After Cão's return, King John renewed his efforts with fresh energy. Already, in 1484, a negro embassy to Portugal had brought such an account of an inland prince, one "Ogane, a Christian at heart," that all the Court of Lisbon thought he must be the long lost Prester John, and men were sent out to seek this "great Catholic Lord" by sea and land. Bartholemew Diaz sailed in August 1486, with two ships, to try his fortune by the sea-route, and even if he could not reach the Prester's country, to discover as far as possible on the "way round Africa." Two other envoys, Covilham and Payva, were sent out by way of "Jerusalem, Arabia, and Egypt," to find the Priest-King and the Indies; yet another expedition was to ascend the Negro Nile, or Senegal, to its supposed junction with the Nile of Egypt; a fourth party started to explore a road to Cathay by the North-East Passage. Bartholemew Diaz, accompanied by João Iffante, rounded the southernmost point of Africa, and passed some way beyond the site of the modern Port Elizabeth. The picturesque story of his voyage is well known. He sailed with two vessels of 50 tons apiece, in the belief that "ships which sailed down the coast of Guinea might be sure to reach the end of the land by persisting to the South." His first pillar was set up at Angra dos Ilheos,[56] at the south side of Angra Pequena. He made another stay at Angra das Voltas, in 29° S. lat., immediately after passing the Orange River. Then, putting well out to sea, Diaz ran thirteen days due south before the wind, hoping by this wide sweep to round the furthest point of the Continent, which many traditions agreed in fixing not very far from his last halting-place. Finding the sea and air at last becoming cold, he changed his course to east, and as no land appeared after five days, to north. In this last course the Portuguese reached a bay where cattle were feeding, named by the Portuguese Angra dos Vaqueiros, now Flesh Bay.[57] After putting ashore two natives (probably some of those lately carried from Congo to Portugal, and sent out again to act as scouts for the European explorers), Diaz continued east to a small island still called "Santa Cruz," W. of our Port Elizabeth, and even further to a river called, after his partner, Rio do Iffante, now the Great Fish River, in 32° 23' S. lat., and midway between the present Port Elizabeth and East London, where the coast begins gradually but steadily to trend north-east. Here the expedition put back, sighting on its homeward way the Land's End, or "Cape of Storms," re-named by John II "Cape of Good Hope" on their return. Almost at the same time as Diaz' reappearance in Lisbon (Dec. 1487), Covilham, who had reached Malabar by way of Egypt, wrote home from Cairo more than confirming the hopes already drawn from the success of the last maritime ventures. "If you keep southward, the continent must come to an end. And when ships reach
