The seen, the known
dissolve in iridescence, become
illusive flesh of light
that was not, was, forever is.

O LIGHT BEHELD AS THROUGH REFRACTING TEARS.
Here is the aura of that world
each of us has lost.
Here is the shadow of its joy.

–“Monet’s ‘Waterlilies,’”
Robert Hayden

How does the line in caps simile add meaning to the poem?

It explains why Monet painted this scene.
It creates imagery that appeals to hearing.
It describes the use of light in the painting.
It connects back to a historical event.
