The Ancient Time
a: The odometer ~
b: a wheel mounted on a wheelbarrow
What: "The Roman architect and engineer, Vitruvius, invented
the first odometer in history. The odometer is like a wheel
mounted on a wheelbarrow and when pushed along the
ground by hand it automatically dropped a pebble into
a container at each revolution, giving a measure of the
distance it travelled. It is now essential in cars today,
measuring the distance the vehicle travels."
