|Based on Roman centurion helmet.|
|Greek style helmet.|
The crest on ancient Greek and Roman helmets serves as such a sign of authority and create an intimidating image. It occurs to me that the shape of the crest is similar to a ram's horn, albeit a flattened version.
Before the bronze age, plates of horn material were probably used as armor to deflect or cushion blows. Is it also possible that the crest shape devolved from helmets made of horn?
