The first mirrors used by people were most likely pools of dark, still water. The myth of Narcissus is directly concerned with an element of human experience, as the word Narcissus indicates—narcosis, numbness or alienation. In the myth, Narcissus mistook his own reflection in the water for another person. This seductive doubling numbed his perceptions until he became the servomechanism of his own extended or repeated image.

The single-channel video, Marked by Mercury, explores this relationship with the gaze. A girl is depicted walking through a wooded landscape only to confront a mirror and becomes submerged and trapped in its watery dimension.
