Huge spiral, ending in a most difficult maze

"There was a certain cave near Thebes in Egypt which resembled a shepherd’s pipe, since as it followed its winding course in the depths of the earth it formed a natural spiral; for it did not take a straight course at the opening and then branch off into straight-running corridors, but winding about under the mountain it made a huge spiral, ending in a most difficult maze. In it was set up an image of a Satyr wrought in marble. He stood on a base in the attitude of one making ready to dance, and lifting the sole of his right foot backward he not only held a flute in his hand but also was being the first to leap up at its sound; though in reality the flute’s note was not reaching the player’s ear, nor yet was the flute endowed with voice, but the physical effect which flute-players experience had been transferred to the stone by the skill of the artist."
