But nothing as yet foreshadowed the kind of spiritual influence there portrayed--that which, instead of making its way through the impact of character upon character, passion upon passion, is communicated through an unconscious glance or a song.

For one who believed as fixedly as Browning in the power of these moments to change the prevailing bias of character and conduct, such a conception was full of implicit drama.

A chance inspiration led him to attempt to show how a lyric soul flinging its soul-seed unconsciously forth in song might become the involuntary _deus ex machina_ in the tangle of passion and plot through which she moved, resolving its problems and averting its catastrophes.
The result was a poem which Elizabeth Barrett "could find it in her heart to envy" its author, which Browning himself (in 1845) liked better than anything else he had yet done.[17] It has won a not less secure place in the affections of all who care for Browning at all.

It was while walking alone in a wood near Dulwich, we are told by Mrs Orr, that "the idea flashed upon him of some one walking thus through life; one apparently too obscure to leave a trace of his or her passage, yet exercising a lasting though unconscious influence at every step of it; and the image shaped itself into the little silk-winder of Asolo."[18] The most important effect of this design was to call out Browning's considerable powers of rendering those gross, lurid, unspiritualised elements of the human drama upon which Pippa was to flash her transforming spell.

His somewhat burly jocosity had expatiated freely in letters; but he had done nothing which, like the cynical chaff of his art students, suggests the not unskilful follower of Balzac and Dickens.
And he had given no hint of the elemental tragic power shown in the great Ottima and Sebald scene, nor of the fierce and cruel sensuality, the magnificence in sin, of Ottima herself.
