The sources of knowledge of two medieval Jewish commentators in nature issues: The case of gathering the musk (Song of Songs 5:1)

the information from Arabic writings, such as of al-Sir ā f ī and al-Mas ʿū d ī and Ibn Juljul. With regard to Na ḥ manides, his source of information on gathering musk is not clear. Contribution: This article contributes to the understanding of the issue of the sources of knowledge of scholars in medieval times and how the achieved information influenced their commentaries on the Biblical Text. The current study expounds the commentators’ interpretations from a multidisplinary perspective, such as the medieval zoology and perfume industry.


Introduction
Musk is an aromatic substance that over the generations has served as a perfume, spice and medicament.In ancient times, it was considered rare and to this day it has a place of honor in Far Eastern traditions.In the Middle Ages, musk was a well-known perfume throughout the Mediterranean region.Considerable documentation of its use appears in varied sources, such as books of geography, medicine, poetry and religion (On the uses of the musk according to the medieval literature, see Amar & Lev 2017:157-161;Ingram 2012: 175;King 2017:8).
Musk was a tradable commodity in the ancient world and it was exported from its natural habitat in the Far East to markets throughout the Mediterranean region, such as Spain, Eretz Israel and Egypt (On the musk's trade routes in medieval, see Akasoy & Yoeli-Tlalim 2007:217-240;King 2011King :145-162, 2017:85-146):85-146). Documents of medieval merchants indicate that musk was marketed in several forms: (1) as a fluid in glass vessels; (2) musk pods in their organic form, which were removed from the body of the mammal and dried and (3) as a solid, in packets or bottles (Blau 2006:199;Goitein 1973:50, 1983:vol. IV, 454;Goitein & Friedman 2013:115;Watt 1966: 786).
Musk is produced from the glands of several species of deer (the genus: Moschus) of which the most conspicuous is the Siberian musk deer (M.moschiferus), a cud-chewing mammal with no antlers that can be found in Siberia, Tibet and northern China.The male has long curved upper canines that protrude from the mouth.Under the belly, near the genitalia, is a pocket with special glands from which is secreted a soft viscous reddish-brown substance that has a sharp odour and bitter taste (Green 1987:307-319;Nowak 1991:vol II, 1364).The name 'musk' attached to this deer comes from 'muṣka', which means scrotum in Sanskrit (Shapira 1959a(Shapira :153-161, 1959b:185-187):185-187).

Both rabbis suggest that the operation of 'gathering' the biblical myrrh can be interpreted as indicating the unique manner of gathering the perfume of the musk deer, one that was customary in their time.
The main purpose of this article is to follow the sources of the knowledge of the two rabbis concerning the gathering of the myrrh and discuss their interpretations in light of parallel testimonies by non-Jews scholars who too describe the gathering of musk.R. Moses Ben Maimon (Maimonides, Spain andEgypt, 1138-1204) too identified myrrh with musk.When discussing the ingredients of the holy anointing oil that served to consecrate the priests and the temple vessels, he writes: 'Mor [=Musk] refers to the blood contained with a wild beast from India that is of universal renown which people everywhere use as a fragrance'. 1 Maimonides describes the musk as 'blood that is solidified (tzarur) within the animal', and this wording derives from the biblical phrase 'a sachet of myrrh' (tzror hamor) in Song of Songs 1:13.This may be associated with the fact that the aromatic substance is located or 'enveloped' within a 4 centimetres (cm) -7 cm long furry egg-shaped pocket (Maimonides 2002:hilkhot Klei ha-Mikdash, 1:3).

Identifying musk with the biblical myrrh by medieval sages
Several rabbis and modern researchers objected to the identification of biblical myrrh with musk.As an alternative, it was suggested that myrrh be identified with a perfume of vegetative origin, that is, the yellow-reddish crystalline resin produced from the trees of Commiphora abyssinica (Naḥmanidas 1959:vol. I, 496;Veizer 1976, The short commentary on Ex 30:23, 197-198). 2The following are the main arguments against identifying myrrh with musk: 1. R. Abraham ben David, the Ravad (Provence 1125-1198) rejected the identification with musk, claiming that musk is the blood of an impure animal that is unfit for ritual activity in sacred sites (Ravad 2002, hilkhot Klei ha-Mikdash, 1:3).However, this argument is untenable, as the musk deer boasts the necessary signs  [197][198].
