As to the idea of finding land by sailing directly to the West, it is at present so familiar to our minds, as in some measure to diminish the merits of the first conception, and the hardihood of the first attempt; but in those days, as has been well observed, the circumference of the earth was yet unknown; no one could tell whether the ocean was not of immense extent, impossible to be traversed; nor were the laws of specific gravity, and of central gravitation, ascertained, by which, granting the rotundity of the earth, the possibility of making the tour of it would be manifest."
Several years, however, elapsed before Columbus could make any progress towards carrying into effect his favourite project. He was himself too poor to render any pecuniary assistance towards the fitting out of the requisite expedition; and the government of Portugal was then too much engrossed in a war with Spain to engage the services of a foreigner in any peaceful enterprise of an expensive nature.
