An excavation in the Bay of Cádiz has unearthed 18 silver ingots that researchers link to maritime smuggling networks from the time of the Spanish Empire. The find suggests that the illegal cargo may have been lost during a storm or a naval confrontation. Analyses will determine the origin of the metal and the exact circumstances of the shipwreck.
Isotopic analyses to trace the origin of the metal 🔬
The ingots will undergo lead isotope and trace element analysis using mass spectrometry. This technique allows comparing the metal's composition with documented historical mines at Cerro Rico de Potosí or in Mexico. Additionally, the remains of the wreck will be carbon-14 dated, and the hull wood will be studied to identify the type of vessel and its likely route, helping to reconstruct the illegal traffic of the era.
Smuggling, that classic that never goes out of style 😏
Because there's nothing like a good undeclared silver shipment to brighten an archaeologist's day. While Empire officials tried to control trade, some preferred to sail with holds full of undocumented ingots. In the end, the storm or the cannon shot delivered poetic justice: the silver ended up on the seabed, patiently waiting for someone to find it centuries later.