Namely, the musk originates from the body of a 'gazelle' (tzvi) (see below) and the operation of harvesting or gathering is not relevant for substances produced from animals.
As claimed by modern researchers, the identification of the biblical myrrh with tree resin appears more logical, as attested by the various verses that link it to its habitat in the perfume gardens of tropical lands where exotic perfumeproducing trees grow (Song of Songs 4:14, 5:1; On the difficulties to identify the musk with the biblical myrrh, see Amar 2002:101-102).

The description of musk gathering in Ibn Aknin's commentary
The manner in which musk is gathered is described at length in the commentary written by R. Joseph Ben Judah Ibn Aknin (1150-1220) on the Song of Songs.Ibn Aknin was born in Barcelona, Catalonia.Being a converso, probably as a result of the Almohad persecutions, he (or perhaps his father) was compelled to leave his homeland and settled in the town of Fez in North Africa, and he remained there until his death.Ibn Aknin was a contemporary and friend of Maimonides, and he appears to have been a physician.He wrote dissertations on philosophy, medicine, biblical exegesis and Talmud, including a comprehensive Judeo-Arabic commentary on the Song of Songs (On the biography and works of Joseph ben Judah ibn Aknin, see Halkin 1944Halkin :27-37, 1963Halkin :93-111, 1964Halkin :11-12, 1971:501):501).
In the opinion of R. Joseph Ibn Aknin, the myrrh in Song of Songs 5:1 should undoubtedly be identified with musk.His interpretation may have been intended to reinforce Maimonides' interpretive approach, as according to his writings they were not only friends but rather Ibn Aknin was an ardent admirer of Maimonides (Halkin 1964:431).Ibn Aknin's interpretation is devoted to proving that ariya means the unique operation of gathering the musk in the musk deer's natural habitat.His words were of course intended to refute the claim that the biblical term ariya is more appropriate for the harvesting of myrrh resin.He writes (Halkin 1964): And ariti means 'I gathered'.Namely, I gathered and harvested.And some say that myrrh is a species of fragrant flowers because ariya is only used for plants that are gathered, and I say that it is musk, and this is unquestionable.And the word was borrowed for this purpose because it is taken from the gazelles as flowers are gathered from plants, since in the land of Tibet and China there are gazelles, and those in Tibet graze on aromatic and perfumed paths while those in China eat dry grass, and in these lands obstacles and snares are set for them and they are trapped.
And they are usually shot with arrows and knocked down and their myrrh bladders are cut off them while the blood is in the belly and has not matured and it is fresh and not weaned [=fully developed] and it smells very bad and is put aside until the bad odor dissipates and the putrid smells are transformed into musk.
And the best musk is that which matures in its vessels [=in its body parts] and is weaned in its navel and matured while still alive since nature pushes the blood substance to the navel and when the quality of the blood is ready and mature it causes the animal pain and itching.Then the gazelles flee to the rocks and stones that are hot from the sun and scratch themselves against them pleasurably and they open and spill onto these stones like bursting bubbles when their inner part becomes pus and they feel satisfied when it comes out and when emptied of the bladder's contents they are healed, and substances from the blood will push themselves into it [=and enter the bladder] as at first.Then the hunters go to them and head for their places of pasture and find the blood that has dried on those rocks by the sun and air and take it, and it is the choicest musk, and they put it in a bladder they took from fawns they captured, and this is the choicest musk, as written by the ancients concerning musk and we have conveyed this in their language.And if it is taken from the fawns [=gazelles] while hunting and it is not mature, then it is gathered from the stones, for this the word ariya was borrowed.(p.245) Ibn Aknin relates that musk is produced from deer found in Tibet and China, and he distinguishes between the two habitats -in Tibet, the deer graze on aromatic plants, whilst in China the deer feed on dry grass.In the ancient world, the Tibetan perfume was considered of the best quality (Amar & Lev 2017:157).The outlook whereby the origins of the musk fragrance comes from aromatic plants eaten by the deer was articulated by Naḥmanides.In his Iggeret ha-Kodesh [The holy letter], he writes: It is known that everything goes by the food, it affects the body.And research shows that the animal from which the myrrh is taken eats Al-sunbul' [from Arabic: ‫ُل‬ ‫ب‬ ْ ‫ُن‬ ‫=الس‬spikenard, Nardostachys grandiflora=N.jatamansi].(Naḥmanides 1955:329.See also Naḥmanides 1959:vol. I, 496) Accordingly, it appears that the Tibetan myrrh is considered choicer by virtue of eating aromatic plants.
