Hernan Lopes de Castaneda.

Don John, the second of that name, and thirteenth king of Portugal, considering that all spices, drugs, precious stones, and other riches which came from Venice, were brought out of the east, and being a prince of great penetration, and high emprize, he was greatly desirous to enlarge his kingdom, and to propagate the knowledge of the Christian faith to distant regions. He resolved, therefore, to discover the way by sea to the country whence such prodigious riches were brought, that his subjects might thereby be enriched, and that his kingdom might acquire those commodities which had hitherto been brought by way of Venice. He was much encouraged to this enterprise, by learning that there were Christians in India, governed by a powerful monarch called Presbyter John, who was reported to be a Christian prince, and to whom he thought proper to send ambassadors, that an intercourse of friendship might be established between them and their subjects. He consulted, therefore, with the cosmographers of the time, whom he directed to proceed according to the example already given in sailing along the coast of Guinea, which had been formerly discovered by command of the prince his uncle, Master of the order of Christ. Accordingly, Bartholomew Diaz, one of the officers of the royal storehouse at Lisbon, was sent upon this expedition, who discovered that great and monstrous cape, now called of Good Hope, which was unknown to our ancestors. Finding it both terrible and dangerous, he yet passed 140 leagues beyond, to a river which he named Rio del Infante, whence he returned into Portugal. In this voyage, Diaz gave those names which they still retain, to the ports, harbours, and rivers where he took in fresh water, and erected certain marks, with crosses, and the royal arms of Portugal, the last of which was placed on a rock named El pennol de la Cruz, fifteen leagues on this side of the before mentioned river. Diaz returned from this voyage without having procured any intelligence concerning India, as all the inhabitants of the coast which he visited and discovered were ignorant black savages.

On the return of Diaz, king John resolved to attempt the discovery of India by land; for which purpose he had formerly sent friar Antonio de Lisboa by land, in company with a lay person; but as they were ignorant of the Arabic language, they could not travel into those parts, and went no farther than Jerusalem, whence they returned into Portugal, without having acquired any knowledge of the object of their journey. Yet the king continued to prosecute this discovery of India by land, for which he employed two of his own servants, Pedro de Covillian and Alonso de Payva, both versant in the Arabic language, who were instructed to search out the dominions of Presbyter John, and the country whence the spices and drugs were brought to Venice, and to inquire whether there were any navigation from the southern extremity of Africa to India. To these men he gave a chart, which was extracted from a map of the world, by Calsadilla, bishop of Viseo, an eminent astronomer. He gave them likewise a general letter of credit and safe conduct, requiring them to be assisted and protected, and supplied with money, in whatever kingdoms or countries they might travel; ordering them to receive 400 crowns from the chest of the orchard of Almeryn, for their charges. Of this sum, they took what they deemed necessary to bear their expences till their arrival at Valentia in Arragon, placing the rest in the bank of Bartholomew of Florence, to be repaid at Valentia.

Receiving their audience of leave from King John, in presence of Don Manuel, duke of Viseo, afterwards king, they departed from Santaxen on the 7th May 1487, and came to Naples on St Johns day of that year; whence they were forwarded by the sons of Cosmo de Medici, and went to Rhodes, and thence to Alexandria. From this place they travelled as merchants to Cairo, whence they went in company with certain Moors of Fez and Tremesen to Toro, a harbour on the Arabian coast of the Red Sea. They here learned many things respecting the Indies, and of the trade from the Red Sea to Calicut; and, going from Toro to a place on the coast of Ethiopia, they went to the port of Aden. The travellers here separated, Alonso de Payva passing over to the emperor of Ethiopia, erroneously called Presbyter John: For he, of whom Marco Polo speaks, under that title, as governing all the Indies, and whose country joins with the great khan of Kathay, was vanquished and slain in a battle by that sovereign; at which time his kingdom was put an end to, and no one of that race or title has since reigned. Yet Alonso de Payva actually believed that the emperor of Ethiopia was Presbyter John, having learnt that he was a Christian king over a Christian nation, as shall be more particularly declared hereafter. At their separation they agreed to meet again at Cairo, when each had executed his part of the royal orders.

Pedro de Covillian sailed from Aden for the Indies, in a ship belonging to the Moors of Cananor, and went to Calicut and the island of Goa, where he acquired complete information respecting the spices of India, the commodities which come from other places, and the towns of the Indies; the names of all which he inserted, but ill written, in his chart. From India he went to Sofala, where he procured information respecting the great island of St Lawrence, called the Island of the Moon by the Moors. Observing that the natives of Sofala were black, like those of Guinea, he concluded, that all the coast between was under subjection to the Negroes, and consequently that navigation was practicable from Guinea to Sofala, and thence to the Indies. Returning from Sofala, he went to Ormus, and thence to Cairo, where he learnt that Alonso de Payva was dead, and meant to have returned to Portugal. He chanced to meet at Cairo two Spanish jews, Rabbi Abraham, a native of Viseo, and Joseph, born in Lamego; who, after the departure of Covillian and Payva from Portugal, had told the king that they had been in Cairo, where they had received much information concerning Ormus, and of its trade with the Indies. From these Jews Covillian received letters from the king, directed to him and Payva, ordering them to return along with the Jews, if they had seen all that he had given them in charge. If they had not executed all his original instructions, they were now directed to send by the Jews an exact account of all the knowledge they had acquired, and to use their utmost efforts to visit Presbyter John, and to give all the information in their power respecting Ormus, to Rabbi Abraham, who had sworn by his law not to return to Portugal without visiting that place.

On receiving these letters, Covillian changed his intention of returning into Portugal, and dispatched Joseph there with letters to the king, giving an account of all that he had seen and learnt in India and Sofala, and transmitted the chart on which he had inserted all the places he had visited. In these letters he informed the king that the emperor of Ethiopia was assuredly the same with Presbyter John; but my opinion is that this is an error, as this sovereign has no such name in his own dominions, as I shall more clearly shew hereafter. On the departure of Joseph, Covillian and Rabbi Abraham went to Ormus, and thence back to the Red Sea; whence Covillian sent Abraham into Portugal, with letters to the king, containing all the information acquired in this part of the expedition, and intimating his determination to go into the dominions of Presbyter John. This he accordingly did, and came to the presence of the then emperor of Ethiopia, named Alexander, to whom he delivered the letters with which he had been entrusted by the king of Portugal for that monarch. Alexander received him courteously, and seemed much pleased with the letters of the king of Portugal, as being from so very distant a Christian prince, yet did not seem to attach much credit or importance to them. But he gave all honour, and many gifts to Covillian.
