Asrah Levitation (aka Rostrum)
Designer: Servais Le Roy
The Asrah levitation is an illusion where the assistant lies a table or couch. The assistant is then fully covered with a cloth and levitated under the cloth. The couch is removed to show no connection. The assistant floats well over the magician’s head. Finally, after the assistant has floated up and down, the magician approaches the floating assistant and suddenly removes the cloth covering her. Just as the cloth is pulled off, the assistant vanishes visibly, before the eyes of the audience with nowhere for her to be.
The Asrah levitation is credited to Servais Le Roy and was first performed in 1901, according to Magic: 1400s – 1950s.
