KENNEDYVILLE — A weathervane, also known as a wind vane because it is used for indicating wind direction, is one of the oldest meteorological instruments.

It’s mounted on a shaft or spire that is elevated off the ground. The wind catches the rudder blade and makes it rotate. The narrow end of the vane points into the wind and tells you the direction the wind is coming from.

This means, for example, that if the wind is coming from the west, the arrow will point to the west. This would mean that if you were to face west, you would feel wind on your face.

Weathervanes have been used since ancient times and have graced the steeples of grand cathedrals and the roofs of the most rustic barns.
