Apparently the problem of heredity is too involved to stir him to attempted solution. If to make a gentleman one must begin with his grandfather, surely to make a poet one must begin with the race, and in poems even of such bulk as the _Prelude_ one does not find a complete analysis of the singer's forbears. In only one case do we delve far into a poet's heredity. He who will, may perchance hear Sordello's story told, even from his remote ancestry, but to the untutored reader the only clear point regarding heredity is the fusion in Sordello of the restless energy and acumen of his father, Taurello, with the refinement and sensibility of his mother, Retrude. This is a promising combination, but would it necessarily flower in genius? One doubts it. In _Aurora Leigh_ one might speculate similarly about the spiritual aestheticism of Aurora's Italian mother balanced by the intellectual repose of her English father. Doubtless the Brownings were not working blindly in giving their poets this heredity, yet in both characters we must assume, if we are to be scientific, that there is a happy combination of qualities derived from more remote ancestors. The immemorial tradition which Swinburne followed in giving his mythical poet the sun as father and the sea as mother is more illuminating, [Footnote: See _Thalassius_.] since it typifies the union in the poet's nature of the earthly and the heavenly. Whenever heredity is lightly touched upon in poetry it is generally indicated that in the poet's nature there are combined, for the first time, these two powerful strains which, in mysterious fusion, constitute the poetic nature. In the marriage of his father and mother, delight in the senses, absorption in the turbulence of human passions, is likely to meet complete otherworldliness and unusual spiritual sensitiveness. There is a tradition that all great men have resembled their mothers; this may in part account for the fact that the poet often writes of her. Yet in poetical pictures of the mother the reader seldom finds anything patently explaining genius in her child. The glimpse we have of Ben Jonson's mother is an exception. A twentieth century poet conceives of the woman who was "no churl" as A tall, gaunt woman, with great burning eyes, And white hair blown back softly from a face Etherially fierce, as might have looked Cassandra in old age.
