Born in the Purple: How a Sea Snail Created the Ancient World's Most Expensive Color

In AD 301, a Roman price law set one pound of purple silk at the same price as a live lion. The value lay in the color, not the silk. Tyrian purple, made from the glands of Mediterranean sea snails, was the most expensive dye of the ancient world, and for more than three thousand years it marked kings, senators, and emperors. This full-length documentary from The Long View traces the history of Tyrian purple: how it was made, who made it, how it was traded across the Mediterranean, and why a single color came to stand for power. The story runs from Bronze Age workshops on Minoan Crete and the island of Aegina, through the Phoenician dye-works of Tyre and Sidon, to Roman sumptuary laws, the Byzantine "born in the purple," and the 1856 discovery that made purple cheap. In this documentary: • How murex sea snails produce 6,6'-dibromoindigo, and why it took about 12,000 snails to make 1.4 grams of dye • Pliny the Elder's account of the ancient dyeing process • The debate over who invented purple: Minoan Crete or Phoenicia • The Phoenician trade network, from Lebanon to Carthage and Morocco's Purple Islands • The 3,000-year-old purple wool found at Timna, Israel • Alexander the Great's purple treasure at Susa • Roman rank, Julius Caesar, Nero, and the king Caligula executed over a purple cloak • Diocletian's Edict on Maximum Prices and the price of purple • Byzantine imperial control of the dye and the end of the trade after 1453 • William Perkin, mauveine, and the end of purple's scarcity • Common myths about royal purple, corrected CHAPTERS 00:00 Cold Open: The Price of a Lion 01:54 Part I: A World of Fading Color 04:53 Part II: Who First Made Purple? 10:19 Part III: How Tyrian Purple Was Made 13:35 The Phoenician Trade Network 15:23 A Discovery in the Desert: Timna 16:57 Purple and Kings: Persia and Alexander 18:36 Rome: Purple as Rank 21:38 The Price Ceiling of AD 301 22:31 Purple Becomes Imperial Property 24:22 Part IV: Why Purple? 28:36 Part V: Consequences and Decline 31:07 Part VI: Legacy and Misconceptions 34:12 Closing KEY SOURCES Pliny the Elder, Natural History, Book 9 Strabo, Geography 16.2.23 Plutarch, Life of Alexander 36 Suetonius, Lives of the Caesars Diocletian, Edict on Maximum Prices (trans.
