As I noted in the introduction to my novel Night of the Furies, the dark voyage of Homer's hero is known as the Nekyia, the 'night sea journey.' The Swiss psychologist Carl Jung saw the Nekyia symbolically as a journey into the unconcious--the source of the creative and instinctual forces of life.
Mythologically, the night sea journey motif usually involves being swallowed by a dragon or sea monster. It is also represented by
imprisonment or crucifixion, dismemberment or abduction, experiences traditionally weathered by sun-gods and heroes: Gilgamesh, Osiris, Christ, Dante, Odysseus, Aeneas. In the language of the mystics it is the dark night of the soul.
All the night sea journey myths derive from the perceived behavior of the sun, which, in Jung's lyrical image, "sails over the sea like an immortal god who every evening is immersed in the maternal waters and is born anew in the morning. ["Symbols of the Mother and of Rebirth,"CW 5, par. 306.] The sun going down, analogous to the loss of energy in a depression, is the necessary prelude to rebirth. Cleansed in the healing waters (the unconscious), the sun (ego-consciousness) lives again. (NYAAP)
I perceive something in the collective soul of man which from time to time secretly needs the catharsis of economic collapse or war, or even both of those grievous things. And I also perceive that, as that secret need grows in the soul, so is it ineluctably met.
...One way or another we get the cathartic catastrophe, the ruthless purge of the shallow motives and inducements we had grown habituated to responding to, and their replacement by certain profounder, more basic incentives: staying alive, fending for those we love, and maybe fighting and even dying for a cause or a country and the half-forgotten principles that define it.
Being forced to face the looming abyss leads to a kind of deepening, a profound reconnection with fundamental truths. Hell may be the very thing we needed all along.
