In Maps of the Imagination, Peter Turchi posits the idea that maps
help people understand where they are in the world in the same way that
literature, whether realistic or experimental, attempts to explain human
realities. The author explores how writers and cartographers use many of
the same devices for plotting and executing their work, making crucial
decisions about what to include and what to leave out, in order to get
from here to there, without excess baggage or a confusing surplus of
information. Turchi traces the history of maps, from their initial
decorative and religious purposes to their later instructional
applications. He describes how maps rely on projections in order to
portray a three-dimensional world on the two-dimensional flat surface of
paper, which he then relates to what writers do in projecting a literary
work from the imagination onto the page.
