H. P. LovecraftI could not help feeling that they were evil things-- mountains of madness whose farther slopes looked out over some accursed ultimate abyss. That seething , half-luminous cloud-background held ineffable suggestions of a vague, ethereal beyondness far more than terrestrially spatial; and gave appalling reminders of the utter remoteness, separateness, desolation, and aeon-long death of this untrodden and unfathomed austral world.
