Marine archaeologists off the coast of Goa have located the wreckage of a mid-16th-century caravel believed to be part of a lost diplomatic fleet. The vessel, identified via lead-isotope analysis of its anchor, was carrying a mission from the Portuguese crown to the Zamorin of Calicut when it foundered during a monsoon.
Among the artifacts recovered is a pristine gilded astrolabe featuring unique hybrid iconography, alongside several lead-lined chests containing copper-plate treaties written in both Portuguese and Sanskrit. The findings offer a rare glimpse into the complex diplomatic and scientific exchanges that defined early maritime contact in the Indian Ocean, predating the formal establishment of colonial monopolies.
