It is but fair to mention that many authors have held these great discoveries to be merely re-discoveries. Some people affirm that Madeira was really discovered by Emmanuel Pessanha, the first Lord High Admiral of Portugal, in 1351, during the reign of Affonso “the Brave,” and there seems to be more foundation for the story of Robert Machin, which is at all events of great antiquity. The story runs that Robert Machin, son of a merchant in Bristol, loved and was beloved by a lady of noble birth, whose relations refused to countenance him, and threw him into prison. About the year 1370, on his release, he found that his lady love had married a wealthy baron, but he continued his suit and she consented to elope with him. He took her on board a ship intending to go to France, but a gale came on and the ship, after being driven south for thirteen days, struck upon an island. They found the island uninhabited and very beautiful, and Machin and some of his companions took up their residence upon it, and built huts under the branches of a spreading tree. Here they lived very happily until a storm one day drove the ship from its moorings, which so grieved the lady that she died in despair at the thought of never seeing her native land again. She was buried beneath the tree, and Machin soon followed her to the grave, having first erected a cross with a brief inscription, narrating his adventures, and begging any Christians who might come to the island to erect a church over the place where her remains rested. After his death, those of his companions, who remained, determined to try to escape in the ship’s boat, but they were taken by a Moorish cruiser and sold for slaves. While in captivity in Morocco, one of the Englishmen told a Spanish fellow-captive, named Juan Morales, the whole history, and this Morales, being afterwards taken prisoner by João Gonçalves Zarco, related the narrative to his captor and to Prince Henry. Morales, according to this tale, was the pilot of Zarco and Tristão Vaz on their voyage of discovery, and the story goes on to say that the grave of the two English lovers was discovered, and that Machin’s dying desire was fulfilled, and a church erected over their remains. Whatever may be the truth of this legend, and whether Machin ever landed on Madeira or not, the fact remains that the first occupation of the island, and its being marked upon the chart, were due to the enterprise of Prince Henry.

The discovery of these islands formed no part of Prince Henry’s plan. His desire was to circumnavigate Africa; the expeditions of Perestrello, Zarco, and Tristão Vaz were all intended to sail south and double Cape Bojador, and it was certainly in an attempt to achieve this purpose that Perestrello was driven out to sea to the island of Porto Santo. Many years passed, during which Cape Bojador remained the great obstacle to the Portuguese mariners. Year after year Prince Henry despatched fleets of two or three ships at a time, which sometimes made important discoveries among the islands off the north-west coast of Africa, but they never doubled the great cape. Among these discoveries the most important were the Canary Islands and the Azores. With regard to the former group, the Portuguese were met by a prior claim on the part of Castile; and after a dispute, into the details of which it is not necessary to enter, John the Great, in pursuance of his consistent policy of maintaining peace with Spain, and at the request of Dom Henry, who did not wish to waste his strength in occupying islands, surrendered the Canary Islands to Castile. The Portuguese, however, successfully maintained their claim to the Azores, which still belong to them. This group was first touched at by Bartholomeu Perestrello, the discoverer of Porto Santo, in 1431; and in the following year Gonçalo Velho Cabral discovered the island of Santa Maria. To this captain was allotted the task of further exploring and occupying this cluster of islands; and in 1444 he discovered the island of St. Miguel or St. Michael, where he founded the beautiful little town which gives its name to the St. Michael oranges.

Prince Henry’s endeavours were crowned with partial success, though not in the reign of his father, for in 1434 Gil Eannes doubled Cape Bojador, and in 1436 Affonso Gonçalves Baldaya reached the Rio d’Ouro. The attention of “the Navigator” was, however, soon absorbed by the progress of political affairs at home, and he had for a time to abandon his schemes of exploration. He served with distinction in the unfortunate expedition to Tangier, and then played an important part in the events, which ended in confirming the power of his brother Dom Pedro, the Duke of Coimbra, as Regent of Portugal. This enlightened prince took the greatest interest in the African explorations, and he assisted Prince Henry with even greater ardour than King John or King Edward. These were the most successful years of Prince Henry’s career. In 1441 Antão Gonçalves went a hundred leagues further than the Rio d’Ouro, and in the same year Nuno Tristão, the greatest and most daring of all Prince Henry’s captains, reached the cape which closes on the south the sort of shoulder formed by North-west Africa, and named it the Cabo Branco or White Cape. He did more than this; he brought home several captives, including a native prince. The capture was hailed with enthusiasm, and from this time the slave trade on the coast of Africa really began.

