What was the ancient Roman goddess of justice wearing as a symbol of her impartiality?

Lady Justice is an allegorical personification of the moral force in judicial systems. Her attributes are a blindfold, a beam balance, and a sword. She often appears as a pair with Prudentia, who holds a mirror and a snake.

Lady Justice originates from the personification of Justice in Ancient Roman art known as Iustitia or Justitia after Latin: Iustitia, who is equivalent to the Greek goddesses Themis and Dike.

Since the 16th century, Lady Justice has often been depicted wearing a blindfold. The blindfold represents impartiality, the ideal that justice should be applied without regard to wealth, power, or other status. The earliest Roman coins depicted Justitia with the sword in one hand and the scale in the other, but with her eyes uncovered. Justitia was only commonly represented as "blind" since the middle of the 16th century. The first known representation of blind Justice is Hans Gieng's 1543 statue on the Gerechtigkeitsbrunnen (Fountain of Justice) in Berne.
