Barry Fell noted that this particular image from the Gundestrup Cauldron is holding up his hands and spelling "thunder" in Ogham -- and the figure is a thunder deity. One view (which IMHO is correct) is that the method of writing began as fingerspelling, a way to communicate silently and (if others were unfamiliar with it) secretly.
His hands are up, but something tells me he is NOT surrendering.
Or maybe he was saying, “Hands up! Don’t shoot!”
“is that the method of writing began as fingerspelling, a way to communicate silently and (if others were unfamiliar with it) secretly.”
Fascinating. And now the gangsters, outside the pale of civilization by their own choice, are re-inventing it.
