Giovanni Caboto was born circa 1450 in Genoa, and moved to Venice around 1461; he became a Venetian citizen in 1476. Evidence suggests that he worked as a merchant in the spice trade of the Levant, or eastern Mediterranean, and may have traveled as far as Mecca, then an important trading center for Oriental and Western goods.

He studied navigation and map-making during this period, and read the stories of Marco Polo and his adventures in the fabulous cities of Asia. Similar to his countryman Christopher Columbus, Cabot appears to have become interested in the possibility of reaching the rich gold, silk, gem and spice markets of Asia by sailing in a westward direction.

For the next several decades, Cabot’s exact activities are unknown; he may have been forced to leave Venice because of outstanding debts. He then spent several years in Valencia and Seville, Spain, where he worked as a maritime engineer with varying degrees of success.

Cabot may have been in Valencia in 1493, when Columbus passed through the city on his way to report to the Spanish monarchs the results of his voyage (including his mistaken belief that he had in fact reached Asia).

By late 1495, Cabot had reached Bristol, England, a port city that had served as a starting point for several previous expeditions across the North Atlantic. From there, he worked to convince the British crown that England did not have to stand aside while Spain took the lead in exploration of the New World, and that it was possible to reach Asia on a more northerly route than the one Columbus had taken.

In 1496, King Henry VII issued letters patent to Cabot and his son, which authorized them to make a voyage of discovery and to return with goods for sale on the English market. After a first, aborted attempt in 1496, Cabot sailed out of Bristol on the small ship Matthew in May 1497, with a crew of about 18 men.

Cabot’s most successful expedition made landfall in North America on June 24; the exact location is disputed, but may have been southern Labrador, the island of Newfoundland or Cape Breton Island. Reports about their exploration vary, but when Cabot and his men went ashore, he reportedly saw signs of habitation but few if any people. He took possession of the land for King Henry, but hoisted both the English and Venetian flags.

Cabot explored the area and named various features of the region, including Cape Discovery, Island of St. John, St. George’s Cape, Trinity Islands and England’s Cape. These may correspond to modern-day places located around what became known as Cabot Strait, the 60-mile-wide channel running between southwestern Newfoundland and northern Cape Breton Island.

Like Columbus, Cabot believed that he had reached Asia’s northeast coast. He returned to Bristol in August 1497 with extremely favorable reports of the exploration. Among his discoveries was the rich fishing grounds of the Grand Banks off the coast of Canada, where his crew was allegedly able to fill baskets with cod by simply dropping the baskets into the water.

In London in late 1497, Cabot proposed to King Henry VII that he set out on another expedition across the north Atlantic. This time, he would continue westward from his first landfall until he reached the island of Cipangu (Japan). In February 1498, the king issued letters patent for the second voyage, and that May Cabot set off once again from Bristol, but this time with five ships and about 300 men.

The exact fate of the expedition has not been established, but by July one of the ships had been damaged and sought anchorage in Ireland. Reportedly the other four ships continued westward. It was believed that the ships had been caught in a severe storm, and by 1499, Cabot himself was presumed to have perished at sea.

Some evidence, however, suggests that Cabot and some members of his crew may have stayed in the New World; other documents suggest that he and his crew returned to England at some point. A Spanish map from 1500 includes the northern coast of North America with English place names and the notation “the sea discovered by the English.”

In addition to laying the groundwork for British land claims in Canada, his expeditions proved the existence of a shorter route across the northern Atlantic Ocean, which would later facilitate the establishment of other British colonies in North America.

One of John Cabot's sons, Sebastian, was also an explorer who sailed under the flags of England and Spain.
