Sebastian Cabot (c. 1474 – c. December 1557) was an Italian explorer, likely born in the Venetian Republic. He was the son of Italian explorer John Cabot (Giovanni Caboto) and his Venetian wife Mattea. After his father’s death, Cabot conducted his own voyages of discovery, seeking the Northwest Passage through North America for England. He later sailed for Spain, traveling to South America, where he explored the Rio de la Plata and established two new forts.
