History Of Medicine In The Islamic Civilization

Medieval Islamic doctors
Prophet Muhammad’s words, “Your body has rights over you” paved their way to amazing advancement in the medical, pharmaceutical, and health fields.

By Amira Ayad

For early Muslims, knowledge was a treasure they would eagerly seek. Medical science and pharmacy were no exceptions.
Muslim physicians’ early practice emphasized the importance of preserving health through natural gentle interventions. The Hippocratic philosophy of ‘Premium non nocera’(first don't harm) was a well kept notion in their minds as it reflected the teaching of their religion. Prophet Muhammad’s words, “Your body has rights over you” (agreed upon - Ṣaḥīḥ al-Bukhārī) paved their way to amazing advancement in the medical, pharmaceutical, and health fields.
Studying history, we can see that medicine within the Islamic civilization passed through three main stages (Abouleish, n.d.). The first stage started in the early 7th century by collecting and translating the medical knowledge of the Greeks, Persians, Assyrian Syriacs, Indians and Byzantines. (Nagamia, 1998)
Soon enough, Muslim physicians started to elaborate on the collected body of knowledge and largely expanded it through experience, exploration, experimentations, testing, and practice. This was during the Golden Age of the Islamic civilization that brought the original contributions of Muslim physicians in the medical, pharmaceutical, herbal, nutritional and botanical fields. This second stage extended during the ninth through thirteenth centuries. During the last stage, however, decline occurred which reflected the stagnation and gradual deterioration of the whole Islamic nation.
During the second stage, many physicians, Arabs as well as non-Arabs, contributed to the flourishing of the medicine. Physicians like Al-Razi, or Razes (841 – 926 AD), and Ibn-Sina, known as Avicenna (980 – 1037 AD) were pioneers in the medical fields. Their books and teachings were used as bases for medical study in Europe for centuries to come.
Al-Razi’s fame started with the establishment of a hospital in Baghdad in the 9th century which included a special ward for mental illness. He also pioneered in holistic and spiritual medicine, advocating healing and caring for the whole patient. This idea was well reflected in his book ‘Al-Tibb al-Rawhani’ (Spiritual Medicine) where he emphasized the importance of heart purification and ethical and virtuous conducts in achieving total healing.
In his famous book, Al-Qanun fi al-Tibb (The Law in Medicine), Ibn-Sina laid the foundation of medical practice, compiled a complete Materia Medica, described diseases and malfunctions  and gave a full formulary of remedies, suggestions and recipes for treatment.
Balancing Body

