by one stagehand. The front curtain is raised and lowered using the same technique as the backdrop. It is the heaviest curtain, but one strong man can raise and lower it. reconstructed and have been used in experimental productions in the theatre at Cˇ esk y´ Krumlov. Flying Machine (figs. 16 and 17) OTHER MACHINERY Elevators (figs. 6 and 14) Elevators are located under four sections of the sliding traps, three on SL and one on SR. The elevators rise between two vertical guides. Falling counterweights attached to the bottom of the elevators counterbalance the weight of the elevator platform and the object upon it to assist the stagehands. Typically, two stagehands are needed to operate each elevator. Wave Machine (fig. 15) PHOTO BY PAVEL SLAVKO When a sea scene was needed at Cˇ esk y´ Krumlov, it was located in the upstage area like that at Drottningholm.8 The wave machine consists of a rotating axle with several cross-arms with wheels at their ends. The device is covered with a cloth so when the axle is turned the cross-arms poke the cloth creating the illusion of a rolling sea.9 Several of these machines have been The upper gallery at Cˇ esk y´ Krumlov is much better organized than at many other extant eighteen century theatres and is similar to some seventeenth-century theatres. The area between the SR and SL side catwalks on the upper gallery consists of narrow walkways and a series of tracks (fig. 4). The flying machine is not rigged, but its operation is obvious. The machine consists of a rolling frame that runs along the tracks in the upper gallery. A large winch is mounted on the rolling frame for the lines supporting the seat for the flying performer. Two seats have survived, one for a single performer and one for two performers. Several flight patterns would be possible with this machine: a horizontal flight if the flying machine is simply pulled across the track, a vertical flight if the machine is stationary and the onboard winch is used to lower the performer, and a diagonal flight if the movement across the track is combined with rotating the onboard winch. Unfortunately the flying machine can no longer be used to Figure 10. Border Change Machinery Figure 9. Border Change Axle Figure 11.
