Mithra is an ancient Iranian deity, or yazata, who represents many vital social concepts. He is primarily known as a divinity of covenants, oaths, and contracts. This means he oversees the promises people make to one another. Mithra also governs light, justice, and friendship. He serves as a protector of Truth, known in Persian as Asha. Because he watches over the moral order, he is also a judicial figure.

His name has deep roots in language. It comes from the Proto-Indo-Iranian word *mitrám. This root means "to bind." Therefore, the name Mithra literally means "that which causes binding." This reflects his role in holding society together through sacred agreements.

In the Zoroastrian tradition, Mithra holds a very high rank. He is part of an exalted triad alongside Ahura Mazda and Apam Napat. Together, these figures help maintain social order and Khvarenah, which is the concept of legitimate rule. Mithra has many specific roles that protect the physical world. He is called "Mithra of Wide Pastures." As a guardian of cattle, he ensures the animals are safe. He also protects the waters to make sure pastures remain green and fertile.

Mithra is described with incredible, superhuman qualities in the Avesta scriptures. One text calls him "Mithra of the Thousand Ears, and of the Myriad Eyes." Another describes him as having ten thousand eyes and wide knowledge. These descriptions show that he is eternally watchful and never rests. He is an all-seeing protector who observes everything between heaven and earth. He is also described as the "Yazad of the Spoken Name." This suggests he is deeply connected to the truth of what people say.

In the afterlife, Mithra plays a crucial role in the judgment of souls. He is one of three judges at the Chinvat Bridge. This is the "Bridge of Judgment" that all souls must cross. He works alongside Rashnu, who represents Justice, and Sraosha, who represents Obedience. While Sraosha acts as a psychopomp, or a guide for souls, Mithra is a judge. If a person's Good Thoughts, Words, and Deeds outweigh their Bad, the soul is conveyed across the bridge. Mithra remains a benefactor to humankind, provided they love the truth.

The history of Mithra shows how his importance changed over centuries. In the Achaemenid period, several kings invoked his name. Artaxerxes II was notable because he asked Mithra to protect him. This was a change from earlier kings who only named Ahura Mazda. Artaxerxes II even set up statues of his patron divinities. Later, the Persian leader Darius III also invoked the sun and Mithra before the Battle of Gaugamela.

These accounts show that leaders looked to Mithra for protection and legitimacy.

There are also complex connections between Mithra and the sun. In some Zoroastrian traditions, Mithra evolved to be identified with the sun itself. This may have happened because of contact with other cultures. Some scholars suggest this was due to connections with the Babylonian god Shamash or the Greek god Apollo. However, other texts like the Khorda Avesta treat the sun, Hvare-khshaeta, as a separate entity. In these texts, the sun and the moon are described as having a "Best Friendship." This shows that the relationship between Mithra and solar light is a deep and varied subject.

Even today, the legacy of Mithra remains visible in various systems. The Iranian civil calendar still uses the name "Mihr" for the seventh month. The sixteenth day of the month is also dedicated to his protection. This placement reflects his high rank in the hierarchy of divinities. People celebrate a festival called Mehregan to honor him. Beyond religion, his name has even reached outer space. A near-Earth asteroid is named Mithra. This links an ancient concept of binding and truth to the modern study of the cosmos.
