With great ingenuity this Greek realism is made the stepping-stone to a conception of immortality as un-Greek as that of the Incarnation is un-Semitic.  Karshish shrank intuitively from a conception which fascinated while it awed; to Cleon a future state in which joy and capability will be brought again to equality seems a most plausible supposition, which he only rejects with a sigh for lack of outer evidence:—­

     “Zeus has not yet revealed it; and alas,
      He must have done so, were it possible!”

The little vignette in the opening lines finely symbolises the brilliant Greek decadence, as does the closing picture in Karshish the mystic dawn of the Earth.  Here the portico, flooded with the glory of a sun about to set, profusely heaped with treasures of art; there the naked uplands of Palestine, and the moon rising over jagged hills in a wind-swept sky.

In was in such grave adagio notes as these that Browning chose to set forth the “intimations of immortality” in the meditative wisdom and humanity of heathendom.  The after-fortunes of the Christian legend, on the other hand, and the naive ferocities and fantasticalities of the medieval world provoked him rather to scherzo,—­audacious and inimitable scherzo, riotously grotesque on the surface, but with a grotesqueness so penetrated and informed by passion that it becomes sublime. Holy-Cross Day and The Heretic’s Tragedy both culminate, like Karshish and Clean, in a glimpse of Christ.  But here, instead of being approached through stately avenues of meditation, it is wrung from the grim tragedy of persecution and martyrdom.  The Jews, packed like rats to hear the sermon, mutter under their breath the sublime song of Ben Ezra, one of the most poignant indictments of Christianity in the name of Christ ever conceived:—­

     “We withstood Christ then?  Be mindful how
      At least we withstand Barabbas now! 
      Was our outrage sore?  But the worst we spared,
      To have called these—­Christians, had we dared! 
      Let defiance of them pay mistrust of Thee,
      And Rome make amends for Calvary!”

And John of Molay, as he burns in Paris Square, cries upon “the Name he had cursed with all his life.”  The Tragedy stands alone in literature; Browning has written nothing more original.  Its singularity springs mainly from a characteristic and wonderfully successful attempt to render several planes of emotion and animus through the same tale.  The “singer” looks on at the burning, the very embodiment of the robust, savagely genial spectator, with a keen eye for all the sporting-points in the exhibition,—­noting that the fagots are piled to the right height and are of the right quality—­

     “Good sappy bavins that kindle forthwith, ... 
      Larch-heart that chars to a chalk-white glow:”