The eye according to Hunain ibn Ishaq. From a manuscript dated circa 1200.
As early as the 10th century, Muslim physicians were treating eye diseases and even performing cataract surgery. Al-Mawsili, an Iraqi ophthalmologist and physician, designed a special needle to remove cataract by suction. And, an amazingly complete text book on eye disease ‘Notebook of the Oculist’ was written by Ali Ibn Isa also in the 10th century Baghdad. On Ibn Isa’s valuable reference was based the European knowledge of modern ophthalmology. (Al-Hassani, 2006)
Ibn al-Nafis, the Syrian Muslim scholar, described in a treatise written in 1210 AC the role of the heart and lung in blood purification and elaborated on Ibn-Sina’s description of the pulmonary circulation. Ibn al-Nafis accurately described the anatomical structure of heart chambers and the fine structure of the circulatory system hundreds of years before Western discoveries.
Early Muslims also laid the foundation of modern day pharmacology through the early work of Sabur ibn Sahl, Al-Razi and Ibn-Sina in the early 9th century. Later on, in the 11th century, Al-Biruni wrote his famous master piece ‘The Book of Pharmacology’ compiling an amazing work on drugs and remedies. Al-Zahrawi’s writings ‘Al-Tasrif’(Dispensing) further taught methods of drug preparations and formulation starting from simple remedies all the way to complex compounding. (Al-Hassani, 2006)
The principal concepts embodying medicine as practiced during this period were based on the essential meaning of balance. They presented the physician’s role as one of in balancing and harmonizing overall bodily functions while restoring health and healing on the physical, emotional, mental and spiritual planes.
Physical ailments were thought to arise mainly as a result of accumulation of excess waste substance in the body. Overeating, improper food choice and other unhealthy habits were regarded as the source of the accumulated morbid matter, and a disease’s symptoms appears when the digestive process becomes overwhelmed. (Al-Jauziyah, 2003)
More importantly, however, it was the fundamental belief of a Muslim physician that the physical body should never be the sole interest of the physician. It is the Ruh, or soul, which gives this body its vitality and true essence. (Nagamia, 1998) It was thus essential for a Muslim physician to be well aware of the diseases of the heart and soul and how to treat them along with managing physical symptoms.
Mixed Approach
islmc-medicine201111
“Whenever it is possible to use gentle remedy, do not use something powerful instead,”
During the third stage of this thriving medical history within the Islamic world, and around the fourteenth century, a new type of medical writing emerged. The authors were religious scholars, rather than physicians. Their aim was to preserve the wealth of knowledge and heritage compiled and practiced by Muslims over the years from fading away before the rapidly rising Western society. (National Library of Medicine, 1998)
Their writings all carried the same title:Al-Tibb Al-Nabawi (Prophetic Medicine) and was intended as an alternative to the Greek-based medical science. Most famous among them were the writings of Al-Jauziyah, As-Suyuti, and Az-Zahabi which are considered as the base for what is today referred to as ‘Islamic Medicine.’
Al-Jauziyah’s recommendations for approaching the patient reflected the preserved notion of balance and holistic approach taught by early Muslim physicians. He advised physicians to investigate all areas of their patient’s life, research the real cause behind the disease, examine the patient’s feelings, mood and life style and consider dietary options before resorting to drugs. (Al Jauziyah, 2003)
The physicians were knowledgeable about the ‘sickness of the heart and soul’ and took great care when approaching them in a professional yet caring manner. They realized the effects of stress, emotions and mental state, and used positive affirmations from Qur’an and Prophetic Sunnah to increase hope and strengthen the will for healing.
Moral values, love, courage, patience, kindness, and altruism were prescribed as the best remedies for the inner self, and prayer was practiced for maintaining the connection with God, preserving the health of the body and soul, strengthening faith, bringing happiness and energizing the body against acute ailments. (Ayad, 2008)
The six primary channels that should be balanced to avoid contacting diseases, as stated by As-Suyuti, further reflected the wisdom of early Muslim knowledge. He emphasized the importance of the quality of air we breathe, food and drink we consume, physical exercise and movements, our emotional state and feelings, our sleep and waking cycles, and our body’s ability to excrete toxins, get rid of accumulated morbid matter and retain valuable nutrients.
“Whenever it is possible to use gentle remedy, do not use something powerful instead,” he wrote, advising a physician to be “gentle in his speech, kind in his words and close to God.” (As-Suyuti, 2009)
Az-Zahabi, on his side, recommended using only medicines that are similar or related to regular food and that contained no noxious or harmful substances. (Az-Zahabi, 2004)
Starting from the beginnings of the seventeenth century, Islamic Medicine was challenged by rapidly spreading science of conventional modern medicine, which eventually replaced the core of the health care systems in most of the Islamic countries (Nagamia, 1998).
Contemporary practice of Islamic Medicine is restricted to India, Pakistan and Bangladesh where one can find established medical schools teaching this type of medicine, certified and supervised by the Indian Medical Council. (Nagamia, 1998) And while these schools do teach such medical approach while being highly influenced by the teachings of the old Greek practice, it is also common to find conventional physicians in Middle Eastern countries and Malaysia giving medical advice and some treatment while making use of the Islamic approach. Some believe that this mixing of the old and the new, the eastern and the western, makes their patients benefit from ‘the best of both worlds.’

