I came across the following wonderful illustrations of backstage theatre from 1866. It’s all in French. I thought I could try translating it on my own, but no luck, so here it is in its untranslated glory. If any of my readers know French and would love to take a crack at it, let me know!
The staff, big and small things, a scenic study by Bertall.
The next few illustrations show some manual sound effects and props.
