The chlamys (Ancient Greek: χλαμύς, chlamýs, genitive: χλαμύδος, chlamydos) was a type of an ancient Greek cloak.[1] It was worn by men for military and hunting purposes during the Classical, Hellenistic and later periods.[2] By the time of the Byzantine Empire it was, although in a much larger form, part of the state costume of the emperor and high officials. It survived as such until at least the 12th century AD.
The ephaptis (Ancient Greek: ἐφαπτίς) was a similar garment, typically worn by infantrymen.[3]
