In a few moments all the stars came out above the intense blackness of the earth and the great lagoon gleaming suddenly with reflected lights resembled an oval patch of night sky flung down into the hopeless and abysmal night of the wilderness.
The passage describes a vivid scene where a dark, barren earth contrasts sharply with the sudden appearance of stars in the sky. As night falls, the lagoon reflects these celestial lights, creating an ethereal atmosphere. This imagery evokes a sense of wonder and mystery, emphasizing the beauty found within the darkness of the wilderness.
By likening the lagoon to a piece of the night sky, the author highlights the profound connection between nature and the cosmos. This scene encapsulates the themes of isolation and exploration present in Conrad's work, as the protagonist navigates both the external wilderness and his internal struggles amidst this stark yet beautiful landscape.
