Cinnamon was once so valuable that merchants claimed it was harvested from the nests of giant winged serpents, a fabrication designed to keep the price sky-high and the source a mystery. This elaborate deception, recorded by the Roman naturalist Pliny the Elder, persisted for centuries, with traders telling tales of cinnamon birds collecting the bark from unknown lands to build their nests. The reality was far less mythical but equally guarded; the spice was imported to Egypt as early as 2000 BC, yet its true origins remained hidden from the Mediterranean world for millennia. Ancient writers like Herodotus and Aristotle named Arabia as the source, but the actual trade routes were kept secret to protect the monopoly of those who controlled the flow of the spice. Even Pliny noted that cinnamon was brought around the Arabian Peninsula on rafts without rudders or sails, relying on winter trade winds to move the precious cargo. The value of the spice was so immense that a Roman pound of cassia could cost up to 1,500 denarii, which equated to the wages of fifty months of labor for an agricultural worker. The Emperor Nero famously burned a year's supply of the city's cinnamon at the funeral of his wife Poppaea Sabina in AD 65, a display of wealth that would have been impossible to replicate today.
The Dutch Monopoly and the Ceylon Trade
For centuries, the source of cinnamon remained a mystery to the Western world, with Europeans believing it grew at the source of the Nile in Ethiopia or in the lands of Arabia. It was not until the 17th century that the truth about the spice's origins was fully revealed and exploited. In 1638, Dutch traders established a trading post in Sri Lanka, and by 1640, they had taken control of the manufactories, expelling the Portuguese by 1658. A Dutch captain reported that the shores of the island were full of the spice, and one could smell cinnamon eight leagues out to sea when downwind. The Dutch East India Company revolutionized the harvesting process, moving from wild harvesting to cultivating their own trees to ensure a steady supply. The British later seized control of Ceylon from the Dutch in 1796, and in 1767, Lord Brown of the British East India Company established the Anjarakkandy Cinnamon Estate in Kerala, India, which eventually became Asia's largest cinnamon estate. The disruption of the Venetian monopoly on the spice trade by rising Mediterranean powers like the Mamluk sultans and the Ottoman Empire was a primary driver for European exploration, pushing them to find new routes to Asia and ultimately leading to the age of discovery.The Science of the Bark and the Leaf
Cinnamon is an evergreen tree characterized by oval-shaped leaves, thick bark, and a berry fruit, but the spice itself comes from a very specific part of the plant. When harvesting the spice, the bark and leaves are the primary parts used, and the process is incredibly labor-intensive. The stems must be processed immediately after harvesting while the inner bark is still wet. Workers scrape off the outer bark, then beat the branch evenly with a hammer to loosen the inner bark, which is then pried off in long rolls. Only a small fraction of the inner bark is used, while the outer, woody portion is discarded, leaving meter-long cinnamon strips that curl into rolls known as quills on drying. The processed bark dries completely in four to six hours in a well-ventilated and relatively warm environment. Once dry, the bark is cut into lengths for sale. A less-than-ideal drying environment encourages the proliferation of pests, which may require treatment by fumigation with sulfur dioxide, a practice approved by the European Union in 2011 for up to 100 parts per million in Sri Lankan bark.
