Sebastian Cabot: The Venetian Explorer of Three Crowns
Sebastian Cabot (c. 1474 – c. December 1557) was a distinguished Venetian explorer whose career spanned the service of three major powers: the Kingdom of England, the Crown of Aragon, and the Holy Roman Emperor. Born into a family of navigators, Cabot spent his life charting the unknown reaches of the Atlantic and Pacific, contributing significantly to the early European understanding of North America and the search for a route to Asia.

- Later Career: Served as governor of the Muscovy Company, advising on English ventures to the north.
Early Life and Conflicting Origins
The exact details of Sebastian Cabot's birth remain a subject of historical debate. While he was likely born in the Venetian Republic around 1474, Cabot provided varying accounts of his origins depending on his audience. To the Englishman Richard Eden, he claimed to have been born in Bristol; however, he told the Venetian ambassador Gasparo Contarini that he was Venetian but educated in England.
His father, John Cabot, a Venetian citizen, moved the family to England by 1495. Sebastian, along with his brothers Ludovico and Santo, was named in the royal letters patent issued by King Henry VII in March 1496, which authorized their father's expeditions to the "New Found Land." This early exposure to maritime exploration laid the foundation for Sebastian's own career.
The 1494 Controversy and Early Voyages
In a 1544 map of North America, Sebastian Cabot included a Latin text claiming he had discovered North America with his father in 1494—three years before the widely accepted 1497 voyage. Historians suggest this may have been a strategic inaccuracy. Since Cabot was funded by Charles V (the Holy Roman Emperor and King of Spain) at the time, he may have sought to suggest that the first discovery was funded by Castilians or Portuguese rather than the English or French.
Cabot's independent career began in 1504 when he led an expedition from Bristol using two ships, the Jesus and the Gabriel. This voyage returned with salted fish, indicating a commercial fishing purpose. For these services, King Henry VII granted him an annuity of £10 in 1505.
The Quest for the Northwest Passage
Between 1508 and 1509, Cabot led one of the first attempts to locate the Northwest Passage. He reached high latitudes, encountering icebergs and reporting an open passage of water, though he was eventually forced to turn back. Some accounts suggest he may have reached the entrance of Hudson Bay.
According to records from 1516, Cabot sailed south along the North American coast, potentially reaching as far as the Chesapeake Bay. Upon his return to England, he found that King Henry VII had died; his successor, Henry VIII, showed significantly less interest in New World exploration, which eventually prompted Cabot to seek opportunities elsewhere.
Service to the Spanish Crown
Seeking better financial support, Cabot moved to Spain in 1512 to serve King Ferdinand II of Aragon. After a brief return to England following Ferdinand's death in 1516, he returned to Spanish service in 1525 as captain general of a fleet. His mission was twofold: to use astronomical observations to determine the precise demarcation line of the Treaty of Tordesillas (the agreement dividing newly discovered lands between Spain and Portugal) and to transport settlers to the Molucca Islands.
This expedition, which departed in 1526 with four ships and 250 men, was fraught with difficulty. After facing mutinies and attacks by Indigenous populations at Espíritu Santo, Cabot eventually returned to Seville in 1530 with only one ship and 24 men.
Later Years and the Muscovy Company
In his final years, Cabot remained an influential advisor on navigation. In 1553, he became the governor of the Muscovy Company, where he worked alongside the scholar John Dee to prepare expeditions led by Sir Hugh Willoughby and Richard Chancellor. He also served as life-governor of the Company of Merchant Adventurers.
Cabot's life ended around December 1557, as evidenced by the cessation of his quarterly pension payments.
Personal Life and Partnerships
Cabot was married twice. His first wife, Joanna, died around 1514. In 1523, he married Catalina de Medrano, a widow with significant business expertise. Catalina played a vital role in Cabot's life, managing family finances and handling business affairs through a power of attorney—a rare arrangement for women of that era. Her social connections and financial management helped Cabot navigate the complex social and economic challenges of Seville.