Muslim Scientific Achievements

Al-Biruni

By David W. Tschanz

Arabic pharmacy (Saydanah)* as a profession and school of thought separate from medicine was recognized by the beginning of the ninth century CE (third century AH). Baghdad, the center of learning at the time, saw a rapid expansion of the number of privately owned pharmacy shops, a trend that quickly spread to the suburbs and other Muslim cities.
Traditional Pharmacy vs. Modern Pharmacy
The traditional style of pharmacy was modeled after the pharmacies of the IslamicWorld (still popular in Egypt). The style of the modern pharmacy has not changed much from back then. However, the traditional pharmacies were responsible for mixing their own pharmaceuticals. Nowadays, the mixing is done in factories and more chemicals are used rather than natural herbs and ingredients.
The pharmacists who managed these new shops were skilled in the apothecary's art and quite knowledgeable in the compounding, storing, and preserving of drugs. State-sponsored hospitals also had their own dispensaries attached to manufacturing laboratories where syrups, electuaries, ointments, and other pharmaceutical preparations were prepared on a relatively large scale.
A government appointed official, al-Muhtasib, and his aides periodically inspected the pharmacists and their shops. These state inspectors were responsible for assuring the accuracy of the weights and measures as well as the purity of the materials used to make the drugs. This served as a means of assuring quality and safeguarding the public.
This early rise and development of professional pharmacy in Islam -over four centuries before such development took place in Europe- was the result of three major occurrences: the great increase in the demand for drugs and their availability on the market; professional maturity; and the intellectual curiosity.
The ninth century marked the beginning of the Golden Age of Islamic learning, and just as Muslim scholars made significant gains in the physical sciences, so too did they learn, master and expand the arts of medicine and the science of pharmacy.
The prolific intellectual ferment that fired the Baghdad schools, support at the highest levels of government, and a craving for intellectual pursuits paved the way for a still greater harvest in the succeeding four centuries. Manuals on materia medica and references for instructing the pharmacist concerning the work and management of his shop began circulating in increasing numbers.
One of the contributors to Arabic pharmacy in the third/ninth century was the Nestorian physician, Yuhanna bin Masawayh (known in the West as Mesue, c.777-857). A second-generation pharmacist, Ibn Masawayh penned an early treatise on therapeutic plants, listing about thirty aromatics - including their physical properties, methods of detecting adulteration, and their pharmacological effects.
European depiction of Abu Bakr Al Razi. (Latin version: Gerard Cremona).
On ambergris, for example, he explains that there are many types, the best among them the blue or gray (gray-amber) and that fatty as-salahiti is used with the choicest of aromated mixtures (ghaliyyahs, perfumes, or medical cosmetics). Ibn Masawayh also recommended saffron for liver and stomach ailments.
He noted that sandalwood, whether yellow (the best), white, or red is brought from India where it is used in the manufacture of perfumes.
In his medical work, Ibn Masawayh recommended the use of well-known medicinal plants to build up a natural resistance to diseases. He urged physicians to prescribe one remedy for each disease, using empirical and analogous reasoning. He finally stated that the physician who could cure by using only diet - without drugs - was to be considered the most successful and skilled.
Another of Ibn Masawayh's books, Al-Mushajjar al-Kabir, is, to some extent, a tabulated medical encyclopedia on diseases and their treatment via drugs and diet. Other works are comprised of small treatises - such as one on barley water, explaining how to prepare it and its therapeutic uses.
A countryman and younger colleague of Ibn Masawayh was Abu Hasan 'Ali b. Sahl Rabban at- Tabari born in 808. At about thirty years of age, he was summoned to Samarra by Caliph al-Mu'tasim (833-842), where he served as a government officer and a physician.
At-Tabari wrote several medical books, the most famous of which is his Paradise of Wisdom, completed in 850. In addition to discussions on diseases and their remedies, the book contains discussions on the nature of man, cosmology, embryology, temperaments, psychotherapy, hygiene, diet, medical anecdotes, and abstracts and quotations from Indian source material.
The work also includes several chapters on materia medica, cereals, diets, utilities and therapeutic uses of animal and bird organs, as well as drugs and methods of their preparation.
At-Tabari urged that the therapeutic value of each drug be reconciled with the particular disease, urging physicians not to fall prey to the routine remedy. He identified the best source for several components, stating that the finest black myrobalan comes from Kabul; clover dodder from Crete; aloes from Socotra; and aromatic spices from India.
He was also precise in describing his therapeutics, e.g.:… a very useful remedy for swelling of the stomach; the juices of the liverwort (water hemp) and the absinthium after being boiled on fire and strained to be taken for several days.
Jabir ibn Hayyan by an Egyptian artist.
Also powdered seeds of celery (marsh parsley) mixed with giant fennel made into troches and taken with a suitable liquid release the wind in the stomach, joints and back (arthritis).
For storage purposes he recommended glass or ceramic vessels for liquid (wet) drugs; special small jars for eye liquid salves; and lead containers for fatty substances. For the treatment of ulcerated wounds, he prescribed an ointment made of juniper-gum, fat, butter, and pitch. In addition, he warned that one mithqal (about 4 grams) of opium or henbane causes sleep and also death.
The first medical formulary to be written in Arabic was by al-Aqrabadhin tly Sabur bin Sahl (d. 869). In it, he gave medical recipes stating the methods and techniques of compounding these remedies; their pharmacological actions; the dosages given of each; and the means of administration.
The formulas are organized in accordance to the types of preparations into which they fit, - whether tablets, powders, ointments, electuaries or syrups. Each class of pharmaceutical preparation is presented along with a variety of recipes made in a specific form; they vary, however, in the ingredients used, their recommended applications, and therapeutic effects.
Sabur's formulary-type compendium is unique in its organization and purposely written as a guidebook for pharmacists, whether for use in their own private drugstores or in hospital pharmacies. As such, it is the first true medical formulary.
A few books related to pharmacy were written by the famous scholar, Ya'qub bin Ishaq al-Kindi (d. 874). His contributions to philosophy, mathematics and astrology, however, were greater than those on medicine and therapy. Nevertheless, it is to his credit that he was an outspoken critic of alchemists and attacked their procedures and claims as deceptive under the circumstances.
Hunayn's book of the Ten Treatises on the Eye was completed in 245/860. After finishing the first nine treatises, the author felt the need for a closing treatise to be devoted to compounded drugs for eye medication.
In addition, as one example of the uses and therapeutic values of using compounded drugs, Hunayn gave the example of theriac, the universal antidote against poisoning. Hunayn, whose translations were literally worth their weight in gold, translated into Arabic the major part of Dioscorides' Materia Medica, undertaken by his associate Istifan bin Basil (in the mid ninth century). As a result, several books of materia medica were written in Arabic.
* In Islam, sandalwood first appears in pharmaceutical preparations in the early eighth century, or perhaps earlier. It soon became associated with the profession: and pharmacists were called as-saydanani or as-saydalani (he who sells or deals with sandalwood), and the word savdanah referred to a pharmacy.

