Ummo

From The Book of THoTH (Leaves of Wisdom)

Ummo is a blanket term to describe a series of decades-long claims that aliens from the planet Ummo were communicating with persons on the earth. Most Ummo information was in the form of many detailed documents and letters sent to various esoteric groups or UFO enthusiasts. The Ummo affair was subject to much mainstream attention in France and Spain during the 1960's and 1970's, and a degree of interest remains regarding the subject.

General consensus is that the entire affair was an elaborate hoax. The culprit (or culprits) is unknown, but a Jose Luis Jordan Pena has claimed responsibility for instigating the Ummo affair. [1]

However, some contend there may be at least a measure truth in the matter, and there are a few small groups of devotees, such as "a strange Bolivian cult called the Daughters of Ummo" [2]. Regardless of any ultimate explanation, the Ummo affair is one of the most intriguing (and most detailed) UFO-related events in recent decades. Dr. Jacques Vallee has said the Ummo documents might be a real-world analogue of the fictional creators of Borges' "Tlön, Uqbar, Orbis Tertius".
