Mångha (måŋha) is the Avestan for "Moon, month", equivalent to Persian Māh (Old Persian māha). It is the name of the lunar deity in Zoroastrianism. The Iranian word is feminine, and consequently the personification of the Moon is a goddess, as in Greco-Roman tradition but in marked contrast both to Vedic religion and to her Mesopotamian predecessor Sin. Although Mah is not a prominent deity in the Avestan scripture, her crescent was an important symbol of royalty throughout the Parthian and Sassanid periods.
Although there are two Avestan hymns dedicated to the Moon, she is not a prominent divinity. In both the third Nyaish as well as in the seventh Yasht, the 'moon' more commonly spoken of is the physical moon. In these hymns, the phases of the moon are described at length. Ahura Mazda is described to be the cause of the moon's waxing and waning, and the Amesha Spentas evenly distribute the light of the moon over the earth (Yasht 7.3, Nyaish 3.5). In Yasht 13.14-16, the Fravashis are said to be responsible for keeping the moon and stars on its appointed course. The sun, moon, and stars revolve around the peak of Hara Berezaiti (Yasht 12.25).
The Moon is however also "bestower, radiant, glorious, possessed of water, possessed of warmth, possessed of knowledge, wealth, riches, discernment, weal, verdure, good, and the healing one" (Dhalla, 1938:214; Yasht 7.5, Nyaish 3.7). "During the spring, the Moon causes plants to grow up out of the earth" (Yasht 7.4, Nyaish 3.6). In the litany to the Moon, she is described as the "queen of the night."
The Moon is repeatedly spoken of as possessing the cithra[n 1] of the primeval bull. This is an allusion to a cosmological drama that is however only properly attested in the texts of Zoroastrian tradition (see below).
In the Zoroastrian calendar, the twelfth day of the month is dedicated to and is under the protection of the Moon.
The Moon plays a prominent role in Zoroastrian cosmogony, in particular as described in detail in the Bundahishn, a text finished in the 12th century. The legend (Bundahishn 7) runs as follows: Ahriman (Av: Angra Mainyu) incites Jeh (Jahi) the primeval whore to kill the primordial bovine Gawiewdad (Av. Gavaevodata). Jeh does as told, but as the creature lies dying, the chihr[n 1] is rescued and placed in the care of the moon. This chihr is then the "prototype" (karb) of all creatures of the animal world.
In the hierarchy of yazatas, the Moon is the assistant (or 'cooperator', hamkar) of Vohu Manah (MP: Bahman), the Amesha Spenta of animal welfare, in particular of cattle. The identification with Vohu Manah - the hypostasis of "Good Purpose" or "Good Mind" - is reflected in other texts where the moon is associated with mental harmony and inner peace.
- The precise meaning of this word in this context is unknown. It is traditionally translated as "seed", which in the sense of "prototype" carries the connotation of a particular physical form or appearance. But the word can also mean "seed" in the sense of "race, stock".
