Xyston

The xyston ( "spear, javelin; pointed or spiked stick, goad), was a type of a long thrusting spear in ancient Greece. It measured about long and was probably held by the cavalryman with both hands. It had a wooden shaft and a spear-point at both ends. Possible reasons for the secondary spear-tip were that it acted partly as a counterweight and also served as a backup in case the xyston was broken in action. The xyston is usually mentioned in context with the hetairoi (), the cavalry forces of ancient Macedon. After Alexander the Great's death, the hetairoi were named xystophoroi (, "spear-bearers") because of their use of the xyston lance. In his Greek-written Bellum Judaicum, the Jewish historian Flavius Josephus uses the term xyston to describe the Roman throwing javelin, the pilum.

The xyston was wielded either underarm or overarm, presumably as a matter of personal preference. It was also known, especially later, as the kontos; meaning literally "barge-pole"; the name possibly originated as a slang term for the weapon.
