In Portugal's short span of empire, her day of brief and troubled splendour, her monarchs realize, even at the hazard of a temporary eclipse of the nation's independence, the aspirations of the race, which slowly arising, and growing in force and intensity, had become the fixed, tyrannous desire of a people, until, in Camoens' terse phrase of Manuel, "from that one great thought it never swerved." Another policy and other aims than those which her monarchs pursued--tolerance instead of fanaticism, prudence instead of heroism, national patriotism instead of imperial, homely common sense instead of glorious wisdom--all or any of these might have warded off the doom of Portugal and of the house of Avis. Bur these things were not in the blood of Lusitania, nor would this have been the nation of Vasco da Gama and Camoens, of Alboquerque and Cabral. It is as vain to seek in depopulation for the causes of the fall of Portugal as in the Inquisition or the Papal power. Even Buckle, that mighty statistician, would hardly risk the determining of the ratio which may not be overstepped between the bounds of an empire and the extent of the nation which creates it. If her yeomen forsook the fields and left the soil of Portugal unfilled, if her chivalry forsook their estates, the question confronts us: What is the character, the heart of a race which acts in this manner? What is the ideal powerful enough to make the hazard of a nation's death preferable to the abandonment of that ideal? The nation which sent its bravest to die at Al-Kasr al Kebir[11] is not a nation of adventurers. Nor do the instances of Phocaea, of the Cimbri, or the Ostrogoths afford any analogy here. Dom Sebastian's device fits not only his own career but the history of the race of which at that epoch he was at once the king and the ideal hero--"A glorious death makes the whole life glorious." And the genius of the nation sanctioned his life and his heroic death. To Portugal Dom Sebastian became such a figure as Frederick Barbarossa, dead on the far-off crusade, had been to the Middle Age, and for two centuries, whenever night thickened around the fortunes of the race, the spirit of Dom Sebastian returned to illumine the gloom, showing himself to a few faithful ones; and in very truth the spirit of his deeds and of their fathers never died in the hearts of the Portuguese, inspiring whatever is memorable in their later history.
