Quotation from: The Chessmen of Mars

Written by: Edgar Rice Burroughs

"A daughter," he replied, "only a little younger than Carthoris,
and, barring one, the fairest thing that ever breathed the thin
air of dying Mars. Only Dejah Thoris, her mother, could be more
beautiful than Tara of Helium."

For a moment he fingered the chessmen idly. "We have a game on
Mars similar to chess," he said, "very similar. And there is a
race there that plays it grimly with men and naked swords. We
call the game jetan. It is played on a board like yours, except
that there are a hundred squares and we use twenty pieces on
each side. I never see it played without thinking of Tara of
Helium and what befell her among the chessmen of Barsoom.
Would you like to hear her story?"
