the mounting summer, brilliant and ominous

A yellow-headed, gold-hammered, sunflower-lanterned
Summer afternoon: after the sun soared
All morning to the marble-shining heights of the marvelous blue
Like lions insurgent, bursting out of a great black zoo,
As if all radiance rode over and roved and dove
To the thick dark night where the fluted roots clutched and gasped
As if all vividness poured, out poured
Over, bursting and falling and breaking,
As when the whole ocean rises and rises, in irresistible, uncontrollable
    motion, shaking:
The roar of the heart in a shell and the roar of the sea beyond the
    concessions of possession and the successions of time's continual
    procession.
