Water. Earth. Fire. Air. These are just some of the elements and environments that video game avatars—the images representing and controlled by players—have faced since the days of Space Invaders, to say nothing of today's Pandora’s box of assorted baddies. Avatar comes from the Sanskrit word avatāraḥ, meaning “descent.” When avatar first appeared in English in the late 18th century, it referred to the descent of a deity to the earth—typically, the incarnation in earthly form of Vishnu or another Hindu deity. It later came to refer to any incarnation in human form, and then to any embodiment (such as the embodiment of a concept or philosophy), whether or not in the form of a person. All of these senses of avatar are still in use today, joined by the more recent computing/gaming sense, which may refer to “you” embodied as a mustachioed Italian plumber, for example, even if you are not, in fact, a mustachioed Italian plumber.
