The Portuguese having discovered in 1525 an island so near as this to New Holland, we must believe that the discovery of that continent followed very soon after that of this island. It was at that time that the controversies between the courts of Portugal and Spain were at their highest; the Portuguese, therefore, needed to be cautious respecting their new discoveries; they were obliged to conceal them carefully. It will not, therefore, be surprising that no mention was made in their works of the discovery of New Holland.
But, after having shown how much importance the Portuguese must have attached to the concealment of their discoveries, and having examined at what period the discovery of New Holland may have been made, it will be not less interesting to inquire how this discovery may have become known in France, and afterwards in England, so early as 1542. There was nothing at that time to induce the court of Portugal to disclose their discoveries to the court of France; there was nothing to bind these two courts in intimate union; on the contrary, their intercourse had for some time been rather cool. As a proof of this, the king of Portugal had in 1543 married his daughter Mary to Philip the Infant of Spain, without giving notice thereof to Francis I, who thereupon showed his vexation in his conduct towards Francis de Norough, the ambassador of Portugal, who, to avoid a rupture between the two courts, answered with considerable reserve. We cannot, therefore, presume that the court of Portugal would ever have frankly communicated its discoveries to the court of France.
For my part, if it is permitted me to offer a conjecture, I think that this information may have resulted from the faithlessness of Don Miguel de Sylva, bishop of Viseo, and secretary of La Purité, a favourite of the king of Portugal, who, according to De la Clede, left the kingdom about 1542, carrying with him some papers of importance with which
