Transportation
About this time or shortly afterward an unknown shipbuilder, probably a Phoenician, starts building ships with one or two banks of oars with each oar propelled by multiple rowers. Historians believe that the name of the type of ship became based on the number of rowers per oar multiplied by the number of banks. Thus, a quadrireme instead of having four banks of oars, each with a single rower, might have one bank with four files of rowers or two banks with two rowers per oar. Because of the length of the oars required, each rower must stand and fall back with each stroke; this provides additional power. See also 399 bce Transportation.
