Introduction
Mah is the divinity of the Moon in the Zoroastrian and Iranic tradition: the gentle lunar power in whose bright station, in the great myth of creation, the essence of the slain Primordial Ox was purified, so that from it sprang the grains, the healing plants, and the many kinds of animals that fill the living world.
In the cosmology of the tradition, when the Primordial Ox was slain in the assault of the evil spirit Ahriman, its seed or essence was carried up to the station of the Moon, and there, in the pure light of Mah, it was cleansed and made ready, so that the animal world could spring from it. For this reason Mah bears the beautiful title of the keeper of the seed of cattle, and is honoured as one of the gentle powers of the good creation.
Like the other divinities of the Zoroastrian pantheon, Mah belongs to the shared ancient religious and mythological heritage of the Iranic peoples, a tradition the Kurds hold in common with the Persians and others of the Iranic world. To know Mah is to encounter the gentle light of the Iranic religious imagination, the Moon whose pure radiance purified the seed of life and brought forth the living world.

Who Is Mah?
Mah, from the Avestan word for the Moon, is the lunar divinity of the Zoroastrian and Iranic tradition, a yazata or worshipful being who presides over the Moon and its light. Though not among the greatest of the divinities, Mah holds a beautiful and significant place in the cosmology, for it is in the bright station of the Moon that, in the great myth of creation, the essence of the slain Primordial Ox was purified, so that from it came the animals and plants of the world. For this reason Mah bears the title of the keeper of the seed of cattle. The Moon is honoured as a gentle power of the good creation, the cooperator of the holy immortal of the good mind, who is connected with the welfare of animals, and is associated with the ordering of time, the months and seasons marked by the lunar phases. Mah has his own hymn among the sacred texts and is honoured in the Zoroastrian calendar and worship. As the divinity of the Moon and the keeper of the seed of life, Mah is one of the gentle and significant powers of the Iranic religious vision.
The Moon in Name and Nature
The name Mah comes directly from the Avestan and Iranian word for the Moon, a word of great antiquity, cognate with the words for the Moon and the month across the wider Indo-European family, including the English word moon itself. The same word means both the Moon and the month, for the lunar cycle measures the months of the year.
In the tradition, Mah is the divinity presiding over the Moon, and the Moon itself is the visible body and emblem of this gentle power. The lunar divinity is masculine in the Iranic tradition, and the Moon's phases, its waxing and waning, are described and celebrated in the hymns. The Moon's light, gentle and pure, is honoured as a beneficent power of the good creation, the soft radiance that illumines the night, in contrast to the brighter blaze of the sun. The crescent of the Moon was an important and beloved symbol in the Iranic world, appearing as an emblem of royalty and divinity through the long ages of the Iranian empires. The name and nature of Mah are thus rooted in the Moon itself, the gentle light of the night sky honoured as a divine power, the lunar body and the divinity who presides over it being closely identified. As the Moon in name and nature, Mah is the gentle luminary of the night, the divine power of the lunar light, whose beautiful role in the myth of creation gives the Moon its special place in the Zoroastrian vision.

The Keeper of the Seed of the Ox
The most beautiful and significant role of Mah in the Zoroastrian cosmology is as the keeper and purifier of the seed or essence of the slain Primordial Ox, a role expressed in his stock title, the Moon that keeps in it the seed of cattle.
In the great myth of creation, the Primordial Ox, the uniquely-created first bovine, was slain when the evil spirit Ahriman assaulted the good creation. But as the Ox died, its seed or essence, its cithra, was rescued and carried up to the station of the Moon. There, in the pure and gentle light of Mah, the essence of the Ox was cleansed and purified, made ready to bring forth life. This role as the keeper and purifier of the seed of the Ox is the special and beautiful significance of Mah, expressed in the title by which the Moon is repeatedly honoured in the hymns and litanies: the Moon that holds the seed of cattle. The Moon is, in this sense, the cradle in which the essence of the animal world was purified and preserved after the death of the primal Ox, the gentle light in whose care the seed of life was made ready. This cosmological role binds Mah closely to the myth of the Primordial Ox and to the origin of animal life, the Moon being the place where the essence of the slain Ox was cleansed and prepared. It is as the keeper of the seed of cattle, the purifier of the essence of the primal Ox, that Mah holds his most significant and beautiful place in the Zoroastrian vision of creation.