Hunayn Ibn Ishaq: The Greatest Translator Of The Islamic Golden Age



Hunayn ibn Ishaq known in Latin as Johannitius is considered as one of the most influential scholars of the ninth century who contributed so richly in fields like medicine and science during the zenith of the Islamic Abbasid Caliphate.

By Fred Aprim

It is written that it would be a rearity to find any Arabic translation of the most popular Greek medicine and philosophy publications without discovering that Syriac was the mean through which the translation took place. Most of the Greek work was translated to Syriac first and then from Syriac into Arabic language.

Hunayn bin (son of) Ishaq's (Iskhaq in Syriac / Isaac in English) outline of life and work are well known from his autobiography written in the form of letters to 'Ali bin Yahya. (Text from two manuscripts in the Aya Sofia Mosque at Istanbul, with translation by G. Bergestrasser, Leipzig, 1925) He was a native of Hira, near Baghdad, and the son of a Nestorian druggist (Pharmacist). He is endorsed by his name 'Abadi, which shows that he belonged to the subject people of Hira. Hunayn followed in the footsteps of other Nestorian physicians like Jirgis (Giwargis) bin Bakhtishu (ca. 771) the dean of the Jundi-Shapur hospital (south-western Persia). Jundi-Shapur was noted for its academy of Medicine and Philosophy founded about AD 555. Nothing is known though of the Bakhtishu who was the father of this Jirjis, but the name occurs several times in the course of the history of Baghdad.

