ABSTRACT
In order to understand the question, it must be premised that the whole globe of earth and water is divided into two equal parts or halves by the equinoctial line. The northern hemisphere, which stretches from the equinoctial to the Arctic Pole, contains all which has been hitherto discovered and peopled in Asia, Europe, and the chief part of Africa. The remaining half, or southern hemisphere, which reaches from the equinoctial to the Antarctic Pole, comprises part of what we call America, and the whole of that Austral land,
the discovery and apostolic conquest of which is now treated of. Now, if we except from this southern hemisphere all that there is of Africa lying between the equinoctial line and the Cape of Good Hope, and all that there is of Peru from the parallel of the said equinoctial line, which passes near Quito, down to the straits of Magellan^ and that small portion of land which lies to the south of the strait, all the rest of the firm land of the said southern hemisphere remains to be discovered. Thus of the whole globe, there is little less than one entire half which remains to be discovered, and to have the gospel preached in it; and this discovery and evangelical conquest .forms the principal part of the obligation under which these kingdoms lie for the preaching of the gospel to the gentiles, in conformity with the agreement made with the Catholic Church and its head, the supreme pontiffs Alexander VI and Paul III.
