The name of this painting quotes a title of Ray Bradbury’s short story, that depicts a day on the Earth, more precisely August 4, 2026, without human beings, who probably vanished after the nuclear disaster. Bradbury in his story also quotes a poem by Sara Teasdale:

There will come soft rains and the smell of the ground, 
And swallows circling with their shimmering sound; 
And frogs in the pools singing at night, 
And wild plum trees in tremulous white;
Robins will wear their feathery fire, 
And not one will know of the war, not one 
Will care at last when it is done. 
Not one would mind, neither bird nor tree,
If mankind perished utterly; 
And Spring herself, when she woke at dawn
Would scarcely know that we were gone."

There is also a cartoon based on a Bradbury’s story, that terrified me when I was a child and scares me ever since.