From the Moon, the Living World
From the seed of the Primordial Ox, purified in the light of the Moon, came the living world of animals and plants, so that the Moon was the cradle from which the animal creation sprang.
In the tradition of the Bundahishn, the great compendium of Zoroastrian creation lore, after the essence of the slain Ox was purified in the station of the Moon, it brought forth the living world. From the purified seed came, in the tradition, the many pairs of animals of many species, so that all the kinds of beneficent animals descended from the essence cleansed in the Moon; and from the body and essence of the Ox came also the grains and the healing plants, the many kinds of crops and medicinal herbs that sustain and heal. Thus the Moon, in whose light the seed was purified, was the cradle of the living world, the gentle power in whose care the essence of life was made ready to bring forth the animals and plants. This role gives the Moon a beautiful place in the cosmology, as the purifier and the cradle of the seed of life, the gentle luminary through whose pure light the death of the Primordial Ox was turned into the bringing forth of the living world. From the Moon, in this sense, came the living world of animals and plants, the fruit of the purified seed of the primal Ox. It is one of the loveliest images of the Zoroastrian creation myth, the gentle light of the Moon as the cradle in which the seed of life was cleansed and prepared, so that from it the living world might spring.
Cooperator of the Good Mind
In the order of the divine beings, Mah is connected with the welfare of animals, serving as the cooperator or assistant of the holy immortal of the good mind, who presides over the animal creation, especially cattle.
Among the Amesha Spentas, the holy immortals, the one called the good mind, Vohu Manah, is connected with the welfare of animals, especially cattle, the beneficent creatures so important to human life. Mah, the Moon, in whose light the seed of the Primordial Ox was purified to bring forth the animals, is fittingly the cooperator or assistant of this holy immortal, sharing in the care and welfare of the animal creation. This connection reflects the role of the Moon in the origin of animal life and binds Mah to the protection and flourishing of the creatures that sprang from the purified seed. The gentle light of the Moon, associated with growth and with the moisture and rhythms that nourish life, is naturally connected with the welfare of the animals and the fruitfulness of the living world. As the cooperator of the good mind in the care of animals, Mah takes his place in the order of the divine beings as a gentle power of the good creation, sharing in the protection of the animal world whose origin lies in the purified seed of the Moon. This role as a helper in the welfare of animals is fitting for the Moon that keeps the seed of cattle, the gentle luminary connected with the flourishing of the living world it helped to bring forth.
The Moon in Worship and Time
Mah, the Moon, is honoured in Zoroastrian worship and is bound up with the ordering of time, for the lunar phases measure the months and mark the rhythms of the calendar and the seasons.
The Moon has its own hymn among the sacred texts, the Mah Yasht, and its own litany, the Mah Niyayesh, recited in its honour, especially at the phases of the new, full, and waning moon. In the Zoroastrian calendar, a day of the month, the twelfth, is dedicated to and under the protection of the Moon, and the faithful honour Mah in their prayers and observances. The lunar phases, the waxing and waning of the Moon, measure the months, for the very word Mah means both the Moon and the month, and the Moon is thus bound up with the ordering and reckoning of time, the rhythms of the calendar and the seasons. In the long history of the Iranic world, the crescent of the Moon was a beloved and important emblem, a symbol of royalty and of the divine through the ages of the great Iranian empires. The honouring of the Moon in worship and its connection with the ordering of time are thus significant aspects of Mah, the gentle luminary honoured in hymn and litany and bound up with the measuring of the months and seasons. As the Moon in worship and time, Mah is the gentle light honoured by the faithful and woven into the very reckoning of the calendar, the lunar power whose phases mark the rhythm of the year.
