Both from the nature of this treatise on the origin and progress of maritime discovery, and from respect to the memory of Hakluyt, the father of our English collections of voyages and travels, it has been selected for insertion in this place, as an appropriate introduction to the _Second Part_ of our arrangement; because its author may be considered as almost an original authority for the early discoveries of the Portuguese and Spaniards. Although it may be considered in some measure as not precisely conformable with our plan, yet one portion of this summary is directly in point; and, the whole being curious, and in no respect tedious, it is here given entire; changing the antiquated English of Hakluyt into modern language. Although said in its title to extend to the year 1555, the chronological series of Galvano properly ends in 1545; and the only subsequent incident, is a very slight notice of the voyage of Sir Hugh Willoughby and Richard Chancellor, towards the White Sea, in 1553. In the original translation, and in the Oxford collection, this treatise is preceded by a dedication from Hakluyt to _Sir Robert Cecil_; and another dedication from the Portuguese editor, Francis de Sousa Tavares, to Don John, Duke of Aveira; both of which are here omitted, as having no directly useful tendency, except so much of the latter as refers to the history of Galvano. Besides the present discourse, Galvano composed a history of the Molucca Islands, of which he had been governor, which work has unfortunately been lost, or at least is unknown in this country. He is likewise said to have published at Lisbon in 1555, an account of the different routes by which the merchandize of India had been conveyed into Europe at different periods. Antonio Galvano, the author of the following Summary of the Discoveries of the World, was a Portuguese gentleman, who was several years governor of the Molucca Islands, and performed signal service to his country in that honourable station, by dissipating a formidable league, which had been entered into by the native princes of these islands, for the expulsion of the Portuguese; and, though possessing very inadequate resources for the protection of so important a commercial establishment, he confirmed and extended the dominion and influence of Portugal in these islands. When first appointed to the command in the Moluccas, Galvano carried with him a private fortune of 10,000 crusadoes, all of which he expended in the public service. Though he added a clear revenue to the crown of 500,000 crusadoes, in consequence of his successful, vigilant, and pure administration, he was so zealous in patronizing the propagation of the Christian religion among the islands belonging to his government, that, on his return to Lisbon in 1540, he was reduced to such extreme poverty, as to be under the necessity of taking refuge in the _hospital_, where he died in 1557.
