A wheat may change into a zunin and a male hyena into a bat " : Transformation of Plants and Animals in the Literature of the Jewish Sages “

A prevalent Talmudic theory claims that both animals and plants can change, whether in the development process of the embryo or throughout the life of the organism. The current article analyzes the concept of the transformation. It shows that this view was rooted in Greco-Roman literature and the Jewish sages derived their outlook from the classical world with which they were familiar.

The main approach mentioned in Tannaitic and Amoraic literature is that basically a certain species, plant or animal, bears fruit or develops according to its traits.This fact was mentioned in various sources.For example, the Bavli (Nidd.31a) says of the sowing of species of vegetables: "If a man puts different seeds in a bed each grows in the manner of its own particular species, whereas the Holy One, blessed be He, fashions the embryo in the woman's bowels in such a manner that all grow into one and the same kind."Similarly, it says about crops: "Have you ever sowed and nothing grew or have you ever sowed wheat and harvested barley".1 Namely, normally the seed of a certain species of plant develops into the same species.
Nonetheless, there is a prevalent Talmudic theory whereby both animals and plants can change, whether in the development process of the embryo (i.e.pre-birth) or throughout the life of the organism.In this paper, I shall show that the concept of the transformation is rooted in Greco-Roman literature, and that the Jewish sages derived their outlook from the classical world with which they were familiar.2

Plants Transformation in Talmudic Literature
Jewish sages refer to the phenomenon of transformation of plants in both halakhic and philosophical contexts.For example, they say that during the creation of the world the earth deviated from God's orders and brought forth barren trees as well, although the original plan called only for fruit trees: And if so, why was the earth cursed?R. Yuden bar Shalom said: For disobeying the decrees of the Holy One, blessed be He.[It says] 'Let the earth bring forth grass, the herb yielding seed' and it did not do so, rather 'And the earth brought forth grass, and herb yielding seed after its kind'.Rabbi Pinchas said […] it added barren trees" (yKil.1:7, 27b).
A similar theory is put forth by Israeli Amoraim on behalf of previous sages.R. Lulini of the fourth generation and R. Azarya of the fifth generation cite a tradition that explains the complete annihilation of the generation of the flood as caused by the transformation of the natural-normal behavior of creatures, human beings, animals, and even the earth and the plants that grow in it: R. Azarya in the name of R. Yehuda: Everyone behaved abominably in the generation of the flood, the dog with the wolf, rooster with the peacock, that is what is meant by 'for all flesh had corrupted etc' (Gen.6:12), R. Lulini bar Tiberi in the name of R. Yitzhak: Even the earth fornicated.They would sow wheat and the earth would produce zunin, these are the zunin of the generation of the flood. 3searchers of the Talmudic botany identify the zunin in this passage as Lolium temulentum or Cephalaria syriaca, and it seems that the first suggestion is more reasonable (Figure 1). 4 The phenomenon of the transformation of plants was mentioned in rabbinical literature in the context of the laws of kilayim ("Mixture", prohibition of crossbreeding seeds, crossbreeding animals).The Mishna in Tractate Kilayim (1:1) states that wheat and zunin that are in the field together are not kilayim: "The wheat and the zunin are not kilayim in each other".In the midst of the discussion in the Tannaitic source, the Yerushalmi (Kil.1:1, 26d) asks: "From now they [the zunin] will be kilayim with wheat?"To this Rabbi Yona, one of the greatest Palestinian Amoraim of the fourth generation, replies: "They are a species of wheat, in which the fruit fornicate, as it is written: 'And the land shall not fornicate'.From here we know that the fruit fornicate". 3THEODOR and ALBECK, 1903, Genesis Raba, Parasha 28, 6, 7, p. 226.Compare to the midrash that likens marriage to a daughter of Aner, Eshkol, or Mamre to the danger ensuing from the transformation of wheat into zunin, i.e., there is a concern that the offspring born of this marriage would be corrupt like the transformation of wheat into zunin (Genesis Raba, ibid., 59, 3-4, p. 636). 4Lolium temulentum has a few common English names: Bearded ryegrass cockle, darnel or poison darnel.From now on, I shall use the Hebrew name zunin.I have adopted the identification of FELIX, 1967, p. 22. CHIZIK, 1952, p. 802 suggested that this is Cephalaria syriaca, and see there Felix's criticism of this suggestion.
Namely, In fact, wheat and zunin are species of wheat, such that they do not form kilayim when mixed, however in practice superior species of wheat lose their good traits and become inferior species or weeds.5Interestingly, some of the interpretations of the curse of Adam see the transformation into weeds of cultural species sown by man in his field as a punishment for Adam's sin.Aside from the bad effect of the sin on the sinner himself, wider circles are affected as well.The sin causes a distortion of nature and a deviation from the biological processes that operate within it. 6 may be noted that the theory of the transformation of plants became embedded in Jewish medieval agricultural folklore.Rabbi Nathan ben Yeḥiel me-Romi (Rome) who lived and operated in Italy in the 11 th century referred to the agricultural phenomenon of plant transformation in his interpretation of the bHor.13a: Some legumes have been transformed, like zunin in wheat.Thus, the legumes in these beans are sealed and hard and are not edible by human teeth, and birds and beasts do not eat them either because they are sealed and hard as a rock, and these are called gugmi in Aramaic. 7bbi Nathan ben Yeḥiel me-Romi refers to the transformation of legumes' qualities, such as the transformation of the broad bean (Vicia faba).Just as wheat is supposed to produce edible kernels, but sometimes they become zunin, which are bitter and ruin the dough, so sometimes the qualities of beans and other types of legumes are transformed for the worse.In these cases the legumes become hard and only mice can eat them.

