"So much depends on a red wheel-barrow"

The Red Wheelbarrow
William Carlos Williams

--------------------------------------------------------------------------------
so much depends
upon
a red wheel
barrow

glazed with rain
water

beside the white
chickens.
---------------------------------------------------------------------------------
I have always felt as if there is a subterranean and serious depth under the seemingly ordinary and playful surface of Williams' poem- a red wheel barrow, rain water and white chickens. After all, why does so much depend on the red wheel barrow? Especially when rain-water glazes it and white chickens gather around it?
The glass-like redness of the wheel-barrow probably appears pleasant to the eye when it lays beside the white chickens who might be "thinking" of small edible seeds and fruits in the wheel-barrow. The chickens probably do not like the rain and might be seeking shelter near the wheel-barrow. Is the "so much" that depends on the wheel-barrow then security and warmth on which depends the well-being of chickens who lay eggs for our well-being, the well-being of the wheel-barrow users? Is the poem about the interdependence and beauty in nature? One can also think about the interdependence among human farmers who probably have to share the red wheel-barrow? The red wheel-barrow built and used in unison? Colored red and placed beside the chickens as a work of art, not only to be used but also to be watched in a reflective spirit of admiration....
