Leaving Venice With This Secret Was Punishable by Death

This is the dark history of the mirror — an everyday object that was once the most valuable secret in the world. From the dim obsidian and polished bronze of the ancient world, to the glassmakers of Venice who perfected the first true reflection and were kept as treasured prisoners, to the industrial espionage and murder that erupted when France stole the secret to build the Hall of Mirrors at Versailles. We follow the fortunes paid for a single mirror, the workers slowly poisoned by mercury to make it shine, and the ancient dread that still survives in the superstitions we repeat today. A doorway to the soul. A secret worth murder. The most ordinary object in your home.
