I shall mark the day by relating my favourite anecdote of the French Revolution. It concerns the fate of one notable aristocratic intellectual during the Terror and is from Simon Schama's Citizens:
The great exponent of a state in which science and virtue would be mutually reinforcing, the Marquis de Condorcet, died in abject defeat, escaping from house arrest in Paris in May 1794 and walking all the way to Clamart only to arouse suspicion at an inn when he ordered an omelette. "How many eggs?" asked the patronne. "Twelve," replied Condorcet, suggesting a damaging unfamiliarity with the cuisine of the common man. He was locked up for the Revolutionary Tribunal but was found dead in his cell before he could be transported to Paris.
Now that really is irony. Extra helpings, in fact.
By the way, I've plugged it before somewhere but I recommend Hilary Mantel's novel about the French Revolution 'A Place of Greater Safety'. It's fascinating, accomplished, stylish, educative, epic and credible. I wonder why it isn't a film yet?
