The Gods of Mars is a 1918 Edgar Rice Burroughs science fiction novel, the
second of his famous Barsoom series. It was first published in All-Story as a
five-part serial in the issues for January-May 1913. It was later published as
a complete novel by A. C. McClurg in September, 1918.
Throughout his novels, Burroughs uses the classic device of a fictional
Foreword or Preface that suggests that the contents of the following story
reflect true events.
