Luís Vaz de Torres, a Galician or Portuguese navigator who commanded the "San Pedro y San Pablo", the "San Pedrico" and the tender or yacht, "Los Tres Reyes Magos" during the 1605–1606 expedition led by Pedro Fernandes de Queiros in quest of the Southern Continent, proved the existence of a passage south of New Guinea, now known as Torres Strait. Commenting on this in 1622, the Dutch cartographer and publisher of Queiros' eighth memorial, Hessel Gerritsz, noted on his "Map of the Pacific Ocean:" "Those who sailed with the yacht of Pedro Fernando de Quiros in the neighbourhood of New Guinea to 10 degrees westward through many islands and shoals and over 23 and 24 fathoms for as many as 40 days, estimated that Nova Guinea does not extend beyond 10 degrees to the south; if this be so, then the land from 9 to 14 degrees would be a separate land".
