Volume 9 — Memorial on Navigation and Conquest

[This memorial, addressed to Felipe II by Hernando de los Ríos, is prefaced by a letter from Luis Perez Dasmariñas, as follows:]

Sire: In these islands resides a person named Hernando de los Ryos, a colonel, a man of much information concerning important matters, and particularly learned in mathematics and astrology, and possessed of such virtue and such uprightness of life, and so zealous and desirous of the service of God and your Majesty, and of the common welfare, that I know not if there be a man in these parts to exceed him in this; and may it please our Lord to give us many who shall succeed in being so disinterested in worldly things and earthly claims. At any rate, in the secular estate, in my opinion and perhaps that of many good men, I know not if you will find in this country, or even for the most part in others, a man of more learning, respectability, and virtue, accompanied by other good qualities and gifts with which God has graced him, and which are so well employed and profited by, as in himself. For his sole object is to serve God and desire his service and that of your Majesty, and the great good which can be accomplished in these regions; and he is not interested in Page 284the occupations and advantages of office, although it would be well indeed if all those who hold them had the qualifications that he has for them. At any rate, he has refused and rejected some of the best offices of this country, particularly an offer to be a royal official of the royal exchequer of your Majesty, when I desired him to be so during my government, as I understood that he was a fit man for the service of God and of your Majesty. It was impossible, however, to persuade him. His intention, as I have understood, is to become a priest. He has made a very peculiar instrument of general usefulness in many curious and important ways, particularly in navigation, for getting bearings and taking measurements, which are rendered very easy. I do not send one to your Majesty, because he has not finished a book of description and explanation of this instrument. I have persuaded him to send one to your Majesty, as I also shall do, as I consider it well that your Majesty should have information of the learning, virtue, and parts which are found in him, as it may be of use and importance for the service of God and your Majesty—whom may our Lord protect many years of life, according to His power and the desire and need of us all. Manyla, June 27, 1597.

Memorial

With this astrolabe, which, with the aid of God, I have discovered, can be found the altitude from the pole, and the latitude of any region whatsoever at any hour of the day, and at the same time it will tell the hour, in the same way that it gives directions at night by any known star more easily than the mariners usually take it at midday. Besides this, it also serves like other astrolabes at midday, to indicate the various points of the compass, and show and verify with precision the deviations and deflection of the needle from the pole. In this way it serves to give the longitude where one is sailing, on whatever parallel to the equinoctial. Likewise it shows the position of the stars, even when all their latitudes [i.e., altitudes?] and declinations are unknown, so easily that even the most uninstructed can in a short time learn it. It is of use in other curious, useful, and important ways, for the perfection of this art, which can by its aid be verified. As it is an article so curious and useful, the said Luis Perez de las Marinas persuaded me to give an account of it to your Majesty, with a brief relation and discourse concerning the information which I have of these parts.

Although your Majesty has so little profit from these islands, we can see that it is a place of much importance for the service of your Majesty, and the spread of the most holy Catholic faith, since it has as neighbors, and surrounding it, many extremely rich and fertile countries. The disposition of matters is ... that they are propitious for your Majesty Page 287easily to make himself master of those lands. Your Majesty will see that this is so by the relations which the governor of these islands, and likewise Don Luis Perez de las Marinas, formerly governor of them, have sent you.

It is very necessary and expedient that several expeditions and conquests should be made in these parts for the service of your Majesty in view of the advantages that the Castilians would gain if they held a good post on the mainland—such as the kingdom of Sian, which is very rich and abounds in many things, and could be conquered and kept with a thousand men, according to everyone who has been there; or the kingdom of Canboxa, which is seeking our friendship, and offers to maintain troops at its own expense, and furnish them to us on occasions when aid may be necessary; or the kingdom of Chanpa, which could be conquered and maintained with three hundred men, and is the pass for this archipelago, and the key to Cochinchina, which is a very rich and fertile country, and could be conquered with a thousand or fifteen hundred men. The latter is more to the east than the said kingdoms between Chanpa and China, close to these islands, and with everyone ... of them on account of the many wars and enmities, which exist among them, this ... would be easy to spread the royal sovereignty of your Majesty with great ... so that all would seek for our friendship and alliance; for ... said, and with a little shrewdness and cunning a great deal of it might be gained ... with our protection and oversight the ministers and preachers ... could spread over all those parts in safety; to convert those souls and bring such a great multitude of Page 288heathen to the true knowledge of our Lord God. It is no little shame to consider that among those peoples, by way of Burnei and other Mahometans the venom and poison of their false doctrine is being scattered—although this is of so great importance, as your Majesty must see by the accounts which are sent you, and to which I refer.

