The ancient Greek text "On the Sacred Disease", which was written around 400BC and attributed to Hippocrates, is an early medical record about epilepsy; as the title suggests, it refers to the belief that epilepsy was associated with divinity or originated from supernatural. It cites contemporary beliefs that different symptoms of epileptic fits originate from different deities, and that seizures were caused by a god entering or influencing the body. However, the text argues against this belief, stating that "[the disease] appears to me to be nowise more divine nor more sacred than other diseases, but has a natural cause". It suggests that it is impious and ignorant to claim that divine influence would render a body unclean; rather, it argues that epilepsy originates from imbalanced humours and is an inheritable condition. As such, the idea that epilepsy was in some way sacred--as well as the idea that it was a physiological condition with no supernatural aspects--were both extant in ancient Greece (although it should be noted that Owsei Temkin's The Falling Sickness: A History of Epilepsy from the Greeks to the Beginnings of Modern Neurology observes that "the popular concept of the 'sacred disease' may have been broader than that of the physician's" (17), encompassing other nervous conditions, though still centering on epilepsy). Temkin's book provides other discussions of how epilepsy was seen as having a spiritual dimension throughout history, though as I don't have a complete copy on hand, I can't add too much about what historical claims he makes beyond this detail.
