OK, anorak time.

“Picts” is not “Celtic for painted” but Latin. Picti/pictus = painted, decorated, etc. That’s where “picture” comes from.

There were other sources for blue colouring besides woad and indigo.

Here in the Med ta’ missirijietna, we had murex. It was extremely labour-intensive and therefore very expensive. Hence royal purple.

From further east in Central Asia came lapis lazuli. Uber duper expensive.

Hence the rarity of blue in European painting from the middle ages right up to the 19th century. When synthetic blue dyes were invented, the price of blue pigment finally became affordable, and that’s when Impressionism could take off. It was the equivalent of digital cameras after wet film.

The essential information for julob is that so-called Celtic culture only survived in Scotland in the extreme north-west and the Western Isles. William Wallace would have spoken, fought, dressed and behaved like an Anglo-Norman. That whole bagpipes and kilt thing was a clever policy by the British, post-Culloden, to forge national unity. It worked.

I’m sorry, but where does Braveheart come into it?

Oh, I see! You mean Mel Gibson playing William Wallace with his face painted with woad.
