Quotation from: The Gods of Mars

Written by: Edgar Rice Burroughs

There was little of disrespect in the tone that the man used in
addressing either Xodar or myself. It was evident that he felt
less contempt for the former Dator since he had witnessed the ease
with which I disposed of the powerful Thurid.

That his respect for me was greater than it should have been for a
slave was quite apparent from the fact that during the balance of
the return journey he walked or stood always behind me, a drawn
short-sword in his hand.
