The Vegetable Lamb of Tartary: The Medieval Plant That Grew Sheep

Somewhere in the steppes beyond the Volga—in "Tartary," that vast elastic country where medieval Europe stored everything it could not verify—there grew, on the best authority, a plant whose fruit was a living lamb. The Vegetable Lamb of Tartary—the Borametz or barometz, from the Tatar word for lamb—sprouted from a seed like a melon's; its stalk rose waist-high; and at the top, attached by its navel to the stem as fruit to the vine, grew a perfect lamb: flesh, blood, bone, and a fleece of extraordinary whiteness. The lamb-plant lived bent to its tether: it grazed the grass within the circle of its stalk, cropping everything its stem allowed it to reach; and when the circle was bare—the stalk's radius exhausted—plant and lamb together died. Wolves loved its flesh, which tasted (travelers agreed, at various removes from anyone who had tasted it) like crab or like lamb itself; its blood ran sweet like honey; men prized the fleece and the bones for divination and for caps. Sir John Mandeville, that great honest liar of the fourteenth century, reported eating of it and pronounced it marvelous; Friar Odoric had heard of it from reliable persons; the baron Sigismund von Herberstein, a sober imperial ambassador to Muscovy, collected sworn testimony about it in the sixteenth century, down to its habitat between the Volga and the Don. For four hundred years the lamb grew, grazed, and died on its stalk in the margins of Europe's books—until the naturalists went looking for it, and found, at the end of the long hunt, something better than a monster: a mirror.

The Hunt for the Lamb

The Vegetable Lamb's biography is the biography of European knowledge itself. Its seed was probably double. From antiquity came rumors of the wool-bearing trees of India—Herodotus reports them plainly: trees whose fruit is a fleece surpassing the sheep's, from which the Indians made their clothes—which is to say, cotton, faithfully described and promptly mythologized: word of a plant that yields wool, passed westward through bazaars and languages until the wool grew a body, the body a life, the life a navel-cord to its stalk. And from the rabbinic literature came the Yadu'a, the plant-animal of the Talmudic commentators—a beast tethered to the earth by a stem from its navel, grazing its circle, killable only by severing the cord—already complete with the lamb's whole anatomy by the early Middle Ages. The two streams met in the bestiaries and the travel books, and the lamb became a fixture of the East: mapmakers planted it in Tartary; encyclopedists engraved it—stalk, tether, and cropped circle, exactly as the frontispiece of Henry Lee's affectionate 1887 monograph shows it; theologians pondered whether it was meat or vegetable for fasting purposes (fish-like taste argued leniency); and cabinets of curiosities exhibited, at good prices, actual specimens: little woolly lambs with legs and golden fleece, which were in fact—the exposure came in stages—the rhizomes of a Chinese tree-fern, trimmed and inverted so that the root became a body and four leaf-stalks became legs, their natural coat of golden-brown hairs supplying the fleece. The fern (it bears the name Cibotium barometz to this day, science's graceful tip of the hat to the legend it demolished) had been manufactured into lambs for the curiosity trade; Hans Sloane examined one for the Royal Society in 1698 and pronounced it a fern-root doctored by human hands; and the learned world, over the eighteenth century, closed the file: the Vegetable Lamb was cotton at one end, a barbered fern at the other, and four centuries of wonder in between.

The lamb's paper trail is a pleasure in itself. Mandeville's fourteenth-century account set the type—he ate of the fruit-beast, he says, and found it "a great marvel"—and paired it, with a traveler's even-handedness, against the barnacle geese of his own country, birds that grew on trees: each hemisphere, he implies, keeps its own plant-animals, and neither should scoff at the other. Herberstein's sixteenth-century testimony, gathered from Russian informants with ambassadorial care, gave the lamb its most respectable hour: coordinates, habitat, the sweet blood, the wolves' appetite. The seventeenth century argued it in earnest—Sir Thomas Browne doubted it in the Pseudodoxia, others defended; Claude Duret gave it chapters; the cabinets exhibited their golden fern-lambs—and the eighteenth dissected it: Sloane's fern-root verdict, then the botanists' identification of the cotton rumor beneath, until by 1800 the lamb survived only in Erasmus Darwin's verses and the antiquarians' affection. Henry Lee's 1887 monograph—written, delightfully, by the naturalist of the Brighton Aquarium—gave it the loving funeral it deserved, tracing every source; and the frontispiece of that book is the image above: the lamb on its stalk, grazing its circle, engraved at the very moment it passed from natural history into emblem, which is to say, into its immortality.