In AD 765 the Caliph Al-Mansur, afflicted with a stomach disease which had baffled his physicians, summoned for Bakhtishu, who soon won the confidence of the caliph and became the court physician, though he retained his Nestorianism. Invited by the caliph to embrace Islam his retort was that he preferred the company of his fathers, be they in heaven or in hell. Bakhtishu became in Baghdad the founder of a brilliant family which for (6) or (7) generations, covering a period of (2 1/2) centuries, exercised an almost continuous monopoly over the court medical practice. Jibril (Gabriel) bin Bakhtishu, in AD 801 became chief physician of the Baghdad hospital under the Caliph Al-Rashid and in AD 805 the caliph's private physician until his death in AD 829. The Bakhtishu family played an important part in the cultural education of the Arabs.

Hunayn in AD 857 as a youth began as a dispenser to Yahya (Youkhanna) Bin Massawayh, the great doctor and pupil of Gabriel bin Bakhtishu. Massawayh, is said, having been fed up with Hunayn's continuous questioning, have said to him:"What have the people of Al-Hira have to do with medicine?--go and change money in the bazaar." (read Ibn al-'Ibri, p. 250) The young Hunayn left the service of Masawayh in tears, but challanged himself to study Greek in "the land of the Greeks" where he stayed for (2) years and obtained a sound knowledge of the Greek language and familiarity with textual criticism such as had been developed in Alexandria. Later he settled for some time at Basra and attended the popular school of Al-Khalil bin Ahmad (Al-Faraheedi) and there he became fluent in Arabic before returning to Baghdad in AD 826. He was then introduced by Gabriel bin Bakhtishu (now physician-in-ordivary to caliph Al-Ma'mun) to Musa bin Shakir and his sons, known as "Sons of Musa", wealthy patrons of learning. Subsequently this caliph founded a library-academy which he called the "House of Wisdom" (Dar Al-Hikma) and appointed Hunayn as its superintendent. In this capacity Hunayn had charge of all the scientific translation work, in which he enjoyed the collaboration of his son Ishaq bin Hunayn and his nephew Hubaysh bin Al-Hasan, whom he trained. Hunayn's ability as a traslator may be attested by the report that when in the service of the sons of bin Shakir he and others received about 500 dinars (about £ 250) per month and that Al-Ma'mun paid him in gold the weight of the books he translated.

Al-Ma'mun died in AD 833 and was succeeded by Al-Mu'tasim, who found it difficult to control the populace of Baghdad and formed a guard of Turkish slave-soldiers. But this body-guard, holding a privileged position, soon became insubordinate and many complaints were made about their conduct. At last Al-Mu'tasim removed himself and his court to Samarra (north of Baghdad) in AD 836, and there the caliphs reigned until AD 892. These disorders affected scholarship adversely and the "House of Wisdom" fell into decay which was not checked during the brief reign of Wathiq (AD 842-847). The next Caliph was Al-Mutawakkil (847-861), although he was bigoted, fanatical, and sadistic, he was a generous patron of scientific research and is generally reckoned as having reopened the "House of Wisdom". It was during this Caliph's reign where Hunayn reached the summit of his glory not only as a translator but as a practitioner when he was appointed by the Caliph Al-Mutawakkil as his private physician. Al-Mutawakkil, however, once committed him to jail for a year for refusing the offer of rich rewards to concoct a poison for an enemy. When brought again before the caliph and threatened with death his reply was:
"I have skill only in what is beneficial, and have studied naught else".


Asked by the caliph, who then claimed that he was simply testing his physician's integrity, as to what prevented him from preparing the deadly poison, Hunayn replied:
"Two things: my religion and my profession. My religion decrees that we should do good even to our enemies, how much more to our friends. And my profession is instituted for the benefit of humanity and limited to their relief and cure. Besides, every physician is under oath never to give anyone a deadly medicine." (read Ibn al-'Ibri, pp251-252)

In AD 861 Al-Mutawakkil was murdered by his Turkish guards at his son's instigation. Hunayn enjoyed the favour of that son Al-Montasir (AD 861-862), and his successors Al-Mosta'in (AD 862-866), Al-Mo'tazz (AD 866-869), Al-Muhtadi (AD 869-870), and Al-Mu'tamid (AD 870-892), and was engaged in making a translation of Galen's De constitutione artis medicae at the time of his death, which took place in 873 according to the Fihrist, or 877 according to Ibn Abi Usaibi'a.

