The symbols of justice are used for historical and ethical preservation. Throughout the evolution of society, many references have been used to honor one of the oldest professions that seeks to organize and balance disorder in the world. Here are some of the most important symbols:
BALANCE
Justice related to human behavior, laws, and balance. It seeks proportionality between punishment and guilt. In Greek culture, Zeus used the scales to decide the future of mankind. In ancient Egypt, the hearts of the dead were weighed to decide their fate after death.
HAMMER
The hammer (or mallet) used by the judge, which is made entirely of wood, symbolizes alertness, silence, and respect. There are some theories about its origin, and one of them says that the piece comes from the Norse culture through the god Thor, who had a powerful hammer called Mjollnir.
SPADE
It represents an instrument that keeps the peace, upholds laws, and punishes injustices. It symbolizes power to destroy injustice and ignorance. Associated with Themis, the Greek goddess of justice, it aims to protect the good and punish evil.
SALE
It symbolizes impartiality, which makes no distinction between those who are judged. The goddess of justice, usually represented blindfolded, does not make decisions through personal judgments. It is said that blindness was something that allowed only the gods to know secrets of humanity.
THEMIS
Within Greek mythology, the goddess Themis is the daughter of Uranus and Gaia, symbolizing the personification of justice. She is usually depicted blindfolded and holding a sword in her right hand and a scale in her left hand. Her image unites many of the symbols of justice, showing fairness, thoughtfulness, and balance.
