Noun
sarissa (plural sarissas or sarissae)
(Ancient Greece) A long pike used in the traditional Greek phalanx formation.
According to Plutarch, sarissas of 5 meters seemed light and handy after a very long training, but a 7,5 meters sarissa, no matter how intensively prepared were the soldiers, could never be wielded with ease. Source: Internet
Before a battle the sarissa were carried in two pieces and then slid together when they were being used. Source: Internet
The Macedonian phalanx was better trained and armed with the sarissa enabling it to outreach its competitors and stave off enemy cavalry. Source: Internet
