Victor Hennequin
Victor Hennequin was a French medium who published several works in the 19th Century. He was an editor of La Démocratie Pacifique and, after 1848, a member of the National Assembly of France. He was a young barrister "infatuated with the reveries of Fourier" (Eliphas Levi, The History of Magic, Book VII, Chapter III). Being banished as an after consequence of the French coup of 1851, he took up table-turning during his enforced inactvity; he soon fell victim to mediomania and believed himself an instrument for the revelations of the soul of the earth. He published a book entitled Save the Human Race (1853); it was a mix of socialistic and Christian reminiscences.
In a final work of which only one volume was issued, Victor Hennequin represents God in the guise of an immense polypus located at the centre of Earth, having antennae and horns turned inwards like tendrils all over his brain, as also over that of his wife Octavia. Soon afterwards it was reported that Victor Hennequin had died from the consequences of a maniacal paroxysm in a madhouse. His madness is said otherwise to have been partial or characterized by many lucid intervals. His second work was Religion. It preached the doctrine of reincarnation with periodical changes of sex. It described the Deity as an infinite substance in which circulated myriads of soul-entities.
The occult writer Eliphas Levi presents the case of Victor Hennequin as an example of the dangers of trying to develop mediumistic powers. "The reiterated efforts of a healthy person to develop mediumistic faculties cause fatigue, disease and may even derange reason." (Levi, The History of Magic, Book VII, Chapter III).
