Quite a primitive, barbaric flag, or so people say. Indeed, a shade of yellow with a pile of skulls, and that's it. The skulls represent the aggressive, warlike, and barbaric nature of the Gallios Barbarios. It is intended to scare enemies, and perhaps shows that the Gallios Barbarios were well aware of the fact that the true barbarians of Gallia laughed at them. Skulls represent barbarians, and the Gallios Barbarios were civilized barbarians. Or so they say, in truth, besides having villages and trade with Carthago, they waged many wars and had frequent battles about who the despot should be. The origin of the yellow and brown are unknown.
