It's a very heavy metal disc, probably cast iron, with the directions marked on it. It's probably meant to go out in a garden, and maybe one day I'll have a garden of my own to put it in, but for now it's lying in the middle of my altar as an additional elemental alignment.
Then there was this small plate. Made in Scotland, it carries a 6-9th century Celtic knot pattern on it. I've tried researching the manufacturer a bit (St. Andrew's?), but so far I have been unable to find additional information on it. That being said, it's a lovely little dish, and in very good condition.
I love auctions - they're a great place to find unique witchy stuff at good prices!
