For the eye of the thinker, all historic murderers are to be found there, in that hideous penumbra, on their knees, with a scrap of their winding-sheet for an apron, dismally sponging out their work.
Victor Hugo
Les Misérables
At Stephen’s suggestion, at Bloom’s instigation both, first Stephen, then Bloom, in penumbra urinated, their sides contiguous, their organs of micturition reciprocally rendered invisible by manual circumposition, their gazes, first Bloom’s, then Stephen’s, elevated to the projected luminous and semiluminous shadow.
James Joyce
Ulysses
