“There were brave men before Agamemnon,”—heroes before there was a Homer to sing them, says that prince of sensible poets, Horace. It is not less true that there were nations before history—communities, races, of which the eye of civilisation never caught a glimpse. In some cases, before the light of history broke in upon their seclusion, these old types of mankind, losing their individuality, had become merged in a succeeding and mightier wave of population; in others they had wholly disappeared,—they had lived and fought and died in perfect isolation from every focus of civilisation, and left not even a floating legend behind them in the world. Man’s mortality—the destiny of the individual to pass away from earth like a vapour, making room for others, heirs of his wisdom and unimbued with his prejudices—is the most familiar of truths; but the mortality of nations, the death of races, is a conception which at first staggers us. That a family should grow into a nation,—that from the loins of one man should descend a seed like unto the sands on the sea-shore for multitude, appears to our everyday senses as a natural consequence; but that nations should dwindle down to families, and families into solitary individuals, until death gets all, and earth has swallowed up a whole phase of humanity, is a thought the grandeur of which is felt to be solemn, if not appalling. The conception, however, need not be a strange one. Facts, which reconcile us to everything, are testifying to its truth even at the present day. It is not long since the Guanches in the Canary Islands, that last specimen of what may once have been a race, and the Guarras in Brazil, dwindled out of existence in their last asylum,—expiring at the feet of the more lordly race which the fulness of time brought to their dwellings.
