Camille Flammarion's Flammarion Engraving

Origin
Camille Flammarion was an astronomer, author, and believer in psychic phenomenon. One of his many theories about the supernatural was that ghosts were not spirits that had not moved on, but were psychic recordings.

He believed in the "stone tape" theory. This is the belief that ghosts and hauntings were recordings from other people that were imprinted onto objects during times of heighten emotional or traumatic states. These could later be replayed under certain conditions.

Effects
The user may imprint a memory or message onto the engraving to be activated later. The user can choose what or who may activate it.

It was often used as a means of storing instructions or messages for other agents. Usage of the artifact has declined since the advent of answering machines and video cameras.

Collection
Collected by early agents of Warehouse 13. Artie jokes that nearly every item in the Warehouse is some kind of stone tape.
