'Coming events cast their shadow before.'

I had a vision in the summer light? 
Sorrow was in it, and my inward sight 
Ached with sad images. The touch of tears 
Gushed down my cheeks:?the figured woes of years 
Casting their shadows across sunny hours. 
Oh, there was nothing sorrowful in flowers 
Wooing the glances of an April sun, 
Or apple blossoms opening one by one 
Their crimson bosoms?or the twittered words 
And warbled sentences of merry birds;? 
Or the small glitter and the humming wings 
Of golden flies and many colored things? 
Oh, these were nothing sad?nor to see Her, 
Sitting beneath the comfortable stir 
Of early leaves?casting the playful grace 
Of moving shadows in so fair a face? 
Nor in her brow serene?nor in the love 
Of her mild eyes drinking the light above 
With a long thirst?nor in her gentle smile? 
Nor in her hand that shone blood-red the while 
She raised it in the sun. All these were dear 
To heart and eye?but an invisible fear 
Shook in the trees and chilled upon the air, 
And if one spot was laughing brightest?there 
My soul most sank and darkened in despair!? 
As if the shadows of a curtained room 
Haunted me in the sun?as if the bloom 
Of early flow'rets had no sweets for me, 
Nor apple blossoms any blush to see? 
As if the hour had brought too bright a day? 
And little birds were all too gay!?too gay!? 
As if the beauty of that Lovely One 
Were all a fable.?Full before the sun 
Stood Death and cast a shadow long before, 
Like a dark pall enshrouding her all o'er, 
Till eyes, and lips, and smiles, were all no more!