It is of no less importance to give an account to Page 290your Majesty of two routes which can be explored at little expense and are short and easy. The first is by the strait which is called Danian [i.e., Anian], which lies between the farthest land of China and the regions of Nueva España ... a relation which I [received] there, which was left in manuscript by Fray Martin de Rada, of the order of St. Augustine, a great mathematician, of whom your Majesty had information in this ... of the letter.

It may also be inferred that these seas communicate with each other, because on the coast of Nueva España those who are coming from these islands in forty-two degrees latitude see a great number of whales, who must enter by that strait to winter in a warm climate. Accordingly your Majesty can send as many troops as you wish in this way with ease, and become lord of these parts. Although this voyage being in so high a latitude appears to entail some difficulty, there will be none, in view of the fact that by leaving España at the end of March, when they arrive in the high latitudes it is the hot season, and the days are long and the weather is fair; and the winds are brisas, as is necessary. Thus they will come here very easily, and in the island of Hermosa, in this port of Kielang, your Majesty may send and have stationed a considerable fleet, safe and well provisioned; for the country is fertile, and productive of food stuffs, rice, meat, and so much fish that they load every year two hundred ships for China—especially as the coast of China is so near, where for money ... what they wish in abundance; and also from Japon they can ... examine.

These two explorations will be very easy to make, at little expense, from these islands rather than from España. For their entrances from that side are difficult to find, and from this side one cannot go astray, nor is there any obstacle. The first year after Gomez Perez de las Marinas arrived in this country as governor, he conferred with me about sending me to explore the strait of Danian. By reason of the expedition which he intended to make to Maluco, he deferred the other; and when he was so unfortunately killed it put an end to the project. He, I believe, Page 294would have far advanced the affairs of these parts if he had lived, and would have done good service for your Majesty, judging by the valor and zeal which he showed; and his absence, and the need for him, have brought this city to a sense of what they owe him, and now they deplore his loss.

I have given this brief account to your Majesty, begging humbly that you will pardon my boldness (which zeal for your royal service and the good of these regions has caused) in advising your Majesty, that you may see how glorious opportunities our Lord God has kept for you to extend and widen out the holy Catholic faith. But it is necessary that your Majesty should entrust this to a person of high rank and great worth, and that he should not come for a limited time, with the intention of gathering riches and the fruit of the land, and then returning; for those who have this intention will not be watchful for its welfare, nor zealous for the honor of God and for the service of your Majesty. I have informed the governor of these islands, Don Francisco Tello, of this, so that he may write to your Majesty and make use of the opportunities which are offered him. I know not what he will do. May our Lord God, for whom we labor, protect your Majesty many years, according to the needs of Christendom, and augment your estate with greater lands and majesty, for His glory and the good of ... may it prosper. Manila, June 27, 1597.

[Endorsed: “Examined on the thirteenth of September of 1599. As to what he says of the astrolabe, have a copy made and delivered to Cespedes, that he may examine it and give his opinion in regard to it. As for the rest, join everything in regard to this Page 295matter, and have all the papers brought in a bundle.”]

[Memoranda at beginning of document: “Memorial addressed to the king, dated at Manila on June 27, 1597, by Colonel Hernando de los Rios, which gives an account of a book which he is engaged in composing, concerning the approved usage and art of navigation, and of the importance of taking a port on the mainland of China, and particularly in the island of Hermosa, of which he gives a very circumstantial description, accompanying it with his map, and finally a very valuable discourse on the two routes which are the most expeditious and direct for navigation from Spaña to those kingdoms, that can be found. The first is through a channel or narrowing of the sea which enters Nuebo Mexico above Florida at forty-five degrees latitude, according to the information received from Father Federico of the Society of Jesus, and from a friar of the order of St. Augustine, who was very learned in cosmography, and who died in that city. The other is through the strait called Anian. There is inserted in the said memorial a relation which was left written by Fray Martin de Rada, of the order of St. Augustine. It was received from a Vizcayan named Juanes de Rivas, a native of San Sevastian, wherein he sets forth that various Portuguese have passed by that way to Yndia and China, and by way of Ucheo returned to Lisboa in forty-five days of voyage. He gives a condensed description of the ship's courses, and the navigation which must be accomplished until they have arrived in the harbor, either here or in China, etc., etc.

Memorial directed to the king of España by Benito Page 296Escoto, a Genoese noble, in the year 1616, giving an account of a certain method which he had discovered of putting together certain tables of longitudes in maritime voyages and navigation, etc.; and to find that navigation which, up to that time, so many serious men and mariners had sought and had not found—namely, the passage by the northern part of China, Japon, Malucas, and Philipinas, with a condensed discourse concerning the advantages which will accrue from the proposed action. And in continuation a letter from the prior of the convent of Santa Maria, written to ... in recommendation of the good circumstances and worthy qualities both of the author and his work.”] Page 297
