Rope

A rope, also called a painter when used on a boat, (AUDIO: Dead London) was an object used to tie other objects or people down.

In August 79, the Sibylline Sisterhood tied Donna Noble down with ropes before trying to murder her, but the Tenth Doctor freed Donna with his sonic screwdriver. (TV: The Fires of Pompeii)

The funambulist Spring-heeled Sophie made a living by walking across a tightrope. (AUDIO: Dead London)
