On the second afternoon the Prince, in his impatience, came early to the shadowy garden. The Princess Liria was not to be found, so Porphyrio wandered away into the dark alleys by the pools. Suddenly he found himself looking at his own reflection in a huge round mirror which two marble statues supported between them, one at each side. Happening to move a little, the Prince discovered that his reflection did not move! He lifted an arm, the image remained motionless; he shook his head, the mirror gave no sign. Puzzled, Porphyrio left the spot, and saw his reflection remaining behind the glass. Presently he heard the welcome footsteps of Liria. And as the lovers walked and talked and discussed plans of escape, the Prince chanced to tell of the mirror he had found. Uttering a little gasp of alarm, the Princess cried: “Now we are lost indeed! Yon mirror is a mirror of memory, and reveals to the Magician the faces of those who walk these paths. As soon as he sees your reflection therein,--and he gazes into the glass every eve,--his demons will be sent in search of you. There is one hope and one only. “Go you once more to the sea; follow the cliff for a league to the west of the promontory, and you will find at its base the opening of an ocean cave. When you arrive there the tide will be at half-flood, and the entrance will still be visible above the waves. Fight your way within and climb to the cavern’s height. Little by little the rising tide will seal the portal and hide you from the search. Make haste, dear Porphyrio, for there is not an instant to lose! Oh, that I had warned you!” [Illustration: _The image in the mirror stood still_] Ragingly angry with himself for being a meddlesome fool, Porphyrio hurried down to the sea and sought out the cave. Twilight was at hand; the tide was rising fast, already the entrance was almost closed by the sea. Buffeted by the breakers and tossed against the cliff as he strode, the Prince at length made his way into the cave and climbed to a shelf of rock above the height of the tide. A few minutes later, the water closed the entrance completely, thus imprisoning Porphyrio in a hollow darkness through which the ebb and flow of the outer sea swept with chuckles and whispering laughter. All night long waited Porphyrio in the cold, watery dark. Toward the end of the Prince’s vigil, the earth suddenly shook, the waters hushed, and through the silence and the dark Porphyrio heard the long thunder of a mighty overthrow. “What can that be?” thought he. When the first red rays of the sun streamed along the rocky floor of the cave, Porphyrio descended from his refuge, and walked out of the cave-mouth to the sea.
