Association of the Week: The Key

The key symbolizes not only the power to open and to close, but also the power to “tie and untie” those that carry it.

In Christian iconography, Peter, the apostle, carries the keys of heaven that Christ gave him. Also, in the Apocalypse it is said that a great key is used in order to lock the devil for a thousand years in the abyss.
The tongue is also said to be the key of the mouth: enabling one not to pronounce ill thoughts. In cities, the presence of keys in their flags alludes to the sovereignty of the place.

Now you take the floor: what do you associate with the key?
