In the miracle plays and mysteries staged for the populace, realism was the desired effect.
“In the miracle plays and mysteries staged for the populace, realism was the desired effect. A system of weights and pulleys resurrected Jesus from the tomb and lifted him to a ceiling of clouds. Angels and devils were made to appear magically through trapdoors; Hell opened and closed its monstrous mouth, and Noah’s flood inundated the stage from casks of water overturned backstage while stone-filled barrels turned by cranks resounded with thunder. When John the Baptist was decapitated, the actor was whisked away so cunningly in exchange for a fake corpse and fake head spilling ox blood that the audience shrieked in excitement. Actors playing Jesus sometimes remained tied to the cross reciting verses for three hours.”
