Justice is blind

What's the origin or meaning behind "justice is blind, not deaf"?

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.

That is an 'old wive's tale.' Justice is NOT blindfold.

In what sense not blindfold, DFG? There are innumerable images of Justice across the Western world where she is depicted blindfold. I agree that she is not invariably so (whereas she always has the sword and scales) and it is possibly a more recent development of her image. But it certainly exists.

I have to confess that I was thinking of the most famous example (?) which is the one on the top of the Central Criminal Court (the Old Bailey) which is not blindfold.

I apologise for not taking into account other examples.
