Robert Ervin Howard,
The Mirrors of Tuzun Thune
(1929)
“ This is beyond my understanding, since first I saw him in the still waters of the lakes of Atlantis, till I saw him again in the gold-rimmed mirrors of Valusia. He is I, a shadow of myself, part of myself—I can bring him into being or slay him at my will; yet"—he halted, strange thoughts whispering through the vast dim recesses of his mind like shadowy bats flying through a great cavern—"yet where is he when I stand not in front of a mirror? May it be in man's power thus lightly to form and destroy a shadow of life and existence? ”
