Red // Light

Then  the  sun,

setting behind the houses,

pointed as though with a finger

at everything red in the street --

the red tops of the dragoons’ caps,

a red flag trailing on the ground,

and the red specks and threads

   of blood on the snow.

-- Boris Pasternak, Doctor Zhivago
(1957; transl. Hayward & Harari)
