What are the motifs in The Rings of Saturn by W.G. Sebald?

The motif of history and time is evident as the author makes his pilgrimage along the Suffolk coastline in the United Kingdoms. As he journeys, he encounters places and characters of interest both in the present day and from the past on his quest to understand both himself and his surroundings in their correct place in the passage of time and how they all relate to death.
