. . . The Book of Eibon, that strangest and rarest of occult forgotten volumes ... is said to have come down through a series of manifold translations from a prehistoric original written in the lost language of Hyperborea.
~ Clark Ashton Smith , "Ubbo-Sathla"

The Book of Eibon, also known as the Liber Ivonis or Livre d'Eibon, is a grimoire by the magician Eibon of Mhu-Thulan.

The book was passed down by secret cults to the present day. Never printed until the 20th century, there are many editions which vary widely, from tablets to scrolls. It is a key text in the Tsathogguan Cycle.
