Beckett fact no. 20.
I mentioned the poem 'Dortmunder' in my last post. Dortmunder's a beer, and here's a bottle of it.
In Molloy the hero consumes a bottle of Wallenstein lager when Gaber drops in on him, then worries about Father Ambrose smelling it on his breath and using it as an excuse to palm him off with an unconsecrated communion wafer.
There's no such lager as Wallenstein, but there is a play called Wallensteins Lager by Schiller. Coleridge translated it, and Verdi partly based La Forza del Destino on it. Though Beckett himself hated opera, as he tells us at the end of Proust.
