At Holyroodhouse, one picture captures the crushing defeat of Bonnie Prince Charlie's Highland soldiers.
Perhaps it's just as well the picture's not so easy to get a good look at.
It's a piece of propaganda.
It shows the government troops clearly with the upper hand,
well dressed,
well armed
and then the supporters of Bonnie Prince Charlie,
exhausted, starving.
They looked like a rabble
and certainly they were no match for the government troops.
Culloden was a blood-soaked massacre.
When the battle was over,
the blood lust was running so high among the victors
they went on to slaughter men, women and children unfortunate enough to be living near by.
Charles escaped to France,
but he never got over his failure to take the British crown.
In Scotland,
the authorities cracked down on his rebel supporters.
Highlanders could no longer wear tartan,
now a crime against the state.
Almost 60 years passed
before they could sport it again.
