Whilst I was wandering round Paris on Saturday morning I found a shop of antique curiosities in the Rue Dante. It was shut (aren't they always?) but in the window was a bell jar over some kind of glove. On closer inspection it turned out not to be a glove but a hollow filigree hand made entirely of what looked like lichenous threads, or possibly the kind of thing left attached to a wall when you pull ivy away. I've got a rather poor photo on my phone but it doesn't do it justice.
I'm not sure what the point of it was, perhaps there was none but it sounds like the kind of thing some magician might use.
