The goal of ancient Egyptian art was to show the human body as complete as possible, and there were many artistic devices used to assure harmony. Many times, these images served a religious purpose. For example, portraits of the dead could help assure the survival of the soul in the afterlife if the mummy was destroyed.
Unfortunately for Robankhamun fans, there is only one surviving painting by the man. This painting was found in his tomb. Egyptologists imagine that the tomb decoration was started by a trained artist, but Robankhamun chose to paint his own portrait. Like other artists in the Liefeld family tree, this one chose to draw giant arms with bulging veins, a tiny head, and uneven legs. Most importantly, Robankahamun made a proud statement of his inability to draw feet.
