Nomkhubulwane, also known as Inkosazana-Yezulu — "Princess of the Sky" — is a major goddess of the Zulu people: divine patroness of rain, the rainbow, agriculture, and fertility. She is among the most cherished figures in Zulu oral tradition, a being whose presence was felt in the fall of rain on parched fields, in the arc of color that follows a storm, and in the ripening of sorghum and maize in the family garden.
Daughter of the Sky
In the genealogies recorded by early ethnographers of Zulu oral history — among them James Stuart and A. T. Bryant, who gathered testimony from Zulu elders in the early twentieth century — Nomkhubulwane is described as daughter of Umvelinqangi, the primordial sky-being of Zulu cosmology. The tradition is not entirely settled on this point: some tellings place her instead within the lineage of the sky-god Nkulunkulu/uMvelinqangi, treating the two names as alternate or overlapping designations for the same high sky figure rather than as clearly separate beings. What is consistent across these accounts is that Nomkhubulwane and her fellow sky and nature deities occupy a tier beneath this supreme, ancestral sky figure, closer to the concerns of ordinary Zulu life: the weather overhead, the soil underfoot, the fertility of women and of the fields they tended.
The Rainbow as Her Signature
Among the Zulu, the rainbow that appears after rainfall is known as uthingo lwenkosazana — "the princess's rainbow" — understood as Nomkhubulwane's visible manifestation in the sky after rain. This association bound her to the rains that Zulu farmers depended upon, so that her rainbow was read not merely as a natural afterthought to a storm but as the visible sign of her passing and her agricultural blessing.
Teacher of Beer and Grain
Ethnographic accounts recorded by James Stuart and A. T. Bryant in their early-twentieth-century collections of Zulu oral history credit Nomkhubulwane with teaching Zulu women the arts of cultivation and of beer-brewing — particularly the growing of sorghum and maize, the staple grains upon which homestead life depended. This teaching role placed women at the center of her cult, since it was women who carried forward the knowledge she had given: how to prepare the soil, when to plant, how to ferment the grain into utshwala, the traditional beer that accompanied both daily sustenance and ceremonial life. In crediting a goddess with these foundational skills, Zulu tradition wove agriculture and womanhood together as a shared inheritance, passed from the divine princess down through generations of mothers and daughters.
The Festival of the Maidens
Nomkhubulwane's worship centered on rites performed specifically by young, unmarried Zulu girls. In ceremonies connected to the Umkhosi Wokweshwama — the first-fruits festival — and to reed-dance-adjacent rites in her honor, girls performed dances and rituals intended to secure the fertility of both the crops and of women themselves. These ceremonies emphasized themes of virginity and purity, reflecting a broader pattern in Zulu religious thought in which female fertility and agricultural fertility were treated as two expressions of the same underlying force — one that Nomkhubulwane governed above all.
Kinship with Mbaba Mwana Waresa
Nomkhubulwane is frequently discussed alongside Mbaba Mwana Waresa, another Zulu goddess of rain, agriculture, harvest, and beer; the two are sometimes conflated or paired as close counterparts in comparative mythology sources. Mbaba Mwana Waresa is described as dwelling in a palace amid the clouds, itself encircled by a rainbow — an image close enough to Nomkhubulwane's own rainbow association that the two figures can appear, in places, to blend into one composite vision of a sky-goddess governing both water and grain. Compilers of comparative African mythology, such as Harold Scheub, have grouped both goddesses together as sky and rain deities whose worship was carried out chiefly by women and girls in service of agricultural fertility.
The Goddess Who Married a Mortal
Among the myths gathered around Mbaba Mwana Waresa, as recorded by twentieth-century folklorists compiling African mythology sourcebooks, is the story of her love for a mortal man named Thandiwe. Unable to find a suitable husband among the gods, she is said to have disguised herself and descended from her palace in the clouds to marry him — a union credited in the popularized telling with sanctioning the human customs of marriage and lobola, the bridewealth exchanged between families. Mbaba Mwana Waresa is likewise credited in oral tradition with inventing the brewing of beer and teaching it to the Zulu people, making her a patroness of both field and hearth. Some secondary sources translate her name as relating to a "mother/goddess of the rainbow's harvest," though the scholarly grounding for this etymology outside popular mythology compendiums is thin.
