Paul Léon was murdered in 1942, 

In Auschwitz concentration camp, 

Oświęcim, Poland.

A Jew, he was Joyce's friend,

The Joyce of Dublin & Galway,

Trieste, Zurich & Paris

And, off course, Anna L'Liffey,

She who riverrun on & on,

Even till the Finnegans' wake.

Joyce lived in Paris for twenty years

He was so poor but everytime he had money

He always paid for everyone in every bar,

Every taxi, every restaurant.

Paul Léon heard Joyce's leery voice

Echo 

As he drank his white wine

On his day of Atonement.

And, like Molly,

Faithful sorry you was

At the ten year break

Between you two.

He returned to Paris

To sort out Joyce's papers,

After he was dead.

And the Gestapo arrested you in '42:

You ended your life

A shadow

Of that other dangerous, murdered Jew.
