That first pic HAS to be staged. No way an item can lay on the bottom of a river for 1800 years and not be covered with silt.

Yes, I think you’re right. Matter of fact, that looks more like an aquarium tank with a diver in it than the Rhine. But it’s still surprising these objects look so fresh.

I was wondering about that. But if the river bottom was scoured by higher flow once in while, then the heavy metal objects would accumulate in piles.

It's also possible hat the photo was taken after a water jet was used to excavate.

In any case, the items found are amazing, including the bronze head of a horse cut from a sculpture.
