Views of the Gallic enemies of Rome have varied widely. Some older histories consider them to be backward savages, ruthlessly destroying the civilization and "grandeur that was Rome". Some modernist views see them in a proto-nationalist light, ancient freedom fighters resisting the iron boot of empire. Often their bravery is celebrated as worthy adversaries of Rome. See the Dying Gaul for an example. The Gallic opposition was also composed of a large number of different peoples and tribes, geographically ranging from the mountains of Switzerland to the lowlands of France and thus are not easy to categorize. The term Gaul has also been used interchangeably to describe Celtic peoples farther afield in Britain adding even more to the diversity of peoples lumped together under this name. From a military standpoint, however, they seem to have shared certain general characteristics: tribal polities with a relatively small and lesser elaborated state structure, light weaponry, fairly unsophisticated tactics and organization, a high degree of mobility, and inability to sustain combat power in their field forces over a lengthy period. Roman sources reflect on the prejudices of their times, but nevertheless testify to the Gauls' fierceness and bravery.
The current paradigm presents the following concepts: (a) infectious agents are enemies that should be destroyed; (b) the function of the immune system is to destroy the infectious agents and to maintain the organism free of them; (c) genomes of the host and the infectious agents are closed structures without relationship among them; (d) the vaccines should maintain the organism free from infectious agents; (e) theoretical base: attrition and destruction.
Now, the reason why those ancient writers treated this subjectonly by types and figures was because they durst not make openattacks against a party so potent and so terrible as the criticsof those ages were, whose very voice was so dreadful that alegion of authors would tremble and drop their pens at thesound. For so Herodotus tells us expressly in another placehow a vast army of Scythians was put to flight in a panic terrorby the braying of an ass. From hence it is conjectured bycertain profound philologers, that the great awe and reverencepaid to a true critic by the writers of Britain have been derivedto us from those our Scythian ancestors. In short, thisdread was so universal, that in process of time those authors whohad a mind to publish their sentiments more freely in describingthe true critics of their several ages, were forced to leave offthe use of the former hieroglyph as too nearly approaching theprototype, and invented other terms instead thereof that weremore cautious and mystical. So Diodorus, speaking to thesame purpose, ventures no farther than to say that in themountains of Helicon there grows a certain weed which bears aflower of so damned a scent as to poison those who offer to smellit. Lucretius gives exactly the same relation.
