When love takes possession of a nature which is complex, affluents and tributaries from many and various faculties run into the main stream.

With Browning the passion is indeed a regal power, but intellect, imagination, fancy are its office-bearers for a time; then in a moment it resumes all authority into its own hands, resolves of a sudden all that is complex into the singleness of joy or pain, fuses all that is manifold into the unity of its own life and being.

His dramatic method requires that each single faculty should be seen in the environment of a character, and that its operations should be clothed more or less in circumstance.

And since love has its ingenuities, its fine-spun and far-flung threads of association, its occult symbolisms, Browning knows how to press into the service of the central emotion objects and incidents and imagery which may seem remote or curious or fantastic or trivial or even grotesque.
In _Rudel to the Lady of Tripoli_ love which cometh by the hearing of the ear (for Rudel is a sun-worshipper who has never seen his sun) is a pure imaginative devotion to the ideal.

In _Count Gismond_ love is the deliverer; the motive of the poem is essentially that of the Perseus and Andromeda myth refined upon and mediaevalised.
