this was a very poor apparition and clearly a projection of some transparent picture. Phylidor commanded the spirit to disappear and soon an apparition of Frederick the Great followed. When some visitors complained that the facial features weren't very clear, Phylidor replied that he was surprised that they expected to see more details in a ghost. Then Von der Eck confronted Phylidor with the question if it wasn't all just optical illusions. Phylidor threatened with terrible dangers that would be caused by this behavior. Von der Eck and other audience members then demanded to see Phylidor raise the devil, if he would still insist that he really had supernatural powers. He pleaded not to have to do this, but instead to raise the spirit of the deceased father of an Englishman in the audience as agreed upon a few days earlier. He conjured up this apparition, but the image showed a figure in too fashionable an outfit for someone who had died a few years before. In the meantime the smoke had become too irritating and some men called for light and wanted the door to be opened. Phylidor proposed to make King Heinrich IV appear, but couldn't calm his audience and accepted his defeat. Some of the men warned him that it would not end well if he was to perform his deceitful tricks again. Aftermath The morning after Phylidor's failed séance, he was told by the police not to perform his magic again, because it went "against religion and good manners", and he was ordered to leave Berlin. After Phylidor had left, Von der Eck examined the room and found some evidence that the apparitions were created by rear projection on a transparent screen in the wall. He also found traces of a metal wire that had been attached to the walls, which he thought was intended to ignite some combustible materials to create the illusion of the complete room being on fire. Vienna (February 1790 to January 1792) Phylidor had further developed his show when he came to Vienna and claimed to have perfected his ghostly apparitions with a totally new invention. He advertised his show in March 1790 as "Phantasmorasi, oder natürlicher Geister Erscheinungen" (Phantasmorasi, or natural ghost apparitions), besides very entertaining magnetic-mechanical experiments in his renewed Cabinet of Physics. Spectators would first gather and wait silently in an anteroom, until the physicist ordered them to
