What does quadrireme mean?
A quadrireme is an ancient Greek or Roman warship built with four banks of oars, usually arranged in tiers along the vessel's length. These ships were among the largest and most formidable oared vessels of classical antiquity, with large crews of oarsmen providing both speed and manoeuvrability. The term is now mainly historical or archaeological, used when discussing ancient naval warfare, ship construction, or the remains of sunken vessels. It should not be confused with a bireme or trireme, which have two and three banks of oars respectively. The word is memorable because it describes a striking feat of ancient engineering: a human-powered fighting vessel whose power depended on the coordinated work of hundreds of oarsmen.

Where does quadrireme come from?
The English word comes through Latin from quadriremis, meaning “having four banks of oars.” Its elements are quattuor, “four,” and remus, “oar,” the same Latin root that gives related forms such as bireme and trireme. The form reflects the vessel's distinctive four-tiered arrangement of oars.
