Having discoursed of trees, vegetables, and fruits, let us now come to living creatures. Besides the lions and tigers[3] and other animals which we already know, or which have been described by illustrious writers, the native forests of these countries harbour many monsters. One animal in particular has Nature created in prodigious form. It is as large as a bull, and has a trunk like an elephant; and yet it is not an elephant. Its hide is like a bull's, and yet it is not a bull. Its hoofs resemble those of a horse, but it is not a horse. It has ears like an elephant's, though smaller and drooping, yet they are larger than those of any other animal.[4] There is also an animal which lives in the trees, feeds upon fruits, and carries its young in a pouch in the belly; no writer as far as I know has seen it, but I have already sufficiently described it in the Decade which has already reached Your Holiness before your elevation, as it was then stolen from me to be printed. [Note 3: It is hardly necessary to say that there were no lions or tigers in America. Jaguars, panthers, leopards, and ocelots were the most formidable beasts of prey found in the virgin forests of the New World.] [Note 4: This puzzling animal was the tapir.] It now remains for me to speak of the rivers of Uraba. The Darien, which is almost too narrow for the native canoes, flows into the Gulf of Uraba, and on its banks stands a village built by the Spaniards. Vasco Nuñez explored the extremity of the gulf and discovered a river one league broad and of the extraordinary depth of two hundred cubits, which flows into the gulf by several mouths, just as the Danube flows into the Black Sea, or the Nile waters the land of Egypt. It is called, because of its size, Rio Grande. An immense number of huge crocodiles live in the waters of this stream, which, as we know, is the case with the Nile; particularly I, who have ascended and descended that river on my embassy to the Sultan.[5] [Note 5: See _De Legatione Babylonica_.]
