The Princess of Helium, granddaughter of the Jeddak of Helium,
Barsoom.
From the series of books
John Carter of Mars by
Edgar Rice Burroughs. She is the quintessential
SciFi princess. She is shapely, red-skinned, and
naked. She is at once delicate and indominable, cultured and barbaric.
Although slightly dated and scientifically inaccurate, ERB's tales of Mars and the lovely Dejah Thoris set the stage for decades of
Space Operas and introduced romance/sex to mainstream SciFi.
A Princess of Mars, the first book featuring Dejah Thoris, is available from
Project Gutenberg.
