A year ago I realized that (at least to me) these Greek theater masks perfectly symbolize my husband's bipolar disorder.
There are at least two sides to him that for the past 3+ years have 'masked' the person we used to know and the person I fell in love with. There is his manic side which is overly energetic, high flying, there's no limit but the sky person. And then there is the extremely depressed, the world is out to get me person. Not to mention the mixed episodes when he is full of energy but too depressed to do anything. While all of those are now part of him it is easier for me to deal with his illness when I tell myself that the 'old' him is just hiding behind one of these masks and is fighting to come back out to be with me. The 'performance' might take an hour, a week or a month but he is there, waiting to rejoin me.