According to Ibn Aknin's description, musk was produced in two ways.The first is by capturing the musk deer with traps or by shooting arrows.After it was captured, the 'bladder' [=the pocket in which the secretion is accumulated], located under the belly near the genitalia, was cut off.However, this generated perfume that did not reach a state of maturity, of poor quality with a bad odour.This perfume could not be used immediately and it had to be kept until the smell improved.
The second method, perceived as producing higher quality perfume, involved gathering the substance secreted naturally by the deer's body.According to Ibn Aknin, when the perfume matures it accumulates in the deer's navel.The maturation stage causes the deer to feel pain and itchiness, whereupon it scratches its belly on rocks warmed by the sun.The friction causes the deer pleasure and consequently the aromatic substance is secreted on the rocks (Compare to Naḥmanides' description below, who also notes that scratching the gland occurs specifically on hot days).The hunters or gatherers of the perfume, who are familiar with the phenomenon, detect the fluid that dries over time on the rocks and gather it in their vessels.
Zoologically, secreting the perfume on rocks as a result of 'a need to scratch', as understood by the ancients, indicates the spreading of aromatic substances for purposes of scent marking and intraspecific communication.Many mammals have secretion glands in various parts of the body, such as in the area of the anus, the groin, the stomach and the front of the eye.These glands are usually located in a pocket and there are two types: glands that secrete an aromatic substance and glands that secrete an oily substance that slows down the evaporation of the aromatic substance.
Aromatic substances (pheromones) are spread by mammals on rocks, trees, bushes, etc., in this way conveying different messages to others of their species.In the oestrus period, mammals secrete special aromatic substances and the production of aromatic substances increases (Alexander 1986: 96-97;Matthews & Knight 1963:103-108;Mendelssohn & Yom-Tov 1990:17).Ibn Aknin's description of the phenomenon as characteristic of hot days specifically is associated with the oestrus and mating season that occurs in the hottest season.The ancients probably identified the fluids secreted on the rocks as high-quality perfume because, as stated, at this stage the aromatic substances are special and intense.

Gathering musk in medieval Muslim sources -Ibn Aknin's sources
From where did Ibn Aknin derive his knowledge on the behaviour of the deer, and on capturing and gathering musk?Ibn Aknin notes at the end of his interpretation that he took the information on gathering the perfume from testimonies of 'ancients' and that he is bringing their words as said.He does not state explicitly what were his sources and his words are probably taken from Muslim writings of nature that closely describe the phenomenon.There are many similarities between the descriptions of Ibn Aknin and Al-Masʿūdī.Both refer to the production of musk in Tibet and China and note the superiority of musk originating from Tibet because the deer there feed on aromatic plants.They both distinguish between capturing the deer and cutting off the bladder, which produces lowquality musk, and choice aromatic musk secreted from the body after the maturation stage.They both similarly describe the physiological process that occurs in the deer's bodyblood that matures in the navel annoys the deer and causes it to itch. 3 They both note that rubbing against hot rocks leads 3.Compare to the words of Ibn Juljul (above) who relates that the gland becomes full of blood and then drips from the deer's legs.In contrast to al-Masʿūdī, Ibn to secretion of the pocket's contents and a sensation of relief from the itching.They both note that the natives gather the secreted substance from the rocks and stones and that it is considered very choice.
The similarity between the two descriptions indicates that Ibn Aknin probably derived his information from Al-Masʿūdī's book or from a later compilation based on it.Ibn Aknin understood the realistic descriptions in the writings of contemporary Muslim scholars as proof that the myrrh in the Song of Songs (5:1) is undoubtedly a choice perfume and that the manner in which it is gathered is compatible with the operation of ariya mentioned in the verse.

