Consists of a map with said concentric circles indicated, along with the title. Writer Rebecca Solnit observes, “On the maps the route of the walk is drawn in to suggest that the walking is drawing on a grand scale, that his walking is to the land itself as his pen is to the map, and he often walks straight lines, circles, squares, spirals.” – Wanderlust: A History of Walking.
