"O brothers, who through a hundred thousand perils have reached the west, to this so brief vigil of the senses that remains to us, choose not to deny experience, in the sun's track, of the unpeople world." Dante, Inferno, Canto XXVI.
The character speaking is Ulysses who, according to Dante's extension of the ancient myth, was not satisfied with life at home with Penelope and his family, and set forth once more with his aged shipmates to explore beyond the pillars of Hercules (Straits of Gibraltar). Reaching the Antipodes, they spied Mount Purgatory rising into the clouds, but were swamped and drowned by a sudden storm.
Dante, like Homer before him, was fascinated by the human urge to go beyond the known. It's thanks to that urge that we started walking out of Africa a hundred thousand years ago. It also helps explain why some people kayak over waterfalls.
Awesome video, BTW.
