From the recesses of the temple -- if temple it were -- from the inmost shrines of the shrouded cavern, unearthly music began to sound of itself; with wild modulation, on strange reeds and tabors. It swept through the aisles like a rushing wind on an Folian harp; at times it wailed with a voice like a woman's; at times it rose loud in an organ-note of triumph; at times it sank low into a pensive and melancholy flute-like symphony. It waxed and waned; it swelled and died away again; but no man saw how or whence it proceeded.'
