Charm

CHARM, n. a something pleasing in a person or thing; it came in with the Revolution and went out with the War. 

Whether people swear on the old altar, before the Holy Sacrament, or take the oath before the cold image of abstract liberty, the true symbol is elsewhere. The beauty, the grandeur, the eternal CHARM of those festivals, is that the symbol is a living one.

Michelet, History of the French Revolution.
