The Impundulu: The Lightning Bird of Southern Africa

In the storm-country of southern Africa—the Eastern Cape of the Xhosa, the Zulu lands, the highveld where the summer thunderheads build like white mountains and the lightning kills more people than almost anywhere on earth—the bolt from the cloud is not a discharge. It is a bird. The impundulu—the lightning bird of Xhosa, Zulu, and Pondo tradition; inyoni yezulu, "the bird of heaven"—is a great bird, white or black-and-white in most tellings, the size of a man when it chooses; and the thunderstorm is its visitation: the lightning is the flash of its descent—the beat of its wings is the thunder, the bolt its talons striking—and where lightning strikes the earth, there, say the traditions, the bird has landed and laid its egg in the ground. The scorched pit at the strike-point conceals it; and the egg of the lightning bird is an object of terrible ambivalence: a thing of power for the healer who knows how to take it—the strike-site's soil and the egg figure in the old storm-doctoring, by which the inyanga yezulu, the heaven-herd, treated ground and homestead against future strikes—and a seed of catastrophe if left, for the buried egg draws the lightning back: the place that was struck will be struck again, say the traditions, until the egg is found and destroyed. The heaven-herds' whole profession stood on the doctrine: lightning is not random; it nests; and the treated homestead—pegged, medicated, its old strike-eggs dug and burned—stands under the storm like a village whose visiting monster has been correctly, professionally, seen off.

The Vampire in the Storm

But the impundulu leads a double life, and its second is darker than its first. Off the storm-front, in the witchcraft traditions of the Cape, the lightning bird is the witch's supreme familiar: passed down, say the Xhosa accounts, from mother to daughter in the witch-lines, the impundulu serves its mistress as the ultimate instrument of harm—and it feeds, in this service, on blood. The familiar-bird sucks its victims—the wasting illnesses, the coughing of blood, the long consumptions of the kraals were its signature diet—and it must be fed by its keeper, on her own blood or on victims supplied, or it turns on her line; inherited unfed, it becomes the terrible ishologu, the masterless familiar, ravaging at will. In the beliefs collected across the region, the impundulu in this aspect takes the form of a beautiful young man to seduce the women it will feed on—the lightning bird as incubus, the storm's glamour turned personal—and the diviners' diagnostics for its victims (the wasting, the dreams of a lover, the chest-pressure at night) run the whole familiar-vampire register. Between the sky-bird whose egg the storm-doctors hunt and the blood-bird the witches bequeath, the tradition strung its unifying insight: the same power that splits the sky splits the household—the celestial voltage, domesticated by the wrong hands, becomes a heritable appetite; and the hamerkop—the strange, crested, omen-heavy brown bird of the waterholes, protected by taboo across the whole region, burner of the houses of those who harm it—stands in the traditions as the lightning bird's earthly cousin or double: the bird one can see, marking the presence of the bird one cannot.

The heaven-herds themselves—the izinyanga zezulu, the lightning-doctors—were a profession of standing and courage, and their practice fills out the bird's portrait. Theirs was the dangerous obligation of the storm: while the homestead sheltered, the heaven-herd went out to work the weather—whistling and calling to the storm as a herdsman to cattle (the title is exact: they herded the sky), planting the medicated pegs at the homestead's corners, burning the protective fires whose smoke the bird dislikes, and addressing the thunderhead itself in the imperative mood their initiation licensed. A homestead struck was their emergency case: the strike-site fenced at once, the household treated for the contamination the bolt brings, the ground doctored and the buried egg sought—and the herd's fees and prestige rose with every season the treated kraals stood unstruck. Their initiation, fittingly, ran through the storm itself: the future lightning-doctor was often marked by surviving a strike, or by the storm-dreams that constituted the call; and the profession's whole theology held that lightning strikes neither randomly nor innocently—somewhere behind the repeated strike stood either the bird's own nesting or a witch who had sent it, and the herd's diagnosis, like the sangoma's, ended in an address. Between the meteorology the modern highveld trusts and the heaven-herds' account stands less distance than either party admits: both hold that strikes cluster, that grounds can be treated, that protection is a profession; they differ chiefly on whether the recurrence buried at the strike-point is charge or egg—and on who should be paid for digging it out.

The Esoteric Reading: The Egg at the Strike-Point

The impundulu's theology, read esoterically, is a complete doctrine of catastrophe and its residues, and the egg is its master-clause. Lightning nests: the great sudden strikes of existence—the disaster, the ruinous passion, the bolt that burns a life's roof—are, in the tradition's physics, not events but visitations: something descends, discharges, and deposits; and what it deposits, buried at the strike-point, is an egg—a live, patient, charged residue that draws the next strike to the same ground. Every healer of persons and households knows the pattern the heaven-herds codified: the struck place is struck again; the site of the old catastrophe attracts its successors—the family that lightning of one kind or another hits, hits, and hits again is not unlucky; it is nested—and the cure is the storm-doctor's, exactly: go to the old strike-point, dig—professionally, with medicines, with help—find the egg the disaster laid, and destroy it. Grief unexcavated, trauma left buried at its point of impact, is not inert; it is ovate: it incubates recurrence. The familiar is inherited down the mother-line: the second clause is the hard one—the domesticated lightning, the appetite-bird of the witch-traditions, passes by inheritance, feeding on the line that keeps it; and the tradition's portrait of the heir's dilemma (feed it, be fed on, or loose it masterless) is the exact anatomy of every inherited family darkness: the rage, the addiction, the pattern handed down—which must be consciously received and consciously ended, for merely neglecting it, say the Xhosa accounts with terrible precision, produces the ishologu: the ancestral appetite unbound, raging without even the discipline of a keeper. And the power seduces before it feeds: the bolt comes as the beautiful young man; the voltage of the heights, turned predatory, presents as glamour—and its victims waste in dreams of love. The bird of heaven, like the great raptors of the world's high mythologies, is magnificent in its own sky; it is only in the wrong hands, and the wrong beds, that heaven's bird becomes the household's leech.

The lightning still kills terribly on the highveld and in the Cape's summer storms, and the two professions still meet at the strike-sites: the lightning-conductor installers, and—called by families the insurers never hear about—the heirs of the heaven-herds, treating the ground. The hamerkop still builds its colossal nests unmolested, protected by a taboo the bird-books duly record; the impundulu retains counsel in the region's witchcraft trials, cinema, and grandmothers. The doctrine travels wherever lightning does, which is everywhere: after every great strike in a life, when the smoke has cleared and the roof is mended—dig at the strike-point; the visitation laid something there, and what is not dug up will call the sky down again on the same ground. Do not keep the beautiful voltage as a pet, whatever it promises at the window. And whatever your mother's mothers kept feeding in the dark of the line—receive it awake, name it, and end its feeding schedule with your own generation; for heaven's bird belongs in heaven, and every tradition of the storm agrees on the one impossible, necessary task of the living: to admire the lightning, treat the ground, and bequeath, down the mother-line, nothing that eats.
