Lieutenant Gullivar Jones: His Vacation is a novel by Edwin Lester Arnold
combining elements of both fantasy and science fiction, first published in
1905. The last of Arnold's novels, its lukewarm reception led him to stop
writing fiction. It has since become his best known work, and is considered
important in the development of 20th century science fiction in that it is a
precursor and likely inspiration to Edgar Rice Burroughs's classic A Princess
of Mars (1911), which spawned the sword and planet genre. Ace Books reprinted
Arnold's novel in paperback in 1964, retitling it Gulliver [sic] of Mars. A
more recent Bison Books edition (2003) was issued as Gullivar of Mars, adapting
the Ace title to Arnold's spelling.