Transformation of animals in Sages' Texts: The Case of the hyena
The main example of the transformation of animals in sages literature is that of the striped hyena (Hyaena hyaena syriaca), a nocturnal predator that feeds on small animals as well as carcasses and their bones (Figure 2).According to Yerushalmi hyena can change its sex: "male hyenas become female" (yShab.1:3, 8a).The Talmud Bavli (B.K. 16b) adds that a male hyena may change into other animals and therefore appears in rabbinical literature under three different names bardelas, naphraza and apa: The male hyena [zavoa] after seven years turns into a bat [ataleph], the bat after seven years turn into an 'arpad' [arpad], the 'arpad' after seven years turns into a 'kimosh, the 'kimosh' after seven years turns into a 'xoax', the 'xoax' after seven years turns into a demon [shed].The spine of a man after seven years turns into a snake [naḥash].
As noted by the Israeli zoologist Menaḥm Dor, it is difficult to identify the animals in this Talmudic source with certainty, and the source may refer to mythical animals. 8ccording to this source, the hyena ultimately turns into a devil, undoubtedly a creature arousing fear in the ancient world, which alludes to the hyena's potential to cause harm and have a devilish nature.

The origins of transformation theory: The classical literature
As we stated before, the concept whereby animals and plants are transformed into other species appears in Greco-Roman agricultural and natural literature.The abnormal sexual organs of the hyena was described a few centuries before the Yerushalmi in the classical sources.Aristotle (384-322 BC) had declared in the Historia animalium: "The statement is made that the hyena has both male and female sexual organs; but this is untrue."9Namely, many Roman Scholars hold the theory that hyena is hermaphroditic animal.
Pliny the Elder (23-79 AD) refers to the statement of Aristotle in his book Naturalis Historia.He writes: 'The hyena is popularly believed to be bi-sexual and to become male and female in alternate years.The female bearing offspring without a male; but this is denied by Aristotle."10Although Pliny expressed his disagreement with Aristotle on the belief in the hyena's ability to change its sex, he supported this belief.In another source, he presents this belief without qualification. 11gard to the transformation of plants Pliny the elder reports on changes that occur in various crops and why this is so.He writes: The first of all forms of disease in wheat is the oat .Barley also degenerates into oats, in such a way that the oat itself counts as a kind of corn, inasmuch as the races of Germany grow crops of it and live entirely on oatmeal porridge.The degeneration in question is principally due to dampness of soil and climate, but a subsidiary cause is contained in weakness of the seed if it is held back too long in the ground before it shoots out 12 .
In the agricultural folklore of the classical era, oats (Avena) were seen as a weakened form of higher quality crops, such as wheat and barley.Pliny suggests that the scientific explanation has to do with the moistness of the ground and the climate, but sometimes, albeit secondarily, also as a result of slowly sprouting seeds.
In fact, the issue of plant transformation aroused disagreement among non-Jewish sages, and some objected to this concept.In his book 'Hexaemeron', a collection of nine sermons on five of the six days of creation, written by Christian theologian Basil the Great (329-379 AD) of Caesarea in Cappadocia,13 the author presents a theological theory whereby God created all creatures in a certain format, such that no claim can be made of changing their original form.Basil the Great writes: So let the earth put forth herb, grass sowen as seed for its kind" […] So how does the earth put forth every seed for its kind?For how often do we sow grains of fine wheat, and we find that they become a different sort in black!This does not mean that they changed from their own species to become thus; but it happened to them as a form of illness and disease.For the wheat did not fail to become wheat in that colour, but from the