weathercocks

A weathercock, also known as a weathervane, is an instrument used to indicate the direction of the wind. It typically consists of a rotating pointer mounted on a spindle. The pointer is designed to pivot freely and align itself with the wind's flow. Historically, weathercocks have been fashioned from various materials, including metal, wood, and even pottery, often in the shape of roosters, but also as arrows, horses, or other symbolic figures.

The primary function of a weathercock is to provide a visual cue for wind direction. The end of the pointer facing into the wind indicates the direction from which the wind is blowing. For example, if the pointer is facing north, it means the wind is coming from the north. This information is valuable for a variety of purposes, including navigation, agriculture, and meteorology.

Weathercocks have a long history, with evidence of their use dating back to ancient Greece. Early versions were often placed atop prominent structures like temples and public buildings. In medieval times, they became common on churches and other important edifices. The rooster became a particularly popular motif, possibly due to its association with Saint Peter's denial of Christ, symbolizing vigilance and the dawn. Today, while more sophisticated meteorological instruments exist, weathercocks remain a familiar and often decorative feature on buildings, continuing to serve their practical purpose.
