Inigo Jones (July 15, 1573 - June 21, 1652) is the first significant British architect of the modern period, and the first to bring Italianate Renaissance architecture to England. He left his mark on London by single buildings, such as the Banqueting House, Whitehall, and in area design for Covent Garden square which became a model for future developments in the West End. He also made major contributions to stage design by his work as theatrical designer for several dozen masques, most by royal command and many in collaboration with Ben Jonson.
He is credited with introducing movable scenery and the proscenium arch to English theatre.

Method for dropping a cloth from a flying bar. It consists of a bar which attaches to a standard flying bar, and is able to spin around. The bar has prongs welded to it on which the drop is hung (drop has grommetted holes in the top which hook onto the prongs). Normally these prongs are above horizontal, so the drop stays hung. On cue, the pole is rotated so that the prongs point downwards, and the drop consequently falls.

MISE EN SCÉNE
Although the term literally "placing on stage" in French, the Mise en Scene refers to much more than the setting of a performance or event. The term describes all of the visual aspects of a setting - props, lighting, costume as well as set design, and how the details can contribute to the telling of the story.
MOBILE ELEVATED WORK PLATFORM (MEWP)
(often abbreviated to MEWP) A piece of access platform with a wheeled base, which can sometimes be self-propelled by the operator. The best known manufacturer is GENIE.
A scale model provided by the set designer to help all the technical departments to co-ordinate and plan a production. Used as a reference when building, painting, dressing and lighting the set. The first stage of model-making is the WHITE CARD model which shows the form of the set, but not the detail of painting / texture / colour. When that's been approved by the director, and has been roughly budgeted, the final model is produced which should look identical to the finished set on stage. This is used as a reference by scenic artists and lighting designer etc.

A scissor lift is a type of aerial work platform (AWP), also known as an aerial device, elevating work platform (EWP), or mobile elevating work platform (MEWP). The AWP is a mechanical device used to provide temporary access for people or equipment to inaccessible areas, usually at height. The MEWP can usually be driven around the work area by the operator at height to provide safe access to a wide area, on a flat floor. Scissor lifts have also been used in scenic automation to provide a moveable platform, often built onto a moving base. The scissor lift is used because it is a self-contained device which requires no construction for it to operate within, and which does not extend beyond the horizontal dimensions of the platform.
The mechanism to achieve the vertical lift is the use of linked, folding supports in a criss-cross X pattern, known as a pantograph (or scissor mechanism). The upward motion is achieved by the application of pressure to the outside of the lowest set of supports, elongating the crossing pattern, and propelling the work platform vertically. The platform may also have an extending bridge section to allow closer access to the work area, because of the inherent limits of vertical-only movement.
The contraction of the scissor action can be hydraulic, pneumatic or mechanical (via a leadscrew or rack and pinion system). Depending on the power system employed on the lift, it may require no power to enter descent mode, but rather a simple release of hydraulic or pneumatic pressure. This is the main reason that these methods of powering the lifts are preferred, as it allows a fail-safe option of returning the platform to the ground by release of a manual valve.