burning that happened to it from the cold it received the mark of blackness.From the very name you can learn about its appearance.For from the severity of the ice it was burned so it took on another colour and a different taste.Those who have experience of seeds say that if there occurs for it a temperate and mild air with good earth, it returns again and is reestablished in the form in which it originally was.So without the command of God it is impossible for those things which grow from the earth to attain completion in a different form. 14sil believed that plants may change, but not to other species.Wheat kernels often change their traits, but this is the result of a disease.For example, wheat kernels become black as a result of the cold, but it is clear that weeds are not formed from wheat.Fundamentally, his approach is logical, as ground, weather, and precipitation also have an impact on plants, but not in a way that transforms them into other species.Clearly, for example, as a result of extreme heat, disease, or large quantities of rain, plants might change their regular appearance.
5 Discussion: Is there any basis to the ancient theory of transformation of wheat and hyena?
The fundamental question that arises in light of everything presented above is: Does the phenomenon of plant or animal transformation described in both Jewish and non-Jewish ancient writings, have any botanical or zoological basis, or is this a completely fictional concept?
The basis of the concept of plant transformation mentioned in the ancient sources seems to be an interpretation of the affinity and differences between two related plants located together in the same cultivated field.For example, the ancients discerned the morphological-botanical resemblance of wheat and darnel, manifested among other things in their external appearance or their parts, for example the flower which is a 14 THOMSON, 1995, Homily Five, 5, 37 [72], p. 60-61.
spike. 15On this basis they attempted to explain this phenomenon as transformation from one species to another due to different physical conditions.
The relationship between wheat and darnel, mentioned together often in Jewish sources, is a good example for explaining the logic of the ancients' theory of plant transformation, and therefore we shall focus on it.According to the modern scientific conception, the phylogenetic resemblance between the two is evidence of an ancient evolutionary connection.Furthermore, darnel is a segetal plant (arable plant), i.e. a weed whose main area of dispersal is currently cultivated fields.In general, segetal plants have several qualities that are valuable for their adaptation and that ensure their dispersal in agricultural fields. 16Darnel has similar qualities to those of wheat, which help it maintain its existence in grain fields.
In the case of the hyena, some zoologists believe that the source of this belief is the appearance of the large female clitoris, which is similar to the male sexual organ (Figure 3).The American zoologist Stephen Jay Gould explains why the legend that the hyena is hermaphroditic is false: The legend had arisen for a good reason.Female hyenas are virtually indistinguishable from males.Their clitoris is enlarged and extended to form an organ of the same size, shape, and position as the male penis.It can also be erected.Their labia have folded up and fused to form a false scrotum that is not discernibly different in external form or location from the true scrotum of males.It even contains fatty tissue forming two swellings easily mistaken for testicles.British zoologist L. Harrison Matthews wrote the most extensive anatomical description of the hyena's sexual anatomy in 1939 (Figures 4-5).He described the peniform clitoris, emphasizing that it is no smaller than the male penis. 17 However, this is true only for the spotted African Hyaena which distribution reaches Egypt.In the case of the striped hyena, there is no difficulty to distinguish between the male and the female genitals.According to this, it is possible that the Yerushalmi editors knew the spotted hyena or they drew their knowledge from the environment in which they lived.
