Analysis of information sources in references of the Wikipedia article "Murmillo" in English language version.
During the first century BC [...] Samnites and at any rate those Gauls inhabiting Italy [...] were part of the process of Italian integration. By the time of Augustus, it had become inappropriate for them to be perceived as outsiders; and the Samnis turns into a secutor, while the Gallus becomes a murmillo.
Whereas the Thracian helmet was provided with a crest, that of the Murmillo had a very large three-dimensional dorsal fin, presumably to represent a fish [...]. [...] Another example [...] is more elaborate, [...] decorated with an all-over silver-and-gold two-toned pattern to give the appearance from a distance of shimmering fish scales [...].
The murmillo acquired his name from the type of helmet he wore: a Gallic helmet with a fish-shaped crest.
