The H.P. Lovecraft Wiki

. . . 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.

This subject contains information from the "Lovecraft Circle" Myth Cycles, and while guided by HPL are not based on his work alone. 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.

... And it has been said that another realm, beyond that of common occurrence, lies waiting those who dare to enter. Many have tried drugs and herbs while others recommend to me the use of mesmerism to journey to these bizarre and distant worlds. Within, much can be learned first-hand . . . others have told of the great artist, Rhydagand, who needed but to paint a picture of whither he wished to journey, and then by sleeping near this drawing was magically transported there... those who would travel in these, the darkest parts of this strange world, do well to protect themselves against the foul dog-like denizens of this unholy realm. This protection is partially afforded by that sign of ancient Aegyptus, the scholar says, the ankh, which is reverenced as much as anything by the beasts that live in the pestiferous burrows that dot this land . . . this odd man, traveler to foreign realms, related the story of Ghadamon to me. How the thing had been spawned on the flesh of human brains and secreted beneath a great lake in a fearsome world of darkness where it would lie for eternal ages, feeding, growing, and waiting. This man did claim that Ghadamon is coming and coming soon. I deemed him mad, but soon later he was murdered by the Oriental One . ...
