# Torelli’s Chariot and Pole System (OL80)

Examine plates 8 or 18 from the entry on theatre machines in Diderot’s encyclopedia. If you were a historian that first discovered this piece of visual evidence labeled “theatre machine”, how would you describe how the machine works? In a minimum of 3 sentences describe everything you see in one of the two plates (8 or 18, not both). Your goal is to describe what you see in as much accurate detail as possible so that someone reading your description would understand exactly what the object looked like and how it operated. List names of your group at the start of your entry.

PLATE 8
With two subsets of floors beneath the main theatre floor, there was more room to enhance plays. The first subfloor housed items that would be used to bring the play to life, such as waves. It was on the second subfloor the mechanics actually happened. Drum-wheels and rollers would move the items on the first subfloor. This would give the impression of moving waves on the main floor, and then when there was no longer a need for waves, they would be stored in the first subfloor. When a situation called for something different, the second subfloor would move those instead.

PLATE 18
To enhance depth to the stage point B two columns that surface with a pull of a lever. Points D, L, and E form a pully system so that it will allow both points B to move right or left across the stage. Points N and F control the distance that will be moved. For example this can be used to create building structures, separate rooms… etc.

Plate VIII
This drawing shows many aspects of staging machinery which can be used to move actors around the stage. Figure 2 shows a standard model pulley that is used in the system while Figure 3 shows how the pulley and latches are positioned within the structure of the stage. Figure 1 expresses the entire stage being symmetrical and comprising of two elevators at each end. These elevators can be used as trap doors to re-position actors and other stage materials.

Plate 18 is a pulley system used to open trap doors onstage. This system uses two sets of pulleys that are hooked to a trap door on a roller. Two stagehands would be working the pulley system below the stage. One stagehand opens the door and one stagehand closes the door. The trap door is used for actors and/or props to enter the stage through the bottom where the trap is.

This machine is used for the Fly space above the theater stage. Above the theater stage, the Fly Space has many different riggings like, levels, pullies, rollers, etc… that come from the trap room above the fly space. They are there to help with carrying different stages, backgrounds, props, lightings for when the performance is taking place. Also, these are out of sight from the audience.

Plate 8 basically shows a cross section within the width of three floors. The first floor is the main stage that is visible to the crowd. There is a pulley system on the two sub-floors that basically sets up theatre reveals with gears that would adjust based on what is going on in the play.

My group analyzed figure 18. Section and elevation over the face[s] of the trap lifts with the starting-handle of the levers and the opening from the traps of the main stage, with the rollers on which the traps pass [in order] to open them when the need arises. What we took from this figure is that through a series of ropes and pullys on a permanent slot on the stage, a below section of the stage is able to rise and fall. This contraption can be used to change the design of the set by rising and dropping props such as trees. This contraption can also be used to elevate actors from from underneath the stage. We are assuming that this contraption was created so that set design can can be changed in a quick manner.
