Ballista
/bəˈlɪstə/noun
An ancient siege engine that shot bolts or stones using twisted cords for power.
The Greek roots
Literally: “thrower”
The story of the word
βάλλω may be the most productive verb in the language. A thing thrown alongside is a παραβολή, giving parable and parabola; a thing thrown in your path is a πρόβλημα; a token thrown together to match its other half is a σύμβολον; and the one who throws accusations across, ὁ διάβολος, is the devil. Roman engineers took the noun for a torsion engine that drove a bolt down a groove, powered by skeins of twisted sinew rather than a bent bow.
