What is a Weathervane?

A weathervane is a device that is used to indicate the direction of the wind. It typically consists of a pointed object, such as an arrow or rooster, mounted on a horizontal axis that is supported by a vertical rod. The axis is mounted in such a way that it can rotate freely, and the pointed object is designed to align itself with the wind direction. This allows the weathervane to function as a simple anemometer, providing a visual indication of the wind direction and speed.

Weathervanes are often mounted on rooftops or other high points, such as the top of a church steeple or the mast of a boat, where they are exposed to the wind. They are also often decorative, with intricate designs and ornate embellishments. Some weathervanes are even considered works of art, with collectors seeking out rare and unusual examples.

In addition to their practical use as a wind indicator, weathervanes are also popular as a form of folk art and as a symbol of regional or cultural identity. Many weathervanes feature iconic figures or symbols that are associated with a particular place or group, such as a rooster for France or a lobster for Maine.
