Giovio Globe Mercator Globe

A thorough survey of the islands throughout the Giovio Globe has not yet been undertaken, while a quick look at the Pacific is confusing. In his account of Magellan's voyage, Antonio Pigafetta first reports two islands one at 15 degrees S and one at 8 degrees S latitude. Magellan calls these islands the Unfortunate Islands and Pigafetta names one of them Tiburoni (Shark) Island. These islands are not where they are supposed to be on the Giovio Globe (or the Mercator globe), though they appear as I. Tibrones and I. S. Paolo on Gastaldi's 1546 world map and most subsequent maps at about 250 degrees longitude. On both the Mercator and Giovio globes, the Unfortunate Islands show up much further to the East, at about 210 degrees of longitude. These Unfortunate Islands are the only Pacific islands on Mercator's globe. By contrase, the Giovio Globe shows two unnamed islands just slightly north of the Equator at 265 degrees of longitude. More interestingly, the Giovio Globe shows another island just north of the Equator, indistinctly labeled Insula Latrons ( a corruption of Ladrones?),at about 232 degrees of longitude. This island may represent the Island of Thieves (Ladrones) mentioned by Pigafetta. As such, it is properly located north of the Equator, in agreement with Pigafetta's account. Just to make things more confusing, Vopell, in his great 12 sheet world map, indicates a Insulae Latronium jsut south of the Equator at about 210 degrees of longitude, and the same islands jump around the Pacific on other maps of the mid 16th century. Clearly misunderstandings, mistranslations and mistranscriptions worked to create a confusing picture in the Pacific.

  More work remains to be done surveying the islands of the Giovio Globe.
