The word "mask" appeared in English in the 1530s, from Middle French masque "covering to hide or guard the face", derived in turn from Italian maschera, from Medieval Latin masca "mask, specter, nightmare".
Masks. We all wear them. The work face. The face you put on when visiting family. The out in public face. But what about putting on a different mask to accentuate who you really are or want to be?
