A rat crept softly through the vegetation Dragging its slimy belly on the bank While I was fishing in the dull canal On a winter evening round behind the gashouse Musing upon the king my brother’s wreck And on the king my father’s death before him. White bodies naked on the low damp ground And bones cast in a little low dry garret, Rattled by the rat’s foot only, year to year.
There's this conflict immediately with dry and wet with the rat and his slimy belly. Going into fishing, into a "dull" canal". With "damp ground" contrasted with "dry garret". These bodies come alive only when the rat comes by looking for food. Immediately coming back to the introduction of this line, the bodies are alluded to as vegetation. There is an unnatural time that is only commented on by year to year, and which king is mentioned. This family seems to be plagued to death.
