Mithra

Section 1: Overview

[BEGINNER]

Mithra (Avestan Miθra, Old Persian Mithra) is one of the most ancient divinities of the Indo-Iranian world — his name is cognate with the Vedic deity Mitra, indicating a shared pre-Zoroastrian origin dating to before 1500 BCE. In the Zoroastrian tradition, Mithra is a yazata — a being "worthy of worship" — not the supreme creator (that is Ahura Mazda), but one of the most revered divine helpers.

Mithra's primary domain is covenant, contract, and oath. His name itself means "contract" or "treaty" in proto-Indo-Iranian. He watches over agreements between humans, between kingdoms, and between humanity and the divine order. To break a covenant is to violate Mithra.

He is also associated with the light that precedes the rising sun — dawn, clarity, the first luminescence that reveals truth. In later Iranian tradition, Mithra became closely identified with the sun itself.

[INTERMEDIATE]

The Mihr Yasht (Yasht 10) of the Avesta is one of the longest and most poetic hymns in the Zoroastrian canon, dedicated entirely to Mithra. It depicts him as:

• Sleepless and ever-watchful, with a thousand ears and ten thousand eyes
• Riding a chariot drawn by four immortal white horses
• Armed with a silver-shafted golden mace, a bow, arrows, and a spear
• The protector of the righteous, the destroyer of covenant-breakers

From the late Achaemenid and Parthian periods, Mithra was widely venerated across the Iranian plateau. In the Hellenistic and Roman worlds, a distinct but related mystery cult — Mithraism (Mithras) — spread among Roman soldiers from the 1st to 4th centuries CE, centred on bull-slaying (tauroctony) iconography found across the Empire. Scholars debate how much Roman Mithras draws on Iranian Mithra versus representing a new Hellenistic synthesis.

Section 2: Worship

• Mehregan — the autumn festival of Mithra, still celebrated by Zoroastrians and in Iranian cultural tradition, held in early October (16 Mehr in the Iranian calendar)
• Mihr Yasht — recited in liturgy
• Among Parsis, Mithra is invoked in the daily Khordeh Avesta prayers

Section 3: Relationships

• Ahura Mazda — supreme god whom Mithra serves
• Vedic Mitra — cognate Indo-Iranian deity
• Sraosha, Rashnu — fellow yazatas; together with Mithra they form the judges of the soul after death
• Roman Mithras — later Hellenistic mystery cult of disputed relationship