Ariya -Gathering musk according to Naḥmanides
The possibility that the operation of gathering musk is considered ariya is also mentioned in short in the biblical commentary of R. Moses Ben Naḥman (Naḥmanides 1194(Naḥmanides -1270)), one of the greatest Jewish sages who operated in Christian Spain in the middle ages.Naḥmanides, a commentator on the Bible and Talmud, thinker, kabbalist and physician, was born in Girona in northeast Spain.He completed his biblical commentary whilst living in Spain, several years before traveling to live in Eretz Israel in 1267 (On Naḥmanides, see Funkenstein 1980Funkenstein :35-59, 1991:164-168;:164-168;Halbertal 2006;Licht 1983:60-68).
Naḥmanides, in his interpretation of the ingredients of the holy anointing oil (Exodus 30:23), identified the biblical myrrh with Commiphora abyssinica.He argued that myrrh is not musk, as in rabbinical literature mor (myrrh) and musk (musk) appear as distinct terms.The midrash identifies mor as 'inmarinon', that is, the resin of the myrrh tree. 4In contrast, musk is a different term designating the perfume produced from musk deer (Jerusalem Talmud 1523: Berakhot 6:6, 10d; Babylonian Talmud 1882:Berakhot 43a).Moreover, Midresheiaggadah notes that myrrh is a perfume that becomes fragrant only once it is burned as incense (Song of Songs Rabbah 1885-1887:12a).This feature is typical only of the myrrh tree, whilst musk is fragrant even when not burned (Naḥmanides 1959:vol. I, 496; On the identification of the myrrh in the Bible, see Felix 1997:97).
Although Naḥmanides rejected the identification of the Biblical myrrh with musk, he raised the possibility that the unique manner of gathering musk is an operation that involves harvesting.In response to Ibn Ezra, who noted the difficulty of ascribing harvesting to an animal-based perfume, he wrote (Naḥmanides 1959): Perhaps [the scriptures] say 'I have gathered my myrrh' because this is blood that solidified within the belly of an animal that resembles a gazelle, which is common in the land of India, and when it treads among the bushes in days of great heat it scratches As we saw above, Ibn Ezra contends that musk is produced in the 'throat of the gazelle', but he does not state explicitly that this is blood.Naḥmanides, in contrast, explains that musk perfume is blood that accumulates in a gland in the belly of the 'gazelle' that is common in India.He also relates that on hot days the deer scratches the gland, whereupon the blood is excreted.At this time, those who gather the perfume go out into the fields and harvest it, which is why the operation is called ariya.Naḥmanides states that 'the blood emerges in a solidified form', indicating that it dries up from the heat and becomes solid, which explains the phrase tzror hamor [a sachet of myrrh] in Song of Songs 1:13.
From where did Naḥmanides derive his knowledge on the behaviour of the deer, and on capturing and gathering musk?He does not refer to his sources; however, part of his concise interpretation is based on widespread medieval geographical, zoological and physiological conceptions regarding the identity and habitat of the musk deer as well as regarding the essence and origins of the perfume produced from its body.The portrayal of the musk deer as a gazelle or an animal that resembles a gazelle that originates from India, and the perfume produced from it as 'blood', appears in the compilations of Muslim scholars in Spain (On the possibility that Naḥmanides derived his knowledge from Arabic sources, I shall discuss below).
An example of this is the short description by Andalusian physician Abu Dawud Sulayman ibn Hassan IbnJuljul (c.944 Córdoba-c.994), who provides information about musk when listing its medical qualities.He writes: misk -an Indian drug and it is a gland full of musk that falls from the legs of a beast the size of deer [gazelle].There are in their legs bulges that never stop growing and filling up with the blood of this animal, and when they filled up they fall off the animal, and the musk is inside, and some say that these bulges are in the intestines [correction: navel] of this animal.(The English translation of this passage is according to Amar, Lev & Serri 2014:549) India is the habitat of the Himalayan musk deer (Moschus leucogaster) (Singh et al. 2019:4-18).The geographical meaning of the term 'India' as utilized in rabbinical language may be wider than the country itself, encompassing the entire Far East.In any case, India (in addition to Tibet, China, and Turkey) was one of the centres from which musk was imported to Western Europe, including Spain (Akasoy & Yoeli-Tlalim 2007:217-240).
With regard to the nature and origins of musk, according to one approach held also by Naḥmanides, this is blood.Assumedly, musk was mistaken for blood because of its redbrown colour; however, we must stress that this secretion is unrelated to blood (see below).Other Jewish sages in Christian Spain described the aromatic product as 'sweat', that is, an animal secretion (Rabenu Jonah 1981:43a).
