Themis is the Greek goddess of divine justice. Her statue (mostly shown in movie-courts) shows her holding the scales in the left hand, a sword in the right hand. She is blind folded with a black ribbon. What the scales and sword symbolise ?

The traditional visual symbol of "Justice" is a blindfolded woman holding scales and a sword. The scales are for weighing right and wrong; the sword is to punish the guilty; the blindfold is to show that she is impartial (i.e. that she does not treat friends differently from strangers, or high-ranking people better than humble ones, because she does not "see" them). But she is not deaf, because she listens to all the evidence put before her.
