AnthonyL said:What we have of Gauls, archaeologically, does paint a picture. Not clear, but not too blurry. If one examines Gallic archaeology, including that of southern Britain (composed of mainly more Gauls and Belgae), we find a very sophisticated, advanced society. Regular chronicle writing would be a huge boon, but it is not culture or civilization itself. We find well-ordered, designed, planned cities, built to sustain a thriving, advanced community. They were far from savage 'fantasy'-styled barbarians, based on the archaeology alone, let alone when we take into account critical reading of historical texts that describe them (even those who had an apparent distaste for Gauls let slip some of their better features, and much of what was written was either grains of ignorance or propaganda mixed with grains of the truth; it's a lot of sifting to find who people really were if you base it on those who wrote about them, but weren't part of them).
Gauls had, reiterating, a rather advanced society and sense of technology, given the period. Preserved skulls in northern modern France show evidence of successful cranial surgery (scars healed over near the top of the skull, or sides, where brain surgery would have occured, and then the skull fragment removed replaced with the original piece, apparently santized well-enough to not infect and kill the person, so it grew back together). Mind, this doesn't just tell us these people performed successful brain surgery (itself remarkable), it also says they must've understood anasthesia, if we take into account other scar tissue and such; even with modern surgical method, without anesthetics, people would die from shock from the pain in huge numbers. Do mind, anesthetics were used in the middle ages, but declined in the Renaissance, as they were thought to increase the chance of dying, much as bathing began to drop off then (the idea of a savage, filthy medieval Europe is itself a bit of pop history that doesn't stand to scrutiny of both records and archaeology, but they also gave us much better historical records we still research to these days to find who they were).
The idea of Gauls as savages with no sense of science (as some writers called them in their own day) is smashed by archaeology. We find truly remarkable, Celtic works, of scientific ingenuity. Philosophy, it was widely argued if Pythagoras had given Celts certain ideas about philosophy and math, or if he had adopted from them those ideas, as both occured in Pythagorian thought, and reported Celtic thought. Either way it'd imply a thriving philosophical community; either interested in finding new ideas, or developing and spreading their own, or a bit of both. Defining culture by writing alone (which Gauls had, but we're not certain of extent, as mentioned) cannot account for the truly intricate nature of a society, or how developed it is. We know Gauls, and Celts in general, had a very advanced view of certain forms of mathematics, developed military philosophy (adopted in part by both Greeks and Romans; the Hellenic theuros was brought by Gauls, after all, and some of their soldiers seem to imitate Celtic fighting, and their command structure was, partly, adopted by Romans, who mixed it with Hellenic structure).
Really, I'd view the main Roman advantage, particularly militarily, as a good sense of syncretism. The ability to take ideas, and combine them into something using benefits of both.
I'm wholly ignorant of this thriving Gaullic community of philosophers or at least proto-philosophes. Do you have a link where one could be thusly edified?