Of the numerous works ascribed to Hunayn, some should undoubtedly be credited to his two assistants, his son and nephew, and to other students of his school, such as 'Isa bin Yahya bin Ibrahim (Essa Youkhanna Oraham), and Musa (Moshe) bin Khalid. Almost all the leading scientists of the succeeding generation were pupils of Hunayn like Staphanos bin Basilos, who translated the Dioscorides into Syriac, and this Syriac version was then translated into Arabic by Hunayn himself for the "Sons of Musa". In many cases Hunayn evidently did the initial translation from Greek into Syriac and his colleagues took the second step and translated from Syriac into Arabic.


Aristotle's Hermeneutica, for instance, was first done from Greek into Syriac by Hunayn, the father, and then from Syriac into Arabic by the son Ishaq, who was the better in Arabic and who became the greatest translator of Aristotle's works.


Altogether Hunayn translated into Syriac (20) books of Galen, (2) for Gabriel Bakhtishu's son, (2) for Salmawaih bin Bunan, (1) for Gabriel Bakhtishu, and (1) for bin Massawayh, and also revised the (16) translations made by Sargis Al-ras'ayni of Ras Al-'ayn on the Khabur River, who translated the famous "Corpus Galena".

Rainer Degen, of Marburg wrote a paper on the oldest known Syriac Manuscript of the greatest Nestorian translator and physician Hunayn bin Ishaq, after his return from a trip to Paris in 1973, and Baghdad in 1974, where he attended the great festivals in commemoration of the 1100th year of the death of this great Nestorian. Anton Baumstark wrote so much about Hunayn in Aristoteles bei den Syrern vom V. - VIII. Jahrhundert. Syrische Texte. 1. Band: Syrisch-arabische Biographien des Aristoteles / Leipzig 1900, and classified him as "der gröBte aller syrischen Gelehrten des Mittelalters".


Degan writes; "Not a single paper about Ishaq's Syriac works was read in both Paris and Baghdad, where various aspects of Hunayn's life and work were treated by the learned speakers, the Syriac part of his works played only a minor role. (Read the presented papers in Baghdad under a volume entitled "Ephraim Hunayn Festival. Baghdad 4-7/2/1974, published by Al-Ma'arif Press, 1974)."


What would we expect from the authorities in Iraq? A government which has adopted the policy of Arabization in all aspects of the Christians' life, But to have the same happen in Paris is the part we find hard to believe!


Degen started in 1971 to collect all the available information about the remains of Syriac medical texts for the planned 'Corpus Medicorum Syriacorum,' and he got a microfilm from the Vatican Library in which he found that what the two S.E. & J.S. Assemani had written in "Bibliothecae Apostolicae Vaticanae codicum manuscriptorum catologus, partis Iae t. 3, complectens, reliquos codices chaldaicos sive syriacos," Rome 1759, p. 409, Vatican Syriac 192, describing the content of the work of Paul of Aegina's misleading titled "Syntagma medicum" was totally wrong. The book " Syntagma medicum" is not a translation from a Greek original, but the oldest Arabic manuscript of the famous "Book of Medical Questions for the Beginners" [widely known in Arabic as 'Kitab al-Masa'il al-Ttibbiyah'] by Hunayn bin Ishaq. This book was used in the 16th century as the best introductory work in medicine.


One of the oldest Syriac manuscripts is to be found in the Mingana Collection in the Selly Oak Colleges Library, Birmingham. Its number is Mingana Syriac 661. The Catalogue does not say from where Alphonse Mingana acquired the manuscript, but in a note on page XXI somebody, perhaps Dr. Gottschalk, mentioned after Mingana's death that "Dr. Mingana was also convinced that the Syriac MSS. Nos. 628-662 came from Mount Sinai." According to A. Mingana this manuscript is "written in an early East Syrian [Assyrian] hand bordering on a West Syrian [Assyrian] sirta of about AD 1100."


