recently sold for 6,000 Euros by a Belgian antiquities dealer. If it is real it is an amazing thing, one of less than a dozen clear representations of the Celtic horned god.
this web site, which discusses six depictions of Cernunnos, only one of which (the one from the Gundestrup Cauldron, above) is as good as the one I am wondering about.
Plus, it was sold on EBay. Plus, the seller is named Nazzi. Ok, that wasn't fair. But EBay – is that where we would expect to see a major historical artifact, a crucial piece of evidence for ancient paganism? The only provenance given at the seller's web site is "ex private collection." It seems to me that if this were real, national museums would bid hundreds of thousands for it.
Until I see more, I'm leaving it out of my lectures.
