Looking at [this statue, The Dying Gaul (slightly nsfw)] (https://upload.wikimedia.org/wikipedia/commons/d/d4/Dying_gaul.jpg) seems to indicate that this was how Gauls were commonly portrayed and stereotyped as looking before the shift from BC to AD. This statue is said to be a copy of an original from the Hellenistic Era, and this got me also wondering whether or not perceptions of Gauls had changed at all during those centuries. What does the ancient literature say? Does it differ from century to century and era to era, or is it constant in describing what Gallic people looked like?
