If you travel on London Underground, you have probably noticed Poems on the Underground. On several occassions I have taken note of a poem and looked it up later online.
Today it was Futility by Wilfred Owen (see here).
Apart from being a sad & poignant elegy for a fallen soldier in World War 1 it is also a memento mori for Owen himself, with just 5 published poems and killed one week before the Armistice. I guess this is what the Poems on the Underground is intended to do – to educate, expand horizons, encourage discovery. It certainly worked for me – I found all his poems and read his biography.