Another point discussed in Jewish medieval compilations is where in the deer's body is the perfume produced.Some claimed that the blood accumulates once a year in the deer's navel as a result of excess blood in its body (King 2017:162-164, 207-213).According to another tradition common amongst Jewish scholars in Christian Spain, such as in Rabenu Jonah who was a relative of Naḥmanides, the perfume is produced in the deer's neck (Asher ben Yeḥhiel 1981:28b;Rabenu Jonah 1981:43a), where some noted that it develops in a special pocket (Abudarham1878:92a).
The tradition concerning the origins of the perfume in the deer's 'belly' is closest to the truth, as the musk gland is located under the deer's belly near the genitals.The lack of clarity regarding the origins of the musk in the deer's body undoubtedly stemmed from the fact that the musk deer does not live in the Near East and the animal and its behaviour could not be observed directly.

Discussion and conclusions
Musk is not mentioned in the Bible and no historical source indicates that it was known in Eretz Israel at that time.In the Talmudic literature, it is mentioned in the context of the blessing recited over its fragrance, but we have no rabbinical source that identifies it with the biblical myrrh.In fact, only in the Middle Ages did biblical commentators begin to identify it with the biblical myrrh, and this appears to be associated with the fact that at this time musk became lucrative and was considered prestigious.It is to be assumed that the sages were influenced by the contemporary world of perfumes and were inclined to identify important perfumes with which they were familiar with superior perfumes mentioned in the Bible or ritual substances utilized in the temple.
The medieval identification of musk with the biblical myrrh or the myrrh mentioned in the rabbinical literature (Talmud and midrash literature) arouses two main questions -its incompatibility with the descriptions of the myrrh and its qualities.The incongruence discussed in the current article is that in the Song of Songs it is mentioned as a substance that is described as being gathered, a quality fit for a plant-based substance.Ibn Aknin, who supported the identification of biblical myrrh with musk, finds proof of its gathering in realistic descriptions of the musk industry in its lands of origin in the Far East.He contends that harvesting the perfume does not refer to capturing the deer and cutting off the pocket of perfume, rather to gathering the perfume that the deer spreads on the rocks naturally, which is a higher quality product.
The interpretations of Ibn Aknin and Naḥmanides are an example of medieval biblical interpretations based on later circumstances that were familiar to the commentator.As we have seen, the large geographical distance between the locations in which musk was produced in the Far East and the region of Europe and the Mediterranean Basin created information incongruities regarding the musk deer and the http://www.hts.org.zaOpen Access perfume produced from it.This fact explains the diverse opinions regarding the origin of the perfume in the body of the deer -in its belly, navel or neck.
Naḥmanides and Ibn Aknin were exposed to contemporary information and traditions with regard to how musk was gathered.However, there are many differences between them.Ibn Aknin read in Muslims books on the way of gathering the musk, and it is possible that this is the reason why his description is much lengthier and more detailed.
In the case of Naḥmanides, we cannot ascertain the source of his knowledge.As known from other contexts, Naḥmanides derived information for his commentaries and philosophy from several sources -personal experience and observation of his close environment (Naḥmanidas 1959:vol. II, 96), the books of non-Jewish sages (Naḥmanidas 1959:vol. II, 427-428) and conversations he conducted with contemporary non-Jewish scholars, for instance, diviners (Naḥmanides 1963:vol. I, 146). 5  Is it possible that Naḥmanides read about the musk deer and the way of gathering the perfume from Arabic sources?In fact, Naḥmanides was active almost his entire life in Christian Spain.Generally, in this region, Latin was the language of culture and religion, and the Castilian was the language of the street.On the other hand, in Muslim Spain, Arabic was the language of culture and religion, but also spoken vernacular (Lupovitch 2010:97).It is far from clear whether Nahmanides could read Arabic and this issue has been debated by various scholars (The question whether Naḥmanides could read Arabic has been debated by various scholars; see Unah 1976:10;Yahalom 2003:3;Yoshpe 1987:67-93).Moreover, he also definitely did not have access to the rich literature written in Arabic that Ibn Aknin had.
