That difficulty, to which we have referred, of surmising how there could have remained material to fill out a poem on the Titanomachia which had begun with the Titans, all but one, dethroned already, seems to increase when we consider the above speech of Oceanus, setting forth with resigned prophetic wisdom the fated necessity of their fall. It increases still further when Clymene, following on the same side as Oceanus, tells how she has heard the strains of a new and ravishing music from the lyre of Apollo which have made her cast away in despair the instrument of her own formless music, the sea-shell; and still further again when in the next book we witness the meeting of Apollo with the Titaness Mnemosyne, mother of the Muses, who for his sake has 'forsaken old and sacred thrones,' and when we hear him proclaim how in the inspiration of her presence, Knowledge enormous makes a God of me. Names, deeds, grey legends, dire events, rebellions, Majesties, sovran voices, agonies, Creations and destroyings, all at once Pour into the wide hollows of my brain, And deify me, as if some blithe wine Or bright elixir peerless I had drunk, And so become immortal. Before the glory of this new-deified Apollo, what could long have delayed the defeat or abdication of the elder sun-god Hyperion?--what could have remained for Keats to invent that should have much enriched or lengthened out his poem? The sense of the difficulty of sustaining the battle of the primeval powers against these new and nobler successors may well have been one of the things (even had he not had Milton's comparative failure with the warfare in heaven to warn him) that hindered his going on with his poem. To the reader there occurs another and even greater difficulty: and that is that Keats had already given to his fallen elder gods or Titans so much not only of majesty but of nobleness and goodness that it is hard to see wherein he could have shown their successors excelling them. He had represented Saturn as wroth, indeed, at his downfall, but chiefly because it leaves him --smother'd up, And buried from all godlike exercise Of influence benign on planets pale, Of admonition to the winds and seas, Of peaceful sway above man's harvesting, And all those acts which Deity supreme Doth ease its heart of love in. Increase of knowledge, of skill in the arts of life and of beauty, the gods of the new dynasty might indeed extend to mankind, but what increase of love and beneficence? Even the relations of Saturn to his father Coelus (the Greek Uranus), which in the ancient cosmogony are of the crudest barbarity, Keats in _Hyperion_ makes benignant and sympathetic.
