Terrakota Statue eines Makedoniers 3 Jhdt v Chr.jpg
colspan=2|Two 4th and 3rd century BC terracotta statues from Athens depicting ancient Macedonians wearing the kausia.
The kausia was an ancient Macedonian flat hat.
It was worn during the Hellenistic period but perhaps even before the time of Alexander the Great and was later used as a protection against the sun by the poorer classes in Rome.
Depictions of the kausia can be found on a variety of coins and statues found from the Mediterranean to the Greco-Bactrian kingdom and the Indo-Greeks in northwestern India. The Persians referred to the Macedonians as Yaunã Takabara or "Greeks with hats that look like shields", possibly referring to the Macedonian kausia hat.
A modern descendant of the hat may be the Pakol, or 'Chitrali cap': the familiar, and remarkably similar, men's hat from the mountains of Afghanistan and Northern Pakistan.