Symbolism and Meaning
Mah, the Moon, embodies above all the theme of purification and the cradling of life, for it is in the pure light of the Moon that the seed of the slain Primordial Ox was cleansed and made ready to bring forth the living world. In this, the Moon represents the gentle, purifying power through which life is prepared and renewed.
The Moon embodies, too, the gentle light of the night, the soft radiance honoured as a beneficent power of the good creation, in contrast to the brighter blaze of the sun, the quiet luminary that illumines the darkness. And in its connection with the months and seasons, the Moon embodies the ordering and rhythm of time, the lunar cycle that measures the year and marks the turning of the seasons. In all this, Mah is a gentle and significant power of the Iranic religious vision, embodying purification, the cradling and renewal of life, the gentle light of the night, and the rhythm of time. The Moon that keeps the seed of cattle, in whose pure light the essence of the primal Ox was cleansed to bring forth the living world, is one of the loveliest images of the Zoroastrian creation myth, the gentle luminary whose role in the origin of life gives it a special and beautiful place in the religious heritage that the Kurds share with the other heirs of the Iranic tradition.
Mah and the Kurds
Mah, like the other divinities of the Zoroastrian pantheon, belongs to the shared ancient religious and mythological heritage of the Iranic peoples, a tradition that the Kurds, as an Iranic people, hold in common with the Persians and others of the Iranic world. The reverence for the Moon and its gentle light is part of the deep heritage of the whole region.
For the Kurds, the ancient Iranic religious heritage, including the veneration of the heavenly bodies and the gentle powers of the good creation, is part of the deep background of their cultural and spiritual world. The reverence for the Moon, the marking of time by its phases, and the beauty of its light are part of the broad heritage shared across the Iranic world and beyond. It is honest and accurate to understand Mah as part of this shared ancient Iranic heritage, rather than as a uniquely Kurdish figure; the Moon divinity belongs to the common ancient religious tradition of the Iranic peoples, with roots reaching back to the most ancient layers of the tradition. As an Iranic people with ancient roots in this world, the Kurds share in this heritage, of which the Moon divinity Mah is a part, alongside the other heirs of the Iranic tradition. In presenting Mah, then, we present a figure of the shared ancient Iranic heritage to which the Kurds, as an Iranic people, are heirs, the gentle luminary whose beautiful role in the myth of creation is part of the religious vision that underlies the traditions of the region. The reverence for the Moon and its light is a value of wide and gentle resonance across the Iranic and wider world.
Debates and Misconceptions
Is Mah a major divinity? Mah is not among the greatest of the Zoroastrian divinities, such as the holy immortals or the great yazatas like Mithra and Anahita. The Moon is honoured but is a more modest power, with a relatively small place in the scriptures. Yet Mah holds a beautiful and significant role through its part in the myth of creation, as the keeper and purifier of the seed of the Primordial Ox, and it is honoured with its own hymn and a day in the calendar. So while Mah is a lesser divinity in prominence, its cosmological role gives it a special and memorable place in the tradition.
Is the worship of the Moon a form of nature-worship apart from the one God? In the Zoroastrian understanding, the Moon and the other heavenly bodies and natural powers are honoured as creations and beneficent powers of the one God, Ahura Mazda, parts of the good creation through which the divine order works, rather than as independent gods apart from the Wise Lord. To honour Mah is to honour a gentle power of the good creation and, through it, the Creator who made it. This preserves the fundamentally monotheistic character of the faith, in which the natural powers are reverenced as parts of the divinely-made good creation.
Is Mah a specifically Kurdish figure? No; like the other divinities of the Zoroastrian pantheon, the Moon belongs to the shared ancient Iranic religious heritage, a tradition the Kurds hold in common with the Persians and others of the Iranic world, rather than a uniquely Kurdish figure. As an Iranic people, the Kurds share in this broad and ancient heritage, of which Mah is a part, alongside their neighbours.
