Acinaces

The acinaces, also transliterated as akinakes (Greek ἀκῑνάκης) or akinaka (unattested Old Persian *akīnakah, Sogdian kynʼk) is a type of dagger or xiphos (short sword) used mainly in the first millennium BCE in the eastern Mediterranean Basin, especially by the Medes, Scythians, Persians and Caspians, then by the Greeks. The acinaces, of Scythian origin, but made famous by the Persians, rapidly spread throughout the ancient world. The Romans believed that this weapon originated with the Medes. The acinaces is typically 40–60 cm (16–24 in) in length and double-edged, and although there is no universal design, the guard may be lobed with the hilt resembling that of a bollock dagger, or the pommel may be split or of the "antenna" type. The scabbard – as much as anything else – defines the acinaces, and usually has a large decorative mount near the opening, allowing it to be suspended from a belt on the wearer's right side.
