And first, touching the name of this noble and mysterious stream. Diogo Cam, the discoverer in 1485, called it River of Congo, Martin von Behaim Rio de Padrao, and De Barros "Rio Zaire." The Portuguese discoveries utilized by Dapper thus corrupted to the sonorous Zaïre, the barbarous Nzadi applied by the natives to the lower bed. The next process was that of finding a meaning. Philippo Pigafetta of Vicenza,[FN#10] translated Zaïre by "so, cioè Sapio in Latino;" hence Sandoval[FN#11] made it signify "Rio de intendimiento," of understanding. Merolla duly records the contrary. "The King of Portugal, Dom John II., having sent a fleet under D. Diego Cam to make discoveries in this Southern Coast of Africa, that admiral guessed at the nearness of the land by nothing so much as by the complexion of the waters of the Zaire; and, putting into it, he asked of the negroes what river and country that was, who not understanding him answered ‘Zevoco,' which in the Congolan tongue is as much as to say ‘I cannot tell;' from whence the word being corrupted, it has since been called Zairo." D'Anville (1749), with whom critical African geography began, records "Barbela," a southern influent, perhaps mythical, named by his predecessors, and still retained in our maps: it is the Verbele of Pigafetta and the Barbele of Linschoten, who make it issue either from the western lake-reservoir of the Nile, or from the "Aquilunda" water, a name variously derived from O-Calunga, the sea (?), or from A-Kilunda, of Kilunda (?) The industrious compiler, James Barbot (1700), mentions the "Umbre," the modern Wambre, rising in the northern mountains or, according to P. Labat, in a lake: Dapper (1676), who so greatly improved the outline of Africa, had already derived with De Barros the "Rio Zaïre" from a central reservoir "Zaïre," whose island, the Zembre, afterwards became the Vambere, Wambre, and Zambere, now identified through the Zambeze with the Maravi, Nyassa or Kilwa water. The second or northernmost branch is the Bancora of modern maps, the Brankare of Pigafetta, and the Bancari of Cavazzi; it flows from the same mountain as the Umbre, and Duarte Lopez (1560) causes it to mingle with the Zaire on the eastern borders of Pango, at the foot of the Sierra del Crystal. In certain modern maps the Bankare fork is called "Lekure,"and is made to receive the "Bambaye." The Barbela again anastomoses with the Luba (?) or northern section of the Coango, including its influent, the Lubilash; the Kasai (Kasabi) also unites with the Coango, and other dotted lines show the drainage of the Lualaba into the Kasai.
