Grasshopper Weathervane, 1840-1875

Weathervanes point into the direction of the wind. This helped viewers anticipate weather changes before local forecasts became common after 1920. Functional weathervanes required a basic pointing device and directional arms, but manufacturers added decorative elements, or ornaments, to appeal to consumer interests. Before they were mass-produced as symbols of commerce, grasshopper weathervanes appeared atop London's Royal Exchange and Boston's Faneuil Hall.
