I'm not going to do an update on Amphipolis today. Maybe in a few days!
I'm working on another site and ... I've got to concentrate on that one for a little bit without getting distracted!
But yes the Caryatids are fabulous; they look like more archaising versions of the Tralles-Cherchel type I discussed the other day. That type is also known through Classicising copies at Mantua and other sites. None of the Tralles-Cherchel type have the raised arm preserved, and the Mantua-Venice variant figures the raised arm hold either a scroll or a mask ... So maybe the type didn't support the architrave after all! The backs of the Tralles and Cherchel types are very flattened, suggesting that the original backed onto a pillar. And the bitof the face found in the dirt supports the theory that it was structural damage.
Anyway, now I'll be dealing with Persian matter for a bit!
