A groundbreaking deep-sea survey off the coast of Cornwall has identified a Bronze Age shipwreck containing a rare cargo of tin ingots and animal-fat tallow, revealing a direct maritime trade link between the British Isles and the Mycenaean civilization of Greece. Using advanced submersible mass-spectrometry, researchers confirmed that the tin originated from local Cornish mines, providing the first physical evidence of a 3,500-year-old 'Tin and Tallow' route.
This discovery reshapes our understanding of prehistoric global trade, suggesting that ancient mariners navigated treacherous Atlantic waters to source the essential components for bronze production. The presence of tallow, likely used for waterproofing and lighting, suggests a highly organized logistical network that spanned the length of the European continent.
