Of the early institutions of Kongo we know next to nothing, though we may presume that the law of succession was originally the same there as in the sister-states to the north, for the first Ntotela was succeeded by two nephews (Nanga kia ntinu and another, whose name has not reached us). But even thus early, and anterior to the introduction of Christianity, the old law of succession was broken through, for Nkuwu a ntinu, the fourth Ntotela, was a son of Ntinu Nimi a Lukeni, and was succeeded by a son of his own, Nzinga a Nkuwa, the first Christian Ntotela, better known in history as John I. If Dapper may be believed, it was the custom to bury twelve virgins with the earlier kings—a distinction much sought after, as in other parts of Africa; but the people of Kongo have never been charged with cannibalism, nor its rulers with the bloody rites practised by the Jaga. CÃO’S DISCOVERY OF THE KONGO, 1482.[298] It was towards the end of 1482, that the natives at the mouth of the River Kongo for the first time saw rising above the horizon the white wings of a European vessel, ascending, as it were, from the Land of Spirits; and we can imagine their surprise when they for the first time beheld the bleached faces of its inmates. Yet they came on board, offering ivory in exchange for cloth. The interpreters from the Guinea coast who were with Cão naturally failed to make themselves understood, but they learnt from signs that far inland there dwelt a powerful king. Cão at once despatched some Christian negroes in search of this potentate. They were the bearers of suitable presents, and were instructed to assure the King of the friendly intentions of his visitors, whose only desire it was to trade with him. Before continuing his voyage, Cão set up the first of the stone pillars, or _padroes_, which he had on board. He then sailed south along the coast, noting its prominent features, but curiously missed the Kwanza or River of Angola, although its clayey waters discolour the sea for ten or fifteen miles. On a low foreland, Cabo do Lobo,[299] ten miles beyond the cliffs named by him Castello d’Alter Pedroso, he set up a second pillar, to mark the furthest point reached by him. On again returning to the Kongo, he was annoyed to find that his messengers had not returned; and as he was naturally anxious to make known in Portugal his discovery of a magnificent river and a powerful kingdom, he left them behind him, and seized instead four unsuspecting visitors to his ship as “hostages;” giving their friends to understand that they should be restored to them after the lapse of fifteen months, when they would be exchanged for his own men. These latter appear to have been treated with distinction at first, but when the King heard of Cão’s high-handed proceedings he refused to admit them any longer to his presence, and even threatened them with death, should his own people not be restored.
