I can't find the right thing on the internet at the moment but my instructor has an English Longbowmans sword which for all intents and purposes looks exactly like a scimitar. Long, heavy, curved blade with a twisted crossguard to help protect the fingers. Its awkward and heavy (about triple the weight of the Gladius, if not more), difficult to wield but much like the scimitar was designed to be used by men with superior upper body strength that didn't want or expect to be in direct combat for very long at all. One swing and it should all be over, you really wouldn't want to be using this thing for very long at all.
The following pic is about the closest I can find but the twisted parts of the guard are longer in reality to protect fingers on one side (very important for a longbowman) and trap weapons with the other rather than the decorative appearance here
