A fable created by Billy Corgan, front man of The Smashing Pumpkins. The story of Glass and the Machines of God is propagated by the band's album, Machina. The Machina lyric booklet contains one chapter of the fable, the rest of the chapters, except for chapter four, were posted online throughout the Mystery. Chapter four, The Story of June has never been posted.
The Mystery was based on Glass and the Machines of God.
Glass and the Machines of God is very simular in concept to Ziggy Stardust and the Spiders from Mars.
