No wise forward look can ignore the possibility of many sorrows and the certainty of some. Hope has ever something of dread in her eyes. The road will not be always bright and smooth, but will sometimes plunge down into grim cations, where no sunbeams reach. But even that anticipation may be calm. "Thou art with me" is enough. He who guides into the gorge will guide through it. It is not a cul de sac, shut in with precipices, at the far end; but it opens out on shining tablelands, where there is greener pasture.
In 1491 the Inka ruled the greatest empire on earth. Bigger than Ming Dynasty China, bigger than Ivan the Great's expanding Russia, bigger than Songhay in the Sahel or powerful Great Zimbabwe in the West Africa tablelands, bigger than the cresting Ottoman Empire, bigger than the Triple Alliance (as the Aztec empire is more precisely known), bigger by far than any European state, the Inka dominion extended over a staggering thirty-two degrees of latitude""as if a single power held sway from St. Petersburg to Cairo.
