WWI poetry

I decided to read "Dead Cow Farm" by Robert Graves. I picked this poem in particular because I thought it was just a very interesting and unusual name for a poem. In the poem it describes a cow as the creator of Adam and Eve. I thought this was particularly interesting because that is not how I have always pictured the creation of Adam and Eve. At the end it says "the old cow's dead." I think when he says this he means that the off spring of the cow's creation are all dead like many of the men who died in WWI.
