Description

Word of Greek origin meaning "road measurement." The instrument is used to measure the distance travelled by a vehicle. Described by Vitruvius in De architectura (1st C. B.C.E.) and later by Hero of Alexandria (1st C. C.E.). In the Renaissance, different types of odometers were designed by Leon Battista Alberti (1404-1472) and Leonardo da Vinci (1452-1519), among others. The device onsists of a revolution counter attached to a wheel dragged by hand or fastened to a horse or vehicle. The distance travelled was obtained by multiplying the circumference of the wheel by the number of revolutions.
