You could call them the “Clay Ladies,” as our coven kid Robin did.
They exist in their tens—if not hundreds—of thousands across the world.
Goddesses? Fertility magic? Who can say?
Clearly, they're symbolic. Clearly, they're meaningful. We shouldn't expect that they meant the same thing to every culture that made (and makes) them. But to claim that they have no religious significance (as some academics have done) seems to me to fly in the face of general human experience. And if (incredibly) they never did before: well, they certainly do now.
And sometimes, I think, we can also say: this much, at least.
