Unappreciated art

Think of all the art not appreciated. Is it not the same for all the lives not appreciated? Are not artistic choices very similar to the moral choices we make in our lives? And though there seems not to be a provable universal set of rules, there are surely popular fads. Woe to the artists and lives not in fashion in their time and place. Is this not the reason that classics are discovered only after the death of their creators, as the themes of the time shift but the classic remains. Or because a fashion comes around capable of recognizing its brilliance. But surely we have forgotten, or never recognized some of the classics.
