Quotation from: The Gods of Mars

Written by: Edgar Rice Burroughs

"Two from the outer world are at large within the dominions of the
therns. We sought them at the command of the Father of Therns.
One was white with black hair, the other a huge green warrior,"
and here the fellow cast a suspicious glance toward Tars Tarkas.

"Here, then, is one of them," spoke Thuvia, indicating the Thark,
"and if you will look upon this dead man by the door perhaps you
will recognize the other. It was left for Sator Throg and his
poor slaves to accomplish what the lesser therns of the guard were
unable to do--we have killed one and captured the other; for this
had Sator Throg given us our liberty. And now in your stupidity
have you come and killed all but myself, and like to have killed
the mighty Sator Throg himself."
