It was believed by the Dutch cosmographers that some ten thousand miles of voyaging might be saved, could the passage to what was then called the kingdoms of Cathay be effected by way of the north. It must be remembered that there were no maps of the unknown regions lying beyond the northern headlands of Sweden. Delineations of continents, islands, straits, rivers, and seas, over which every modern schoolboy pores, were not attempted even by the hand of fancy. It was perhaps easier at the end of the sixteenth century than it is now, to admit the possibility of a practical path to China and India across the pole; for delusions as to climate and geographical configuration then prevalent have long since been dispelled. While, therefore, at least as much heroism was required then as now to launch into those unknown seas, in hope to solve the dread mystery of the North; there was even a firmer hope than can ever be cherished again of deriving an immediate and tangible benefit from the enterprise. Plancius and Maalzoon, the States-General and Prince Maurice, were convinced that the true road to Cathay would be found by sailing north-east. Linschoten, the man who knew India and the beaten paths to India better than any other living Christian, was so firmly convinced of the truth of this theory, that he volunteered to take the lead in the first expedition. Many were the fantastic dreams in which even the wisest thinkers of the age indulged as to the polar regions. Four straits or channels, pierced by a magic hand, led, it was thought, from the interior of Muscovy towards the arctic seas. According to some speculators, however, those seas enclosed a polar continent where perpetual summer and unbroken daylight reigned, and whose inhabitants, having obtained a high degree of culture; lived in the practice of every virtue and in the enjoyment of every blessing. Others peopled these mysterious regions with horrible savages, having hoofs of horses and heads of dogs, and with no clothing save their own long ears coiled closely around their limbs and bodies; while it was deemed almost certain that a race of headless men, with eyes in their breasts, were the most enlightened among those distant tribes. Instead of constant sunshine, it was believed by such theorists that the wretched inhabitants of that accursed zone were immersed in almost incessant fogs or tempests, that the whole population died every winter and were only recalled to temporary existence by the advent of a tardy and evanescent spring. No doubt was felt that the voyager in those latitudes would have to encounter volcanoes of fire and mountains of ice, together with land and sea monsters more ferocious than the eye of man had ever beheld; but it was universally admitted that an opening, either by strait or sea, into the desired Indian haven would reveal itself at last.