Violent Cousins in the Storm
Not every being tied to Zulu weather carries Nomkhubulwane's gentleness. The Impundulu, or "lightning bird," is a shapeshifting familiar spirit in Zulu, Xhosa, and broader Southern African Nguni folklore, described as a large black-and-white bird resembling a stork or crane, said to summon thunder and lightning by flapping its wings. It is bound up closely with Zulu and Xhosa witchcraft belief — ubuthakathi — said to be inherited by witches, often passed down matrilineally, and to drink the blood of its victims, sometimes causing illness or death that traditional healers diagnose as an Impundulu attack. It is also said to be capable of transforming into a handsome young man in order to seduce and recruit women into witchcraft, and its feathers and other body parts are reputedly sought after by traditional healers, used in muthi both for protection and for malevolent ends. Colonial-era and post-apartheid ethnographic and legal-anthropological research — including studies of witchcraft accusations in South Africa's Eastern Cape — documents these beliefs still influencing witchcraft-related disputes and court cases into the twentieth and twenty-first centuries.
The Serpent of Howick Falls
Where the Impundulu governs lightning, the Inkanyamba governs the tornado. This giant eel-like or serpentine creature, sometimes described with a horse-like head, is strongly associated with Howick Falls on the uMngeni River in KwaZulu-Natal, where local tradition holds it lives in the pool beneath the falls. Its movement or anger, particularly when it migrates between water sources, is believed to cause the tornadoes that periodically strike the KwaZulu-Natal Midlands around Howick. Sangomas in the area have historically performed ceremonies at the falls to appease the creature, especially after storm damage, a practice documented by South African tourism and cultural heritage sources describing the falls as a spiritually significant site. The Inkanyamba is counted among several river-spirit or serpent deities recognized across Nguni-speaking cultures, comparable to other Southern African water-serpent beings.
Weather as Will, Not Accident
Taken together, Nomkhubulwane's rains and rainbow, the Impundulu's lightning, and the Inkanyamba's tornadoes illustrate a recurring pattern in Zulu cosmology: violent or life-giving weather is attributed to animal-spirit or divine agency rather than to impersonal natural forces. The Impundulu and Inkanyamba are both classified within the broader Zulu category of amandiki/idlozi-adjacent spirit beings — figures connected to ancestral and witchcraft cosmology, distinct from the high sky-god Nkulunkulu/uMvelinqangi. Nomkhubulwane and Mbaba Mwana Waresa, by contrast, are positioned as nature and sky deities beneath the same creator figure, their worship centered on the agricultural fertility rites of women and girls rather than on witchcraft belief.
Beneath the Great-Great One
The Zulu supreme or creator deity is generally named Unkulunkulu (uNkulunkulu, "the Great-Great One"), who in most origin narratives created the first humans from a reed bed, uthlanga. Nomkhubulwane, Mbaba Mwana Waresa, the Impundulu, and the Inkanyamba are all positioned in the pantheon beneath this creator figure, though occupying different tiers within it: Nomkhubulwane and Mbaba Mwana Waresa as beneficent nature and sky deities tied to fertility and sustenance, and the Impundulu and Inkanyamba as amandiki/idlozi-adjacent spirit beings tied to ancestral and witchcraft cosmology. This layered structure reflects a cosmology in which the sky and its moods are read as the actions of distinct beings, some benevolent and some dangerous.
Nomkhubulwane's reed-dance and first-fruit ceremonies, and the ongoing attention paid to the arrival of the rains that determine whether sorghum and maize will thrive, continue to be documented as part of living Zulu ritual practice, alongside the continuing role of sangomas in diagnosing Impundulu-related affliction and in appeasing the Inkanyamba at Howick Falls after storms.
