The horns, the most metal of hand gestures, have a tangled history. In Buddhism they represent the expulsion of demons, while in certain Latin countries they signify something far ruder.
In simple metal terms, they are a joyous symbol of unity, exaltation and, well, general rock-ness rather than anything more sinister. And, as we all know, Ronnie James Dio played a huge role in popularising the thumbs-in-palm-out hand-flash. But did he invent the gesture? He didn’t think so.
“I doubt very much if I would be the first one who ever did that. That's like saying I invented the wheel. I think you'd have to say that I made it fashionable,” said the former Rainbow and Black Sabbath singer prior to his death in May 2010.
