From the first article:

Dr Fraser Hunter, a leading authority on carnyces from the National Museums of Scotland says, “this extraordinary find will add enormously to our understanding of the Iron Age world.

“I’ve looked at carnyces from around Europe, and the full research and conservation of these incredibly fragile remains will reshape our view of sound and music in the Iron Age.

“The carnyces and the boar-headed standard are styles well known on the continent and remind us that communities in Britain were well-connected to a wider European world at this time.”

A possible symbol to use if the UK ever reconnects with the wider European world. :)
