Julian Cope, ex-frontman of The Teardrop Explodes, the 1980's rock/indie band, has a piece in The Guardian. From the world of rock, and going slightly off the rails for a period, he went on to write a very unusual, but well regarded book, on pre-modern history, The Modern Antiquarian. He seems to have an abiding interest in archaeological and historical investigation, so a kindred soul perhaps.
In the newspaper, he has had a preview of the forthcoming show at the British Museum, The Celts: Art and Identity, Cope is at pains to mention how wide the curators might have drawn the Celtic identity line, but it's been stretched widely for a very long time now. It's really just a label for anything pre-Roman almost. However, it has still strong connotations when identity comes to the fore, especially of the national variety.
I'm looking forward to the show.
