Then the suburbs appeared, and finally a great lone building on a hill, of simpler architecture than the other structures, and in much better repair. It was dark and low and covered four sides of a square, with a tower at each corner, a paved court in the centre, and small curious round windows all over it. Probably it was of basalt, though weeds draped the greater part; and such was its lonely and impressive place on that far hill that it may have been a temple or a monastery. Some phosphorescent fish inside it gave the small round windows an aspect of shining, and Carter did not blame the sailors much for their fears. Then by the watery moonlight he noticed an odd high monolith in the middle of that central court, and saw that something was tied to it. And when after getting a telescope from the captain's cabin he saw that that bound thing was a sailor in the silk robes of Oriab, head downward and without any eyes, he was glad that a rising breeze soon took the ship ahead to more healthy parts of the sea.
