What was the purpose of trapdoor in stage?

The purpose of a trapdoor in a stage is to allow actors, props, and scenery to enter and exit the stage from below while remaining hidden from the audience. This creates a sense of magic or surprise for the audience, as characters can seemingly appear and disappear at will.

Here are some specific uses of trapdoors:

* Character entrances and exits: A character can vanish by stepping through the trapdoor and reappear later on stage from a different entrance, creating a dramatic effect. This is often used for ghosts, villains, or magical characters.

* Prop movement: Trapdoors allow for the discreet movement of large props or sets on and off stage without disturbing the flow of the performance. This can be used for things like furniture, treasure chests, or even a whole room!

* Special effects: Trapdoors can be used to create special effects, such as a character falling through the floor or a sudden explosion.

* Scenic changes: By using trapdoors, sets and scenery can be quickly changed while the audience is distracted by other aspects of the performance.

In essence, trapdoors are a crucial element of stagecraft that add an element of spectacle, surprise, and illusion to theatrical performances.