It is strange that Prince Henry “the Navigator” should have been the founder of the African slave trade, but so it was, and the reasons are not hard to find. The provinces of the Alemtejo and the Algarves had never been thoroughly populated since their conquest, and the great lords and religious military orders, the owners of those districts, had never been able to bring them properly under cultivation. Slavery was not regarded with the modern sentiment of abhorrence; it was the natural fate of prisoners of war, and flourished greatly in the neighbouring country of Morocco. Prince Henry and the Duke of Coimbra felt the need of procuring labour to cultivate the southern provinces, and it seemed quite natural to them to carry off the unfortunate savages of the African coast. This idea greatly impressed the Portuguese nobles with Prince Henry’s sagacity; they did not understand his schemes about discovering a direct route to India, but they highly appreciated the introduction of cheap forced labour. The commencement of the slave trade greatly favoured the progress of the Portuguese navigators; they no longer came home empty-handed, and exploring became a profitable as well as an adventurous business. In 1444 Lançarote, with a fleet of eight ships, went upon a slave-taking expedition, and brought home two hundred captives, who were set to work on the domains of the Order of Christ in the Algarves, and in 1445 the same captain sailed with a fleet of fourteen ships from Lagos and brought home a still larger body of unfortunate slaves. From this time forth the tracks made by the explorers were followed closely by the slave-dealers. Large profits were made in the trade, which had its centre at Lagos, and by the labour of the captives the great estates of southern Portugal were speedily brought under cultivation. The employment of slave labour was to have serious consequences in the near future; but at this period, during the life of Dom Henry, it had not yet begun to drive the poorer class of the Portuguese people out of work in the fields, and into more precarious modes of earning a livelihood.

It is not necessary to do more than notice the commencement of the slave trade here; it is far more important to trace the progress of the explorers.[10] In 1445 Nuno Tristão sailed as far as the Senegal river, and in the same year, Diniz Dias, his most daring rival, discovered Guinea, and first saw the really black negroes. This advance, as a glance at the map will show, meant much; the Portuguese explorers had now thoroughly learnt how to find their way round the inhospitable shoulder of North-west Africa; Cape Bojador and Cabo Branco had no terrors for them, and their hopes of reaching India were excited by finding that the coast trended abruptly to the east. The country, too, was very different to that which they had toiled around so slowly; the fertile land of Guinea with its powerful negroes, its spices and ivory, and its prospect of gold, gave them encouragement, and on their return, the acute merchants of Lisbon were not long in opening up a trade with the newly-discovered country. Unfortunately the slave trade accompanied the ventures of the Lisbon merchants, and the white men, instead of making friends with the blacks, did not hesitate to seize them and to sell them into slavery. The Church made no effort to restrain this traffic; the blacks were heathen, and so it was to their advantage to be brought to a Christian land to work, and perhaps to be converted.

The next two years were marked by the greatest activity. In 1446 Diniz Diaz reached Cape Verde, which he called by that name from its green appearance; and in the same year, Nuno Tristam was killed in a chase after slaves, and Alvaro Fernandes, the nephew of João Gonçalves Zarco, who had discovered Madeira, starting from that island, went one hundred leagues further than Cape Verde, and left João Fernandes at his own request among the negroes. It is a strange commentary upon the death of Nuno Tristão, that João Fernandes was able to remain among the negroes for seven months in safety, learning their language and studying their customs. It shows that there was no deep-rooted antipathy between the whites and the blacks, and that the latter only attacked the Christians, when they showed themselves enemies, and tried to rob them of their liberty. João Fernandes was taken off in safety by Antam Gonçalves, in the year 1447, and testified to Prince Henry that the blacks, if heathen, were not monsters, but people of peaceful and affectionate dispositions.

This activity was followed by another pause. Dom Henry was deeply affected by the overthrow of his brother Dom Pedro; and his nephew, Affonso V., failed to give him the moral and material support he had formerly received. It is indeed a blot upon the reputation of “the Navigator” that he made no greater effort to assist the great regent, and that he was not by his side at Alfarrobeira. The next decade is marked only in the history of maritime exploration by the discoveries of Luigi Cadamosto, a Venetian, who had entered the service of Dom Henry, and who had become his right hand both as a cartographer and an explorer. On the voyages of Cadamosto there has been much controversy. Some writers, resting upon certain notes of his, assert that he discovered the Gambia as early as 1445, and the Cape Verde Islands in 1446; but modern inquirers believe that he greatly antedated his discoveries in order to enhance his own glory. It is now generally believed that in his famous voyage in 1455 and 1456 he managed to get past the Senegal, and discovered the Gambia, and that the Cape Verde Islands were discovered in 1460 by Diogo Gomes. The tale that Cadamosto went as far as the Rio Grande is quite discredited, and seems in itself, apart from the evidence, to be most improbable.


The period of the discoveries made under the direction and inspiration of Prince Henry “the Navigator” was then at an end, for he died at Sagre on November 13, 1460. What he had done appears better from a study of the map then in any number of words. He had not discovered a direct sea route to India, but he had paved the way for it, and it was quite certain that, if it existed, the gallant captains trained by him would find the route in time. His services are beyond dispute, and though he left no successor to carry on the work, he had given it such an impulse, that it remained only for the sailors themselves to complete it. He was never married, but was succeeded as Duke of Viseu, Lord of Beja and Madeira, and Grand Master of the Order of Christ, by his nephew, Dom Ferdinand, the second son of King Edward, and brother of Affonso V., whom he had adopted. This prince had also become Grand Master of the Order of Santiago by his marriage with his first cousin, Donna Leonor, daughter of Dom John, the fourth son of John “the Great,” by whom he was father of Dom Manoel, or Emmanuel, who reigned under the title of Emmanuel “the Fortunate,” and was to reap the fruits of the discoveries of Vasco da Gama and Pedro Alvares Cabral.
