Then the following writ of the judges for Portugal was read. In substance it said that the maps presented by Castilla located the Cabo Verde islands farther west than they should be; that it was unnecessary to present maps showing their navigations, since the only thing they ought to discuss was the location of the Cabo Verde islands.
Then the judges for Castilla offered for a second time their map with the Cabo Verde islands, from which the measurements were taken.
In the afternoon the Portuguese deputies said in substance that the navigations should not be examined, but only the locations of the Cabo Verde islands with their respective distances. This ought to be done in order to determine the meridian at the three hundred and seventy leagues.
The Castilian deputies declared immediately that they were ready to do this, without prejudice of going on to the decision of the negotiations.
Those from Portugal measured the maps, finding several differences between the one of Castilla and their two—a large one and a small one.
Those from Castilla petitioned that the differences be pointed out and that the Portuguese deputies should state what they considered the truth; and that they were quite ready to acquiesce.
May 25. Ibid. Those of Portugal declared that they found differences in this place of one degree, in that of five, which they should try to reconcile. Neither had those of Castilla shown the locations of the Canaries and Cape San Vicente, and it was necessary to have these lands indicated.
The Castilian deputies offered a map with the lands in question, saying that, if this was the opinion of the Portuguese deputies they would conform to it, only they would take back the map presented first, being ready to conform with this opinion in order to get rid of the disputes which were blocking the decision.
The Portuguese deputies said it was quite late, and they would give their answer on the next day.
May 27. Ibid. The judges for Portugal asserted in regard to the location of the Cabo Verde islands: "We locate the island of Santiago in five and one-fourth degrees of longitude from Cape Verde; the islands of La Sal and Buena Vista in four; Sant Anton in eight; and San Nicolas in five and one-half."
