so his line at 47°24′ W. corresponds to the actual 45°38′ W. based on his other numerical data. Enciso further described the coastal features near which the line passed, but in a very confused manner that might place the line as far west as the mouth of the Amazon between 49°W and 50°W. In 1524, the Castilian pilots Thomas Duran, Sebastian Cabot (son of John Cabot), and Juan Vespuccius (nephew of Amerigo Vespucci) gave their opinion to the conference at Badajoz, whose failure to resolve the dispute led to the Treaty of Saragossa. The pilots specified that the line should be understood as 22° plus about west of the center of Santo Antão, the westernmost Cape Verde island. Based on their understanding of the equator, Harrisse concludes they intended 47°17′ W. on their sphere (3.1% smaller than ours) or 46°36′W on the actual globe. At the same conference, the Portuguese presented a globe on which the line was marked as 21°30′ west of Santo Antão, which would place it at 47°16′52″ W. when adjusted to match the actual circumference of the earth, nearly identical to the Spanish suggestion. However, the Badajoz conference disbanded without reaching any formal settlement on any issue. The 1529 Treaty of Zaragoza, agreed to by the Spanish king Charles I (Emperor Charles V) and the Portuguese king John III, implicitly assumes within its measurements of a new eastern line that the leagues of the two treaties should be understood as a geographical league equivalent to 4/70th of an equatorial degree, placing the line between 43°56′ and 46°18′ W. depending on the island chosen. Note, however, that the 1529 Diogo Ribeiro mapgenerally considered to represent the now lost Spanish standard map used to finalize the agreement at Zaragozaplaced its own delineation of the Tordesillas agreement much further west, around 49°45′ W. Antimeridian: Moluccas and Treaty of Zaragoza Initially, the line of demarcation did not encircle the earth. Instead, Spain and Portugal could conquer any new lands they were the first to discover, Spain to the west and Portugal to the east, even if they passed each other on the other side of the globe. But Portugal's discovery of the highly valued Moluccas in 1512 caused Spain to argue in 1518 that the Treaty of Tordesillas divided the earth into two equal hemispheres. After the surviving ships of Magellan's fleet visited the Moluccas in 1521, Spain claimed that
