...I've also stumbled across an old edition of Agrippa (ed Willis Whitehead) which has a very interesting story about Reuchlin casting a circle in a pub to shut everyone up so he could finish reading his book in peace.
There is also a very curious chapter on using black mirrors, and "as soon as any Mystic is known to be doing this he is visited by members of the Brotherhood and necessary data secured".
Ahh - yessssssss. There are many times in the course of "feeling slappy" - when I wish I could mute people in such a way. *twinkles*
The Brotherhood? Black mirrors? (looks quickly out window and decides she's safe).
I have an oval Obsidian mirror, 5 inches in diameter (apparently hand polished by the man who sold it to me at the market in Coven Garden. His name was 'Tony Fossils').
And a pocket Obsidian mirror 2 inches.
Alas! - I am rubbish at scrying...
