[Note 5: See De Legatione Babylonica.]

I hardly know, after reading the writings of many men remarkable for their knowledge and veracity, what to think of the Nile. It is claimed that there are really two Niles, which take their rise either in the Mountains of the Sun or of the Moon, or in the rugged Sierras of Ethiopia. The waters of these streams, whatever be their source, modify the nature of the land they traverse. One of the two flows to the north and empties into the Egyptian Sea: the other empties into the southern ocean. What conclusion shall we draw? We are not puzzled by the Nile of Egypt, and the southern Nile has been discovered by the Portuguese, who, in the course of their amazing expeditions, ventured beyond the equinoctial line into the country of the negroes, and as far as Melinde. They affirm that it rises in the Mountains of the Moon, and that it is another Nile, since crocodiles are seen there, and crocodiles only live in streams belonging to the basin of the Nile. The Portuguese have named that river Senegal. It traverses the country of the negroes, and the country on its northern banks is admirable, while that on its southern banks is sandy and arid. From time to time crocodiles are seen.

What shall we now say about this third, or in fact, this fourth Nile? These animals, covered with scales as hard as the tortoise-shell the Spaniards under Columbus found in that river, and which, as we have said, caused them to name that stream Los Lagartos, are certainly crocodiles. Shall we declare that these Niles rise in the Mountains of the Moon? Certainly not, Most Holy Father. Other waters than those of the Nile may produce crocodiles, and our recent explorers have supplied proof of this fact, for the rivers do not flow from the Mountains of the Moon, nor can they have the same source as the Egyptian Nile, or the Nile of Negricia or of Melinde; for they flow down from the mountains we have mentioned, rising between the north and south sea, and which separate the two oceans by a very small distance.

The swamps of Darien and the lands which are covered with water after the inundations, are full of pheasants, peacocks of sober colours, and many other birds different from ours. They are good to eat, and delight the ear of the listener with various songs; but the Spaniards are indifferent bird-hunters, and are neglectful in catching them. Innumerable varieties of parrots, all belonging to the same species, chatter in this forest; some of them are as large as capons, while others are no bigger than a sparrow. I have already enlarged sufficiently on the subject of parrots in my First Decade. When Columbus first explored these immense countries he brought back a large number of every kind, and everybody was able to inspect them. Others are still daily brought here.

There is still, Most Holy Father, a subject which is quite worthy to figure in history, but I would prefer to see it handled by a Cicero or a Livy than by myself. It affords me such astonishment that I feel more embarrassed in my description than a young chicken wrapped in tow. We have said that, according to the Indians, the land separating the north from the south sea can be traversed in six days. I am not a little puzzled both by the number and size of the rivers described, and by the small breadth of that stretch of land; nor do I understand how such large rivers can possibly flow down from these mountains, only three days' march from the sea, and empty into the north ocean. I cannot understand it, for I presume that equally large rivers empty into the south sea. Doubtless the rivers of Uraba are not so important when compared with others, but the Spaniards declare that during the lifetime of Columbus they discovered and have since sailed upon a river the breadth of whose mouth, where it empties into the sea, is not less than one hundred miles. This river is on the borders of Paria, and descends with such force from the high mountains that it overwhelms the sea even at high tide or when it is swept by violent winds, driving back the waves before the fury and weight of its current. The waters of the sea for a large area round about are no longer salt but fresh, and pleasant to the taste. The Indians call this river Maragnon.[6] Other tribes give it the names Mariatambal, Camamoros, or Paricora. In addition to the rivers I have before mentioned, the Darien, Rio Grande, Dobaiba, San Matteo, Veragua, Boiogatti, Lagartos, and Gaira, there are also others which water the country. I wonder, Most Holy Father, what must be the size of these mountain caverns so near the seacoast, and, according to the Indians, so narrow, and what sources they have to enable them to send forth such torrents of water? Several explanations suggest themselves to my mind.

[Note 6: Just which river is meant is not clear. The description would seem to fit the Orinoco, but Maragnon is the native name for the Amazon. This last name is given exclusively to the upper part of the river in the Peruvian territory.]

The first is the size of the mountains. It is claimed that they are very great and this was the opinion of Columbus, who discovered them. He had also another theory, asserting that the terrestrial paradise was situated on the top of the mountains visible from Paria and Boca de la Sierpe. He ended by convincing himself that this was a fact. If these mountains are so immense, they must contain extensive and gigantic reservoirs.

If such be the case, how are these reservoirs supplied with water? Is it true, as many people think, that all fresh waters flow from the sea into the land, where they are forced by the terrible power of the waves into subterranean passages of the earth, just as we see it pour forth from those same channels to flow again into the ocean?

This may well be the explanation of the phenomenon, since, if the reports of the natives be true, nowhere else will two seas, separated by such a small extent of land, ever be found. On the one side a vast ocean extends towards the setting sun; on the other lies an ocean towards the rising sun; and the latter is just as large as the former, for it is believed that it mingles with the Indian Ocean. If this theory be true, the continent, bounded by such an extent of water, must necessarily absorb immense quantities, and after taking it up, must send it forth into the sea in the form of rivers. If we deny that the continent absorbs the excess of water from the ocean, and admit that all springs derive their supply from the rainfall which filters drop by drop into mountain reservoirs, we do so, bowing rather to the superior authority of those who hold this opinion, than because our reason grasps this theory.

I share the view that the clouds are converted into water, which is absorbed into the mountain caverns, for I have seen with my own eyes in Spain, rain falling drop by drop incessantly into caverns from whence brooks flowed down the mountainside, watering the olive orchards, vineyards and gardens of all kinds. The most illustrious Cardinal Ludovico of Aragon, who is so devotedly attached to you, and two Italian bishops, one of Boviano, Silvio Pandono, and the other, an Archbishop whose own name and that of his diocese I am unable to recollect, will bear me witness. We were together at Granada when it was captured from the Moors, and to divert ourselves we used to go to some wooded hills, whence a murmuring rivulet flowed across the plain. While our most illustrious Ludovico went bird-hunting with his bow along its banks, the two bishops and I formed a plan to ascend the hill to discover the source of the brook, for we were not very far from the top of the mountain. Taking up our soutanes, therefore, and following the river-bed, we found a cavern incessantly supplied by dropping water. From this cavern, the water formed by these drops trickled into an artificial reservoir in the rocks at the bottom where the rivulet formed. Another such cave filled by the dew is in the celebrated town of Valladolid, where we at present reside. It stands in a vineyard not farther than a stadium from the walls of the town and belongs to a lawyer, Villena, citizen of Valladolid, and very learned in the science of law. Perhaps moisture changed into rain is collected in little caves in the rocks and sometimes forms springs, due to the infiltration of water in the hills; but I wonder how Nature can produce such quantities of water from these meagre infiltrations! In my opinion, two causes may be conceded: the first is the frequent rains; the second, the length in this region of the winter and autumn seasons. The countries in question are so near to the equinoctial line that during the entire year there is no perceptible difference in length between the days and nights; during the spring and autumn, rains are more frequent than in a severe winter or torrid summer. Another reason is: if the earth really is porous, and these pores emit vapours which form clouds charged with water, it will necessarily follow that this continent must have a greater rainfall than any other country in the world, because it is narrow and shut in on each side by two immense neighbouring oceans. However it may be, Most Holy Father, I am quite obliged to believe the reports of the numerous persons who have visited the country, and I must record these particulars even though they appear for the most part contrary to truth. For this reason I have desired to expose my arguments, fearing that learned men, rejoicing to find occasion for attacking the writings of another, may judge me so wanting in judgment as to believe all the tales people tell me.
