those islands were within its western hemisphere. In the early 16th century, the Treaty between Spain and Portugal, concluded at Vitoria; 19 February 1524 and called for the Badajoz Junta to meet in 1524, at which the two countries tried to reach an agreement on the anti-meridian but failed. They finally agreed in the Treaty of Zaragoza that Spain would relinquish its claims to the Moluccas upon the payment of 350,000 ducats of gold by Portugal to Spain. To prevent Spain from encroaching upon Portugal's Moluccas, the anti-meridian was to be leagues or 17° to the east of the Moluccas, passing through the islands of Las Velas and Santo Thome. This distance is slightly smaller than the 300 leagues determined by Magellan as the westward distance from los Ladrones to the Philippine island of Samar, which is just west of due north of the Moluccas. The Moluccas are a group of islands west of New Guinea. However, unlike the large modern Indonesian archipelago of the Maluku Islands, to 16th-century Europeans the Moluccas were a small chain of islands, the only place on earth where cloves grew, just west of the large north Malukan island of Halmahera (called Gilolo at the time). Cloves were so prized by Europeans for their medicinal uses that they were worth their weight in gold. 16th- and 17th-century maps and descriptions indicate that the main islands were Ternate, Tidore, Moti, Makian and Bacan, although the last was often ignored even though it was by far the largest island. The principal island was Ternate at the chain's northern end (0°47′N, only in diameter) on whose southwest coast the Portuguese built a stone fort (Forte de São João Baptista de Ternate) during 1522–23, which could only be repaired, not modified, according to the Treaty of Saragossa. This north–south chain occupies two degrees of latitude bisected by the equator at about 127°24′E, with Ternate, Tidore, Moti, and Makian north of the equator and Bacan south of it. Although the treaty's Santo Thome island has not been identified, its "Islas de las Velas" (Islands of the Sails) appear in a 1585 Spanish history of China, on the 1594 world map of Petrus Plancius, on an anonymous map of the Moluccas in the 1598 London edition of Linschoten, and on the 1607 world map of Petro Kærio, identified as a north–south chain of islands in the northwest Pacific, which were also
