The third voyage began May 30, 1498, and embraced six vessels and 200 men. Columbus struck southwestward from the Cape Verde Islands and ran nearly to the equator, into a region of torrid heat, discovering Trinidad, Tobago, Grenada, and the Gulf of Paria, and making his first landing on the continent, at the Pearl Coast, near the mouth of the Orinoco, in what is now Venezuela. This voyage witnessed many disasters--the rebellion of Roldan, the severe prostration of the admiral by fever, and his seizure and imprisonment in chains by the infamous Bobadilla. The fourth and last voyage of Columbus, with four small caravels and 150 men, was begun May 11, 1502. On this voyage he discovered Martinique and the coasts of Honduras, Nicaragua, and Veragua, on the mainland, returning to Spain, after untold disasters and miseries, on November 7, 1504. Then followed the weary struggle of the infirm old voyager to secure justice and a part of his hard-earned benefits from the crown. But Isabella had died, and Ferdinand, under the influence of the hard-hearted and cruel bigot, Fonseca, postponed all the claims of Columbus. He who had given a world died in poverty, a suppliant for the means of an honorable existence. It is easy enough for the writers of the nineteenth century to criticise the actors of the fifteenth; and learned scholars, sitting in luxurious easy-chairs in great libraries, can pass swift and severe judgment upon the acts and motives of Columbus. But let them go back four hundred years, and divest themselves of the bias which the science of to-day unconsciously inspires; let them quit the age of steam-engines, telegraphs, democratic governments, printing-presses, and Sunday-schools; let them orient themselves, and become Spaniards of 1492, instead of Americans of 1892; let them take the place of Columbus--if they are gifted with imagination enough among their manifold endowments to do it; let them think his thoughts, endure his trials, cherish his resolves, encounter his rebuffs, overcome his obstacles, launch out on his voyage, govern his mutinous crew, deal with his savage and hostile tribes, combat the traitors in his camp, suffer his shipwrecks, struggle with his disappointments, bear the ignominy of his chains, see his visions, and pray his prayers.
