Quotation from: The Gods of Mars

Written by: Edgar Rice Burroughs

But it was not these inspiring and magnificent evidences of Nature's
grandeur that took my immediate attention from the beauties of
the forest. It was the sight of a score of figures moving slowly
about the meadow near the bank of the mighty river.

Odd, grotesque shapes they were; unlike anything that I had ever
seen upon Mars, and yet, at a distance, most manlike in appearance.
The larger specimens appeared to be about ten or twelve feet in
height when they stood erect, and to be proportioned as to torso
and lower extremities precisely as is earthly man.
