Mehregan is an ancient Iranian festival honouring Mithra, the deity of light, friendship, love and the autumn harvest.
Rooted in Zoroastrianism, the festival falls on the 16th day of the month of Mehr (2nd October) and marks the beginning of the harvest season. Once called Mithrakana, meaning “belonging to Mithra” in Avestan, it is believed that it was originally aligned more closely with the equinox.
Commemorated since the Achaemenid period (550-330 BC), it was a celebration of great importance and grandeur and this is reflected in its repeated attestation in classical sources.
The Greek geographer Strabo (64 BC-24 AD) reports that the Armenian governor sent the King 20,000 horses at the Mithrakana festival, and documents the Persians’ widespread worship of Mithra.
Ctesias of Cnidus (late 5th- early 4th century BC), a Greek physician serving at the Achaemenid court, records that the King was permitted to become intoxicated solely on the day when sacrifices were offered to Mithra. Duris of Samos (c.340-260 BC) confirms this record, adding that the King performed a dance in honour of Mithra.
These are but a few of the numerous records of Mehregan and Mithra's worship in Iran. Together they suggest Mithrakana was a major Achaemenid festival, its influence later echoed in Rome as the cult of Mithras.
Today, the celebration of Mehregan was designated UNESCO protected as the Intangible Heritage of Humanity. At the heart of the festival is a table of seasonal produce - pears, grapes, pomegranates, apples, rice, wheat - decorated with dried marjoram and symbolic items such as a bowl of water, nuts, sweets, rose water and esfand (wild rue). Sormeh (traditional kohl eyeliner) is worn as a good omen, and the day is marked with music, dancing, and joy in gratitude for nature’s bounty.
