From the “Tratado” of Antonio Galvam. 1563. (Extract.)

In this same year, 1500, it is reported that Gaspar Corte Real craved a general licence of the King Dom Manoel to go and discover a new land. He departed from the island of Terceira with two ships, armed at his own cost, and went to that region which is under the 50th degree of north latitude, a land now called by his name. He returned safely to the city of Lisbon. Taking this route once more, the ship in which he went was lost, and the other returned to Portugal. For this cause his brother, Miguel Corte Real, went in search of him, with three ships, armed at his own cost. Arrived on that coast, as there were so many bays and estuaries, each ship entered into her own port, with this rule, that they should all meet again on the 20th of August. The two other ships did so; and seeing that the ship with Miguel Corte Real did not come at the appointed time, after some time they returned to this kingdom, and never more had tidings of him, nor did other memory of him abide. The country is called the land of the Corte Reals to this day.
