The Macedonians wore a distinctive hat, the kausia () (Polybius IV 4,5; Eustathius 1398; Arrian, Anabasis of Alexander, VII 22; cf. Sturz, Macedonian Dialect, 41) from the Greek word for heat that separated them from the rest of the Greeks. That is why the Persians called them yauna takabara, which meant Greeks wearing the hat. The Macedonian hat was very distinctive from the hats of the other Greeks, but the Persians did not distinguished the Macedonians, because the Macedonian speech was also Greek (Hammond, The Macedonian State p. 13 cf. J.M. Balcer, Historia, 37 [1988] 7).
