The Life and Voyages of Christopher Columbus (Volume II)

streams were supplied; that originally the Phison traversed Arabia Deserta and Arabia Felix, whence it pursued its course to the gulf of Persia; that the Gihon bathed northern or stony Arabia and fell into the Arabian Gulf or the Red Sea; that the Euphrates and the Tigris passed by Eden to Assyria and Chaldea, whence they discharged themselves into the Persian Gulf.
    By most of the early commentators the river Gihon is supposed to be the Nile. The source of this river was unknown, but was evidently far distant from the spots whence the Tigris and the Euphrates arose. This difficulty, however, was ingeniously overcome by giving it a subterranean course of some hundreds of leagues from the common fountain, until it issued forth to daylight in Abyssinia. [396] In like manner, subterranean courses were given to the Tigris and the Euphrates, passing under the Bed Sea, until they sprang forth in Armenia, as if just issuing from one common source. So also those who placed the terrestrial paradise in islands, supposed that the rivers which issued from it, and formed those heretofore named, either traversed the surface of the sea, as fresh water, by its greater lightness, may float above the salt; or that they flowed through deep veins and channels of the earth, as the fountain of Arethusa was said to sink into the ground in Greece, and rise in the island of Sicily, while the river Alpheus pursuing it, but with less perseverance, rose somewhat short of it in the sea.
    Some contended that the deluge had destroyed the garden of Eden, and altered the whole face of the earth; so that the rivers had changed their beds, and had taken different directions from those mentioned in Genesis; others, however, amongst whom was St. Augustine, in his commentary upon the book of Genesis, maintained that the terrestrial paradise still existed, with its original beauty and delights, but that it was inaccessible to mortals, being on the summit of a mountain of stupendous height, reaching into the third region of the air, and approaching the moon; being thus protected by its elevation from the ravages of the deluge.
    By some this mountain was placed under the equinoctial line; or under that band of the heavens metaphorically called by the ancients “the table of the sun,” [397] comprising the space between the tropics of Cancer and Capricorn, beyond which the sun never passed in his annual course. Here would reign a uniformity of nights and days and seasons, and the elevation of the mountain would raise it above the heats and storms of the lower regions. Others transported the garden beyond the equinoctial line and placed it in the southern hemisphere; supposing that the torrid zone might be the flaming sword appointed to defend its entrance against mortals. They had a fanciful train of argument to support their theory. They observed that the terrestrial paradise must be in the noblest and happiest part of the globe; that part must be under the noblest part of the heavens; as the merits of a place do not so much depend upon the virtues of the earth, as upon the happy influences of the stars and the favorable and benign aspect of the heavens. Now, according to philosophers, the world was divided into two hemispheres. The southern they considered the head, and the northern the feet, or under part; the right hand the east, whence commenced the movement of the primum mobile, and the left the west, towards which it moved. This supposed, they observed that as it was manifest that the head of all things, natural and artificial, is always the best and noblest part, governing the other parts of the body, so the south, being the head of the earth, ought to be superior and nobler than either east, or west, or north; and in accordance with this, they cited the opinion of various philosophers among the ancients, and more especially that of Ptolemy, that the stars of the southern hemisphere were larger, more resplendent, more perfect, and of course of greater virtue and efficacy, than those of the northern: an error universally prevalent until disproved by modern discovery. Hence they concluded that in this southern hemisphere, in this head of the earth, under this purer and brighter sky, and these more potent and benignant stars, was placed the terrestrial paradise.
    Various ideas were entertained as to the magnitude of this blissful region. As Adam and all his progeny were to have lived there, had he not sinned, and as there would have been no such thing