In Middle Ages, zoological information could be found in the European bestiaries (bestiarumvocabulum), a genre of animal books encompassing descriptions and explanations 5.Ezra Zion Melamed stated that the grounds for Naḥmanides' exegesis is the knowledge he acquired in various ways: personal experience, life circumstances, studies, and encounters with rabbis and scholars (see Melamed 1978:954-957;Shemesh 2019:93-119).
on a variety of animals (some real some legendary), together with illustrations and morals related to each animal (Baxter 1998:83).These books were popular in medieval England and France and were also found in Spain (On Latin, English and French Bestiaries manuscripts, see McCulloch 1960:1-25;Stewart 2012:93-110;White 1960; On Bestiaries in medieval Spain, see Baldwin 1982Baldwin , 2013: 164-165): 164-165).The musk deer is described in this literature, but it seems in a limited manner (see Figure 1).In any case, there is no evidence that Naḥmanides used this literature.
Some of the first descriptions of musk deer and of how the perfume was produced are those of Al-Sirāfī, Abū Zāyd who lived in the beginning of the 10th century (Al-Sirāfī 1999:75-77), Al-Masʿūdī ibn al-Ḥusayn who died in 956(Al-Masʿūdī 1962-1997:vol.I, 98)and Ibn Juljul ibn Ḥasān who I have mentioned before.Anya King has already spoken about the similarity between the descriptions of al-Sirāfī and al-Masʿūdī and raised the possibility that they had met in person and exchanged information about the musk deer(King 2017:168).Al-Masʿūdī's description was the source for many later descriptions of musk deer and it was utilized, amongst others, by the Andalusian, botanist and physician, Ibn al-Bayṭār al-Mālaḳī and by the Persian-Baghdadi physician and geographer Al-Qazwīnī, Zakarīyā ibn Muḥammad (1203-1283) (Al-Qazwīnī 1967:vol.I, 383; Ibn al-Bayṭār al-Mālaḳī 1874:vol.IV, 155-156).
http://www.hts.org.zaOpenAccessTheland which has musk gazelles is in Tibet and China[…].Tibetan musk is superior to Chinese musk for two reasons.First, the musk gazelle which is in the territory of Tibet has grazing lands of spikenard and various types of aromatic plants […] The other respect is that the people of Tibet do not bother to remove the musk from the vesicle and they leave it as it is within it […] The best and most fragrant musk is that which comes out from the gazelle after it has reached the end of its maturation[…]In Tibet and China they set up snares and nets for them and they trap them.Sometimes they shoot arrows at them and fell them.Then they cut the pods from them.The blood which is in the navel is raw and not matured and fresh and not ripened.It has a stench for its scent.They leave it for a time until that stinking, offensive odor has left it […] The best musk is what matured in its vessel and ripened the navel […] To be precise, natural forces push the matter of the blood to his navel.When the blood has matured and ripened within, it bothers the animal, and it causes him to scratch, so he seeks refuge at stones or rocks warmed by the heat of the sun and there rubs himself on them finding relief through that then it [=the navel] bursts forth and it [=the musk] flows upon those rocks as an abscess or boil bursts when whatever matter has collected in it successively has matured.
and the blood emerges in a solidified form and it is gathered [by people] from the pasture.(vol.I, p. 496) Juljul doesn't mention the phenomenon of itching and the deer's rubbing against the rocks.4.According to R. Benjamin Ben Emanuel Musafia (Spain and Netherlands 1606-1675), 'oinomyrines' (οίνμυρίνης) is wine mixed with myrrh and spices (see Musafia 1955:vol.I, 150).http://www.hts.org.zaOpen Access that swelling [=swollen gland], Halkin (1971)m a completely different time and place and they were influenced by a different cultural environment.As we have seen Ibn Aknin reports that he took his information from the work of Arab scholars.Ibn Aknin spent most of his life in North Africa, presumably Fez, Morocco.He lived in Arab lands and clearly was well schooled in all areas of knowledge available there.He knew the Arabic language, read Arabic literature and was influenced by Arab scholars.As Abraham SolomonHalkin (1971)writes:Aknin is typical of a group of intellectuals in the Jewish community under Islam that was impressed with the learning and doctrines of Greek and Hindu origin cultivated by Muslim intellectuals.However, he saw no conflict between his religious and secular learning.(p.501)
