It is certain that from the earliest times cases of what are undoubtedly epilepsy have been taken as positive indications of supernatural influence. "There is," says Emanuel Deutsch, "a peculiar something supposed to inhere in epilepsy. The Greeks called it a divine disease. Bacchantic and chorybantic furor were God-inspired stages. The Pythia uttered her oracles under the most distressing signs. Symptoms of convulsion were ever needed as a sign of the divine."[55] Much of the evidence for the supernatural in the New Testament rests upon cases that are obviously pathological in character. A man brings his son to Jesus and describes how "ofttimes he falleth into the fire, and oft into the water" (Matt. xvii. 15), and in another place (Mark ix. 18) the same patient is described as having a dumb spirit, "and wheresoever he taketh him, he teareth him; and he foameth, and gnasheth with his teeth, and pineth away." The response to the father's appeal for help is an exorcism of the possessing spirit such as one meets with in all savage culture. Between possession by a malignant spirit and domination by a god, the difference is clearly one of terminology alone. And at the side of the New Testament case just cited one may place this account from Polynesia, written by a very competent observer, and a missionary:-- "As soon as the god was supposed to have entered the priest, the latter became violently agitated and worked himself up to the highest pitch of apparent frenzy; the muscles of the limbs seemed convulsed, the body swelled, the countenance became terrific, the features distorted, the eyes wild and strained. In this state he often rolled on the earth, foaming at the mouth, as if labouring under the influence of the divinity by whom he was possessed, and in shrill cries, and often violent and indistinct sounds, revealed the will of the god."[56] Advancing to a higher culture stage than that indicated in the last passage, there is much evidence that Mohammed was subject to hallucinations, and many authorities have indicated epilepsy as their source. There is a tradition that someone who saw Mohammed while he was receiving one of his revelations observed that he seemed unconscious and was red in the face. Mohammed himself said:-- "Inspiration descendeth upon me in two ways. Sometimes Gabriel cometh and communicateth the revelation unto me, as one man unto another, and this is easy; at other times it affecteth me like the ringing of a bell, penetrating my very heart, and rending me as it were in pieces; and this it is which grievously afflicteth me." Emanuel Deutsch, although, in a passage already cited, recognising the religious significance attached to epilepsy, has the following curious comment:--
