It is often hard to know how far back we should go in the ancestry of a man whose life and character we are trying to reconstruct. The life that is in him is not his own, but is mysteriously transmitted through the life of his parents; to the common stock of his family, flesh of their flesh, bone of their bone, character of their character, he has but added his own personality. However far back we go in his ancestry, there is something of him to be traced, could we but trace it; and although it soon becomes so widely scattered that no separate fraction of it seems to be recognisable, we know that, generations back, we may come upon some sympathetic fact, some reservoir of the essence that was him, in which we can find the source of many of his actions, and the clue, perhaps, to his character. In the case of Columbus we are spared this dilemma. The past is reticent enough about the man himself; and about his ancestors it is almost silent. We know that he had a father and grandfather, as all grandsons of Adam have had; but we can be certain of very little more than that. He came of a race of Italian yeomen inhabiting the Apennine valleys; and in the vale of Fontanabuona, that runs up into the hills behind Genoa, the two streams of family from which he sprang were united. His father from one hamlet, his mother from another; the towering hills behind, the Mediterranean shining in front; love and marriage in the valley; and a little boy to come of it whose doings were to shake the world.
