"The House on the Abyss" by William Hope Hodgson

A descent into hell turns into a space-time wandering. On the threshold of the twentieth century, the traditional katabasis is now tinged with the gloomy hues of already Einsteinian cosmicism. In a universe that has lost its center for centuries, WH Hodgson tries for the last time to get an overview of the Whole. The vision that he gives us is that of a universe without holds, in perennial decay, dominated by unknown forces that embody chaos and death, anticipating what will be the typical nightmares of HP Lovecraft's sepulchral nihilism.
