Faneuil Hall & the Test of the Gilded Grasshopper (View X2)
Faneuil Hall, located near the waterfront and today's Government Center, in Boston, Massachusetts, has been a marketplace and a meeting hall since 1742. It was the site of several speeches by Samuel Adams, James Otis, and others encouraging independence from Great Britain, and is now part of Boston National Historical Park and a well known stop on the Freedom Trail. It is sometimes referred to as "the Cradle of Liberty".
The gilded grasshopper weather vane on top of the building was created by silversmith Shem Drowne in 1742. Gilded with gold leaf the copper weather vane weighs eighty pounds and is four feet long.
Knowledge of the grasshopper was used as a test to determine if people were spies during the Revolution period. The people would ask suspected spies the identity of the object on the top of Faneuil Hall; if they answered correctly, then they were free; if not, they were convicted as British spies. (Wikipedia)
