Navigation is a field of study that focuses on the process of monitoring and controlling the movement of a craft or vehicle from one place to another. The field of navigation includes four general categories: land navigation, marine navigation, aeronautic navigation, and space navigation.
And that all seas are made calme and still with oile; and therefore the Divers under the water doe spirt and sprinkle it aboard with their mouthes because it dulceth and allaieth the unpleasant nature thereof, and carrieth a light with it.
Pliny the Elder, Natural History, Book II, Chapter CIII. Holland's translation.
