Whither the tradition of the solitary floorlamp on an otherwise dark stage?

Would someone please be so kind as to point me toward a discussion of the tradition of leaving a lighted floorlamp on the stage of otherwise unoccupied/inactive theatres? Google has been uncharacteristically unhelpful in my quest.

One of the many Theatrical Traditions - keeps the ghosts company apparantly.

Also, the house and stage are a big place. That little light helps you see what’s going on in there–be it a ghost, a burgler, a stray raccoon, or that chair in front of you. ouch

Thanks. It just seems to be such a universal practice, I wondered if there might be some interesting story in how it got started. Stages typically have a myriad of lights that COULD be used for this purpose, and yet the (typically) battered floor lamp is generally employed for the task.

It is generally a requirement for safety purposes.

Interestingly, according to union rules in professional theaters, it is the only light that can be touched and operated in the stage area by somebody other than the lighting designer and his/her crew. Usually it’s placed and activated by the stage manager or a designee.

Since I’m procrastinating, other people have to suffer as well.

“Whither” means to where. It’s whence that means from where.

I squat corrected, thank you. :o
