The ancient Greeks would likely disagree with that sentiment. Consider an incident recounted by the Greek historian Herodotus, where a guy named Aristagoras tried to convince the Spartans to go to war with the Persians to drive them out of Ionia. As part of his spiel, he essentially claims that the Persians will be lightweights. From Book 5 Chapter 49 I quote: “They wear trousers when they go into battle, and funny caps on their heads. So you can see how easy they will be to beat!” While modern observers may take issue with the first claim, both sides can agree that the Smurf hats the Persians wore are kind of silly looking (for reference, check out the Film Crew feature Giant of Marathon).
