21. Almost the same has happened to our España; what fear, what respect, what terror, did not our armadas inspire in the four quarters of the world? There was no power that could resist them; but, not to linger on the glories of our nation, I leave that to the histories which relate them--especially those of the reigns of the pious king Don Fernando, the Catholic monarchs, the emperor Don Carlos Fifth, Don Phelipe Second, and Don Phelipe Fourth, who certainly protected navigation and commerce. I will assert [here] only what answers my purpose: that our navy declined, our great manufactures in Sevilla, Segovia, and other places retrograded, and our commerce deteriorated, with the continual wars; and, as we did not repair this damage, we were at the same time promoting the commerce of the other nations. These have made themselves rich through our negligence and inactivity--selling to us all the more commodities the more we abandoned manufactures, and with their gains increasing their shipping the more that we gave up shipbuilding--until in these latest reigns our shipping and commerce were reëstablished. But it is necessary to extend our commerce further, in proportion to our vast domains; otherwise, we keep them greatly exposed [to danger]. For it has been now thoroughly proved that navigation and commerce have rendered formidable and terrible the forces and power of the nations who have practiced them, as also that from the decay or neglect of these activities has proceeded the ruin of kingdoms. Chapter Second: Of the liberty of the Spaniards to navigate by way of the Cape of Good Hope 1. Some may think that this navigation is prohibited to the Spaniards by the treaties of peace, and that on this account we have not established a commerce like that of the Dutch, English, French, Swedes, Danes, and other nations. But it is certain that there is no such prohibition, and that our natural inactivity, laziness, and lack of application to commerce, has been the cause of our not undertaking the aforesaid navigation, which is equally free to us as to all the other powers. For the prohibition that the Englishman, the Dutchman, and the rest can lay upon us is, that our ships may not enter their ports, just as they have been forbidden to enter our ports; but they cannot hinder us from navigating in all the seas of the world, in accordance with natural right and the law of nations. That law does not allow the dominion of the sea to any power, according to Grotius, Heinsius, and others--contrary to the Mare clausum [i.e., "closed sea"], of the Englishman Selden, [142] who in regard to the dispute of the year 1653 defended the [English] dominion of the White Sea, and the right of forbidding this navigation to the Dutch; but they maintained their freedom with powerful fleets, and with the same arguments which justify the freedom which the Spaniards possess for navigating by way of the Cape of Good Hope.
