The Romans did not have a single god of justice; instead, they personified justice and law through several deities and divine personifications, chiefly Iustitia (Justice), along with Aequitas (Equity/Fairness), and Fides (Good Faith/Trust), each overseeing a different aspect of legal and moral order.
Who Was Iustitia?
Iustitia was the Roman goddess of justice, a personification of the concept of iustitia (justice, righteousness). She was the Roman equivalent of the Greek goddess Dike (Justice) and Themis (Divine Law). Iustitia was typically depicted as a matronly figure holding a set of scales in one hand and a cornucopia or a sword in the other. The scales represented the weighing of evidence and fair judgment, while the sword symbolized the power of the law to enforce decisions. The cornucopia, when present, signified the abundance and prosperity that justice brings to a society.
Unlike the Greek Dike, who was a more mythological figure with a clear genealogy, Iustitia was primarily a personified abstraction—a virtue made divine. She was not the subject of elaborate myths, but rather a civic and moral ideal that Romans invoked in legal and political contexts. Her cult was closely tied to the emperor, who was seen as the ultimate guarantor of justice. The emperor Augustus, for instance, built a temple to Iustitia Augusta, linking the goddess to the imperial household and presenting himself as the restorer of justice after the chaos of the civil wars.
Other Roman Deities of Law and Order
While Iustitia was the most direct personification of justice, several other Roman deities and personifications were associated with legal and moral order:
- Aequitas – The personification of equity, fairness, and even-handedness. She was often shown holding scales and a cornucopia, and her role was to ensure that laws were applied impartially. Aequitas was particularly important in commercial and property disputes, where fairness in exchange and contracts was paramount.
- Fides – The goddess of good faith, trust, and honesty. Fides was crucial to Roman law because contracts and legal agreements depended on the mutual trust of the parties. Her temple on the Capitoline Hill was a place where treaties and oaths were sworn. She was often depicted with a handshake or holding a basket of fruit, symbolizing the trust that underpins social and legal relations.
- Jupiter Optimus Maximus – While primarily the king of the gods, Jupiter was also the ultimate protector of oaths and treaties. He was invoked in legal contexts, especially in the swearing of oaths, and his role as the guardian of justice was central to Roman state religion.
- Minerva – Though primarily a goddess of wisdom and war, Minerva was also associated with justice, particularly in the sense of wise judgment and strategic thinking. She was sometimes depicted with a scale or a spear, and her wisdom was seen as essential for fair rulings.
- Justitia – A later Latin form of Iustitia, sometimes used interchangeably. In Roman art, the two names refer to the same goddess.
The Role of Personifications in Roman Religion
Roman religion was unique in its extensive use of personifications—abstract concepts that were deified and worshipped. Unlike the anthropomorphic gods of Greek myth, these personifications were often more abstract and less narrative-driven. They represented virtues, states, and social values that were essential to Roman identity. Iustitia, Aequitas, and Fides were among the most important of these because they upheld the legal and moral fabric of the state.
These personifications were not merely poetic metaphors; they had actual cults, temples, and festivals. For example, the Fides Publica (Public Faith) had a temple on the Capitoline Hill, and the Feriae Latinae (Latin Festival) included rites to Fides. Similarly, Iustitia was honored on January 8, a day dedicated to her in the Roman calendar, and her cult was promoted by emperors to emphasize their own commitment to justice.
Iustitia vs. Themis and Dike
Greek mythology had two distinct goddesses associated with justice: Themis and Dike. Themis was the personification of divine law, custom, and order, often depicted with scales and a sword. She was a Titaness, the daughter of Uranus and Gaia, and the mother of the Horae (Seasons) and the Fates. Dike, one of the Horae, was the goddess of human justice and moral order, and she was often shown holding a scale. In Roman culture, these two Greek figures were often conflated with Iustitia, but the Romans preferred their own personification, which was more closely tied to civic law and the state.
The Roman Iustitia differed from the Greek Dike in that she was more closely associated with the legal system and the emperor. While Dike was a moral force that punished wrongdoing, Iustitia was also a symbol of the emperor’s role as the supreme judge. This political dimension was absent in the Greek concept, where justice was more of a cosmic or moral principle.
How the Romans Invoked Justice in Practice
In Roman courts, the goddess Iustitia was not directly worshipped during trials, but her principles were invoked through oaths and the presence of her symbols. Judges were expected to act with iustitia, meaning they should be impartial and fair. The concept of aequitas was also crucial, as it allowed judges to interpret the law in a way that was fair rather than strictly literal. This flexibility was a hallmark of Roman jurisprudence and is still reflected in modern legal systems that distinguish between strict law and equity.
The Roman legal system itself was highly developed, with a complex body of civil law (ius civile) and a system of praetors who administered justice. The praetor’s edict, an annual proclamation of legal principles, was a key mechanism for ensuring fairness. The goddess Iustitia was a symbolic reminder of these ideals, and her image on coins and public buildings reinforced the idea that the law was divinely sanctioned.
