W. B. Yeats, "Mad as the Mist and Snow"

Bolt and bar the shutter,
For the foul winds blow:
Our minds are at their best this night,
And I seem to know
That everything outside us is
Mad as the mist and snow.

Horace there by Homer stands,
Plato stands below,
And here is Tully's open page.
How many years ago
Were you and I unlettered lads
Mad as the mist and snow?

You ask what makes me sigh, old friend,
What makes me shudder so?
I shudder and I sigh to think
That even Cicero
And many-minded Homer were
Mad as the mist and snow

--W. B. Yeats, "Mad as the Mist and Snow"

William Styron, Excerpt from "Darkness Visible"

Since antiquity--in the tortured lament of Job, in the choruses of Sophocles and Aeschylus--chroniclers of the human spirit have been wrestling with a vocabulary that might give proper expression to the desolation of melancholia. Through the course of literature and art the theme of depression has run like a durable thread of woe--from Hamlet's soliloquy to the verses of Emily Dickinson and Gerard Manley Hopkins, from John Donne to Hawthorne and Dostoevsky and Poe, Camus and Conrad and Virginia Woolf. In many of Albrecht Dürer's engravings there are harrowing depictions of his own melancholia; the manic wheeling stars of Van Gogh are the precursors of the artist's plunge into dementia and the extinction of self. It is a suffering that often tinges the music of Beethoven, of Schumann and Mahler, and permeates the darker cantatas of Bach. The vast metaphor which most faithfully represents this fathomless ordeal, how ever, is that of Dante, and his all-too-familiar lines still arrest the imagination with their augury of the unknowable, the black struggle to come:

Nel mezzo del cam ming di nostra vita Mi ritrovat per una sel va
oscura, Che la diritta via era smamta.

In the middle of the journey of our life I found myself in a dark wood,
For I had lost the right path.

One can be sure that these words have been more than once employed to conjure the ravages of melancholia, but their somber foreboding has often overshadowed the last lines of the best-known part of that poem, with their evocation of hope. To most of those who have experienced it, the horror of depression is so overwhelming as to be quite beyond expression, hence the frustrated sense of inadequacy found in the work of even the greatest artists. But in science and art the search will doubtless go on for a clear representation of its meaning, which sometimes, for those who have known it, is a simulacrum of all the evil of our world: of our everyday discord and chaos, our irrationality, warfare and crime, torture and violence, our impulse toward death and our flight from it held in the intolerable equipoise of history. If our lives had no other configuration but this, we should want, and perhaps deserve, to perish; if depression had no termination, then suicide would, indeed, be the only remedy. But one need not sound the false or inspirational note to stress the truth that depression is not the soul's annihilation; men and women who have recovered from the disease--and they are countless--bear witness to what is probably its only saving grace: it is conquerable.

For those who have dwelt in depression's dark wood, and known its inexplicable agony, their return from the abyss is not unlike the ascent of the poet, trudging upward and upward out of hell's black depths and at last emerging into what he saw as "the shining world." There, whoever has been restored to health has almost always been restored to the capacity for serenity and joy, and this may be indemnity enough for having endured the despair beyond despair.
