Jumart

Jumart is a biology topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Jumart rather than just read about it. In short: A jumart, bif, or baf is a mythical hybrid between a bull or cow and an equine (horse or donkey). Descriptions of such animals appear in numerous naturalist texts and travel accounts from the 1600s, 1700s, and 1800s.

Key takeaways

  • Jumart belongs to biology; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Jumart to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Jumart from memory before moving on to harder problems.

Reference excerpt

A jumart, bif, or baf is a mythical hybrid between a bull or cow and an equine (horse or donkey). Descriptions of such animals appear in numerous naturalist texts and travel accounts from the 1600s, 1700s, and 1800s. Such hybridization is now believed to be biologically impossible. The described specimens are now thought to have been hinnies (hybrids of a male horses and female donkeys) or equines afflicted with achondroplasia.

Etymology The first record of a jumart appears in Conrad Gesner's Historia Animalium, published from 1551 to 1587, in which it is referred to as a jumar. The term first appears in a French-Latin dictionary in 1670 as jeumarre. Numerous alternate spellings and regional variants have been recorded; these include jumarre, jumerre, gimerre, gemar, gemart, gémart, jemerri, jeumarre, jimère, jumère, joumar, and choumarrou. The terms baf (for the issue of a bull and a mare), bif (the issue of a bull and a donkey), kumrah, hinnulus, and hippotaure were also employed. The Provençal writer Frédéric Mistral proposed that the term jumart (jumarre) may derive from chimera. The writer Jacques Mulliez noted in a later essay that the term chimera was used often used to describe a hermaphroditic livestock animal, an infertile or masculine woman, or an animal with a malformed jaw. The philologist and literary critic Leo Spitzer proposes that jumart may be a regional pronunciation of the French word for mare, jument. He also suggests a relation to the word gimère, which he defines as a 14th century term for a pièce en fer du moulin (an iron piece of a windmill), possibly referring to the animal's protruding lower jaw. Other possible derivations include the Algerian word for donkey, hmara, the Hebrew word for donkey, chamor, and the French word for twin, jumeau. In Italian, the jumart is referred to as a gimerou, giumarro, or gimerro.

Description

The jumart is most often described as having the body of an equine with the head (and sometimes the tail) of a bovine. It is generally described as lacking horns but possessing small protrusions on its head in place of horns. Other accounts describe the jumart as being nearly indistinguishable from an ordinary mule. The jumart is frequently described as having an upper jaw which is shorter than the lower jaw (though one account reverses this, describing the animal as having "upper fore-teeth remarkably more forward than their under.") Some accounts reported that jumarts fathered by bulls lacked incisors in their upper jaws. Jumarts were generally described as being small in stature. The French naturalist Pierre-Joseph Buc'hoz gave the animal's height as "trois pieds, deux pouces" (literally "three feet and two thumbs"), or approximately 1.03m. The agronomist André Sarcey de Sutières, who claimed to own three of the animals, gave a similar estimate of trois pieds, trois pouces. The pastor Jean de Léger reported that jumarts produced from bulls and mares ("bafs") were, predictably, said to be larger than those produced from bulls and jennies ("bifs"). Jumarts were frequently described as displaying strength out of proportion to their stature. The French zoologist and hippiatrie (equine physician) François-Alexandre de Garsault reported that the jumart (like its non-fictional counterpart the mule) was sterile despite possessing reproductive organs.

Behavior The jumart was generally described as having an obstinate and vicious temperament. Léger reported that the creature was said to eat little and travel swiftly. By contrast, the Italian writer Giuseppe Barreti describes it as "a sluggish beast; scarcely sensible of the bit and whip; but wonderfully sure-footed." Several accounts highlight the jumart’s utility as a mount and pack animal. According to an account by the Genevan naturalist Charles Bonnet, the cry of a jumart did not resemble that of either of its parents but was similar to that of a goat.

Selected examples

English-language accounts The Scottish surgeon Patrick Blair includes an account of the jumart in his 1720 Botanic Essays in Two Parts:"And when of a Bull and a She-Ass is procreated a certain Animal, called Joumar*, as I am credibly inform'd by the Intelligent Dr. [James] Sherard, who has often seen them in Turkey, where they are very frequent, and of great Use, as being excellent Beasts of Burthen [stet] and of a quick Pace upon a March, a property not very incident either to Father or Mother."The English cleric Thomas Sedgwick recounts his ride on a supposed jumart in 1738:"Now, at first I thought it was a sturdy, wicked-looking mule; but on eyeing him again and again my belief was staggered, and I asked the Prieur's man, who followed me, what manner of brute it might be"..."On I went then, on my jumarre, examining him from head to foot, and, above all things, having an eye to his vile dispositions to break my neck down the rocks"..."Did Vincent's mule dare approach it, a bite and a kick were his sure welcome."The missionary Thomas Shaw describes an alleged donkey-cow hybrid in his 1757 work Travels, or observations relating to several parts of Barbary and the Levant:"To the Mule we may joyn [stet] the Kumrah, as, I think, these People call a little serviceable Beast of Burthen [stet] begot betwixt an Ass and a Cow. That which I saw was single hoofed like the Ass but distinguished from It in all other Respects, having a sleeker Skin and the Tail and Head (excepting the Horns) in Fashion of the Dam's."

Official records and purported specimens A review on the legendary hybrid authored by Daniel Meslé notes that jumarts appeared on a statistical inventory of livestock of the Alpes-de-Haute-Provence published in 1804 alongside mules and were recorded in numerous provinces in the southeast of France. The Musée Fragonard d'Alfort, a museum of anatomical oddities located in the École Nationale Vétérinaire has the skull of an alleged jumart in its collection (now known to be a horse with achondroplasia).

Worked examples

Example 1 — a first encounter with Jumart

Start with the simplest possible case. Write down what Jumart claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Jumart before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Jumart ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Jumart

In research
Jumart appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Jumart in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Jumart is common in secondary-school and first-year university syllabi. It links to neighbouring topics Bovid hybrids, Equine hybrids, French folklore, so understanding it makes those chapters shorter.
In everyday life
Look for Jumart outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
