320 A BRIEF SURVEY OF HUMAN HISTORY pioneers claimed a monopoly of exploitation of the new lands discovered by them, the reactions of which we shall describe in a later chapter. A Papal Bull confirmed their respective claims in 1493 : an imaginary line was drawn by Pope Alexander VI through the Atlantic, 300 miles west of the Azores and Cape Verde Islands, the East being the share of the Portuguese and the! Wast of the Spaniards. The Demarcation Line was shifted in 1494, 800 miles farther to the west, so that, in 1500, when Brazil was discovered by the Portuguese it was found to lie within their purview. Here we must digress a little to note the conditions of civilisation in the new continent. Mexico and Peru were conquered respectively by Cortez and Pizarro in 1519-21 and 1531-32, They were both adventurers who were prone to practise every type of villainy, " ignorant, fanatical, lustful of blood and gold," as Professor Hearnshaw has described them. Mexico and Peru were both seats of an ancient civili- sation "which seems to have had many affinities with the so-called ' hdiolithic' civilisation which prevailed in the Medi- terranean world some thousand years B.C. " The opportunity, writes Professor Hearnshaw, .was unique to gain an insight into ideas and institutions widely divergent from those of Christendom, but it was forever lost; for the savage in- vaders thought only to plunder, slay and destroy.1 One incident may be cited for illustration. Through treachery Pizarro made Atahualpa, the Inca leader, captive, and de- manded for his ransom a room full of gold ' as high as he could reach.' The demand was fulfilled, but not the pro- mise. Pizarro took both Atahualpa's gold and life. The Incas oŁ Peru were far advanced in civilisation. The great cities of their empire were filled with splendid palaces and 1.
