There is a name for miracles involving headless people who continue to exist. They are called "cephalophores".
The patron saint of France is not the teenage upstart, St Joan of Arc, as many people believe. He is Saint Denis, the most famous cephalophore in all of history.
He was Bishop of Paris around 250 CE, when the Romans were executing Christians in a serious purge. The general consensus was that Christians were atheists, as they did not believe and would not swear loyalty to the Roman gods (Jupiter, et al) and this had pissed off all the homies on Mt Olympus, who then caused grief and woe for the Romans, as the empire was by then in a state of decline.
They chopped off Denis' head, but he picked it up and marched all the way up the highest hill before finally expiring at the summit. This is a distance of 10 kms, or over 6 miles, and they claim that St Denis was preaching the entire way, with his head held against his chest.
The best we have managed seems to have been Mike, the headless chicken. We seem to be relatively unimpressed by a headless chicken, perhaps because miracles just don't go with chickens. As human beings go, chickens are easily the greatest blessing in the bird world. We do not appreciate them enough.
We just don't get any cephalapore miracles anymore. You would think that we would, with all the beheadings that have happened since 250 CE, but, sadly, no. I imagine such a miracle as Saint Denis would easily go viral on youtube.
This hill is Montemarte, or Mount of the Martyr and St Denis is the martyr for whom this area is now named. Most of Paris s flat, so if you want to have a good view of the whole city from your hotel, book a room in Montmarte.
Saint-Denis is where the English name "Sidney" comes from. It is NOT a woman's name, no matter what OJ Simpson thought.
The English also pronounce St John as "Sinjin", and use it as a man's name. Americans generally are unaware of this, I have noted.
