"Dost hear me, I say, old ancestor? I call on thee to give me thy treasure. Dost hear, I say?" And he repeated the blow with greater violence. Disturbed by the shock, the brass plate beneath the picture started from its place, and fell to the ground. "What is this?" cried Rougemont, gazing into the aperture left by the plate. "Ha!--my invocation has been heard!" And, snatching up the lantern, he discovered, at the bottom of a little recess, about two feet deep, a stone, with an iron ring in the centre of it. Uttering a joyful cry, he seized the ring, and drew the stone forward without difficulty, disclosing an open space beyond it. "This, then, is the entrance to my ancestor's tomb," cried Rougemont; "there can be no doubt of it. The old Rosicrucian has kept his secret well; but the devil has helped me to wrest it from him. And now to procure the necessary implements, in case, as is not unlikely, I should experience further difficulty." With this he hastily quitted the room, but returned almost immediately with a mallet, a lever, and a pitchfork; armed with which and the lantern, he crept through the aperture. This done, he found himself at the head of a stone staircase, which he descended, and came to the arched entrance of a vault. The door, which was of stout oak, was locked, but holding up the light towards it, he read the following inscription: "POST C.C.L. ANNOS PATEBO, 1550." "In two hundred and fifty years I shall open!" cried Rougemont, "and the date 1550--why, the exact time is arrived. Old Cyprian must have foreseen what would happen, and evidently intended to make me his heir. There was no occasion for the devil's interference. And see, the key is in the lock. So!" And he turned it, and pushing against the door with some force, the rusty hinges gave way, and it fell inwards. [Illustration: The Tomb of the Rosicrucian.] From the aperture left by the fallen door, a soft and silvery light streamed forth, and, stepping forward, Rougemont found himself in a spacious vault, from the ceiling of which hung a large globe of crystal, containing in its heart a little flame, which diffused a radiance, gentle as that of the moon, around. This, then, was the ever-burning lamp of the Rosicrucians, and Rougemont gazed at it with astonishment. Two hundred and fifty years had elapsed since that wondrous flame had been lighted, and yet it burnt on brightly as ever. Hooped round the globe was a serpent with its tail in its mouth--an emblem of eternity--wrought in purest gold; while above it were a pair of silver wings, in allusion to the soul. Massive chains of the more costly metal, fashioned like twisted snakes, served as suspenders to the lamp. But Rougemont's astonishment at this marvel quickly gave way to other feelings, and he gazed around the vault with greedy eyes.