The Esoteric Reading: The Creature That Grazes Its Circle

And yet the file, closed by botany, opens again at once for the esoteric reader—because the legend, whatever its sources, is a perfect emblem, and the medieval imagination, which built emblems the way Rome built roads, knew precisely what it had. Consider the creature the books actually describe. A living softness—flesh, blood, warmth, a fleece of great value—rooted by the navel: nourished through the very cord that confines it; free to move, to graze, to live, exactly within the radius of its stem; and doomed, not by wolves, but by the exhaustion of its own circle: when the reachable grass is gone, the lamb starves at the end of its tether, and the plant that fed it dies with it. No moralist ever drew a truer portrait of the tethered life. Every soul begins as a vegetable lamb: nourished through the navel-cord of its origins—family, place, tradition, the stalk it sprouted from—and grazing, contentedly and then desperately, the circle that cord allows. The legend's cold botany is the whole diagnosis: the circle is finite; the grass within reach of any tether runs out; and the creature that cannot be severed from its stalk dies precisely of its own radius—warm, woolly, beloved, and starved at the stem. The Talmudic stratum of the legend carried the operative clause: the Yadu'a could be killed—or, read the other way, freed into death and use—only by cutting the cord; arrows were shot at the stem from outside the circle, for within the circle the creature was dangerous. Severance, says the old emblem, is performed from beyond the radius, at the tether, and it is the only harvest there is: the fleece, the sweet blood, the oracular bones—everything of value in the lamb—becomes available exactly at the cutting. The mystics did not need the fern exposed to read the lesson: what is fed by the navel must at last be cut from it, or die of a bare circle; and the cutting, which looks like killing from inside the radius, is called, from outside it, birth.

There is a second emblem folded in the first, and the age of trade read it fluently: the lamb was cotton—the plant-wool that would clothe the world—and the legend is also, therefore, the West's dream-image of the goods of the East before understanding arrived: real wealth (the fleece was always real), wrapped in a marvelous wrong explanation, exhibited as monster until examined as merchandise. Every era keeps a Tartary: the province of the true-but-garbled, where actual cotton grows actual wool and the reports come back as lambs on stalks; and the legend's history—wonder, testimony, forgery, examination, exposure, and the naming of a real fern after a false lamb—is the full life-cycle of human knowledge about anything distant, as the medieval mind's whole marvelous East testified in the letters of its greatest phantom: the wonders were never lies exactly; they were truths that had traveled too far without their explanations.

The doctored fern-lambs sleep in their museum cases—the Garden Museum in London keeps a famous specimen, woolly-golden and four-legged as ever—and Cibotium barometz grows placidly in the botanical houses, its golden-haired rhizomes unbothered by their career in monstrosity; the cotton that started it all clothes the planet. The emblem, meanwhile, has lost nothing: the circle of cropped grass around a tethered softness is drawn afresh around every life that cannot cut its cord. The legend's counsel, assembled from all its strata, is as practical as the old engravings are charming: treasure the stalk that fed you, for the fleece is real and the cord was life itself, once; watch the radius—when the grass within reach of your tether thins, the emblem has begun to speak to you personally; and when the time comes, let the cord be cut, from outside the circle if it must be, without mistaking the severance for death. It is the harvest, and it was always going to be the harvest. Everything valuable in the lamb—fleece, sweet blood, and oracular bone—comes away, the old books agree, only at the cutting—and nothing survives, on any stalk in Tartary or elsewhere, the exhaustion of its own small circle of grass.
