My all-time favorite comics, in both French and English, are the Asterix books by Goscinny and Uderzo. The intro is always the same:
We are in the year 50 before Jesus Christ. All Gaul is occupied by the Romans . . . All? No! One village inhabited by indomitable Gauls still resists the invaders. And life is not easy for the garrisons of Roman legionnaries camped in Babaorum, Aquarium, Laudanum and Petitbonum . . .
Now a team of French archaeologists may have unearthed evidence of a Gallic "holdout" culture that lasted well into the 3rd century AD:
A macabre 1,700-year-old mass grave of people and horses,
discovered in Normandy, poses perplexing new questions about the Roman
conquest of France. Was there a small part of ancient Gaul which
refused, Asterix-like, to surrender for 300 years?
The grave site, from the 3rd century, which was discovered by French
state archaeologists at Evreux, appears to contain ritual arrangements
of human and horse remains. In one, a human skull is clasped between
two horse's skulls, like the two halves of a giant shell.
In Gaullish times, 300 years earlier, graves containing both horses
and people were common. No such grave has ever been found from the
Roman period, and even in the previous era, the remains were kept
carefully apart.
In the recently discovered grave, about 50 miles west of Paris, the
bones appear to have been intentionally mixed. The skeletons of 40
people and 100 horses have been found so far.
Was this a local - or maybe more widespread - survival of the
Gaullish cult of Epona, the goddess of horses and warriors?
Maybe, maybe not, but I believe the site map looks a little like this:
