Ventriloquism emerged as a religious practice that branched off from necromancy.
Necromancy was a form of divination that involved communicating with the dead to predict the future. Gastromancy (ventriloquism) had the same objective, but with a different technique.
Ventriloquists could supposedly converse with the dead and divine the future but, for such a bold claim to be credible, the dead needed to talk back. And they did. The creepy disembodied voices of the unliving spoke through the stomach noises of a gastromancer because, well, he had demons living in his stomach. Unsurprisingly, our word “ventriloquism” comes from the Latin venter (belly) and loqui (speak), which gives us a term meaning “to speak from the stomach.” In ancient Greece, ventriloquists were also called “engastrimyths”.
Let’s get this straight. The souls of the dead lived in the stomach of a ventriloquist. The noises made by a ventriloquist’s stomach were the voices of the dead telling fortunes. That sounds about right.
Ventriloquism continued its dangerous tradition into the Middle Ages when throwing your voice could get you thrown off a cliff. On the other hand, a skilled ventriloquist priest could perform spectacularly convincing exorcisms.
When stage magic became more profitable than fortune-telling, ventriloquy’s relationship with demonic possession broke and speaking through a dummy turned performance art.
