Ooo, they look interesting.
One site said maybe thick liquid or powder from the hole spoon into the cross spoon and then the shapes could be interpreted in the context of the four quarters to denote time, moon phases or stages of life.
I think it’s as good an idea of what they were as any (unless they’re making absinthe, which I doubt *grin*). To me, with divination, I genuinely think one could use anything if it works for you. So to me, it doesn’t matter if that’s what they were ‘really’ for – we’ll likely never know – but if it helps someone tap in, then go for it. I find this stuff endlessly fascinating, so thanks for that.
