If I had just discovered major depressive disorder in the 5th Century BC I think I would have ended up calling it ‘Melancholic Obtenebrous Dipolar Compression of the Spirit’ (MODCoS). While Melancholy is a good description of the every day world wearyness that one can experience with ‘general’ depression and is probably best summed up by Dürer’s engraving, entitled ‘Melencolia I‘ :
That’s ‘Melancholic’, what about ‘Obtenebrous Dipolar Compression of the Spirit’ ?
Tenebrous is simply shadowy, gloomy or dark. Obtenebration is the act of darkening, so by inference Obtenebrous is the adjective of darkening, a thinning similar to what the Hobbit, Bilbo says ;’like butter spread over too much bread’.
Dipolar – not bipolar as in ‘both’ or ‘twice’ (bi-) but di- (both) because when one is Melancholic and Obtenebrated one is almost entirely a different person. You can do (and say) things that you would otherwise never conceive of. You have a different frame of logic, which to the dipolar you is *perfectly* rational.
Compression of the Spirit – basically the Black Vise that I described before.
