Between the two World Wars, painting lost some of the raw, modern energy
it began the century with and became dominated by two rather philosophical
which arose partly as a reaction to the senseless atrocities of World War I.
But artists were also becoming introspective, concerned with their own
subconscious dreams: Sigmund Freud's psychoanalytical theories were well
known by this time, and painters explored their own irrationalities
and fantasies in search of a new artistic freedom.
