The Toledo Letter, 1184
A letter supposedly written by the astrologers of Toledo began circulating throughout Europe in 1184. It predicted the world would end in September 1186, amidst awful calamities.

To expose Redheffer, they commissioned a local engineer to build a similar machine, and when they showed this to Redheffer he fled the city.

Carlos Castaneda and Don Juan, 1968
In 1968 Carlos Castaneda, a graduate student in anthropology at the University of California at Los Angeles (UCLA), published The Teachings of Don Juan: A Yaqui Way of Knowledge. It described his encounters with Don Juan Matus, a Yaqui shaman from Mexico. Don Juan supposedly trained Castaneda in ancient forms of knowledge, such as how to use drugs to communicate with animals (or even to become an animal). Castaneda's book became a bestseller and was an important influence on the New Age movement. Castaneda was awarded a doctorate by UCLA in 1972.
