observation recorded by a Spanish missionary in Peru, Father P.J. de Arrigia, at the end of the sixteenth century, and published in his 'Extirpacion de la Idolatria del Peru' (Lima 1621). He noted that in a certain part of Peru of his time, in times of bitter cold the priest called all the inhabitants who were known to have been born feet first, or who had a harelip, or who were twins. They were accused of being responsible for the cold because, it was said, they had eaten salt and peppers, and were ordered to repent and to confess their sins.