Degen asks: But, from where do we know that the text of the leaves is Hunayn's?
Because Degen found the contents of that manuscripts in a similar Syriac manuscript in Mingana's Collection: Syriac 594 which is a modern copy of a likewise modern manuscript in Alqosh. When Degen got the microfilm of the Arabic manuscript Khudabakhah 2142/1 (preserved in the Oriental Public Library, Patna / India), he was able to identify the author of the Syriac work. The mentioned Arabic manuscript is the only one that preserved a once widespread and famous treatise -- the book of Nourishment (Kitab al-Aghdiya) -- of Hunayn bin Ishaq.

Some of Hunayn's Translations:

Lake Natron Turns Animals To Stone

While traveling northern tanzania for a pictorial journey of east africa, british photographer Nick Brandt unexpectedly came upon a number dead birds and bats that appeared to be made out of stone. the animals had washed up along the shoreline of the lethal lake natron, a salt lake located near the kenyan border. the waterway contains a deadly chemical composition — a very high soda and salt content — which causes any creature who dares to dip in to die, calcify, and remain perfectly preserved as they dry. brandt notes that the chemical level was so extreme, that while he was capturing the images, the ink stripped off his kodak film boxes within just a few seconds.

The mummified species are the eerie aftermath of nature’s nightmarish unpredictability. for his monochrome portraits, brandt carefully removes the found birds from the water and places them in living positions, perching them on branches, and arranging them as floating figures on the stagnant shore. the posed compositions reanimate the lifeless animals, alive again in death. brandt has sent designboom images of the series of inanimate animals, which you can see below:

How Spiders Keep The Peace

The Parawixia bistriata (pictured), a large spider that lives in the semiarid habitats of southern Brazil, knows that when it comes to living in a crowded neighborhood, fighting is never the answer. 

Scientists knew that communities of P. bistriata emerge from collective shelters at sunset and build individual webs along permanent and communal silk support lines. 

At the end of the night, however, a small number of webless spiders peacefully share the prey of their neighbors—a rare instance of cooperation among arachnids. 

Now, after months of observation, researchers have developed a new model explaining the behavioral strategies of these webless spiders. 

Once the sun begins to set, P. bistriata swarm the communal silk lines, searching for spots to build their webs. As each spider claims its territory, it shoos away others that try to settle uncomfortably close by. Early in the evening, the still-webless interlopers graciously move on, knowing that they will likely find an empty spot elsewhere. But as the night progresses, desperation sets in. Open sites become scarce, so webless spiders no longer retreat when resident spiders bounce up and down to drive them away. Instead, they sit near a resident's web and freeload on large prey—seemingly with the resident's permission. 

Applying insights from game theory, the researchers concluded that resident spiders don't aggressively defend their territory because a night's meal is not worth risking their lives in a fight, they report this month in The American Naturalist

What's more, any spider could find itself on the other side of the negotiation the next night, when the race for space begins again.

Mamihlapinatapai




Derived from the Yaghan language of Tierra del Fuego, listed in The Guinness Book of World Records as the "most succinct word", and is considered[who?] one of the hardest words to translate.
A slightly different interpretation of the meaning also exists: "It is that look across the table when two people are sharing an unspoken but private moment. When each knows the other understands and is in agreement with what is being expressed. An expressive and meaningful silence."[2] It is also cited in books and articles on game theory associated with the volunteer's dilemma.
The word consists of the reflexive/passive prefix ma- (mam- before a vowel), the root ihlapi (pronounced [iɬapi]), which means to be at a loss as what to do next, the stative suffix -n, an achievement suffix -ata, and the dual suffix -apai, which in composition with the reflexive mam- has a reciprocal sense.
Yagán (originally Yahgan, but also now spelled Yaghan, Jagan, Iakan), also known as Yámana and Háusi Kúta, is one of the indigenous languages of Tierra del Fuego, spoken by the Yagán people. It is regarded as a language isolate, although some linguists have attempted to relate it to Kawésqar and Chon.
Along with other Fuegian languages, it was among the first South American languages to be recorded by European explorers and missionaries[citation needed]. Yahgan was also spoken briefly on Keppel Island in the Falkland Islands at a missionary settlement.
Tierra del Fuego (pron.: /tˈɛərə dɛl ˈfwɡ/Spanish: [ˈtjera ðel ˈfweɣo]; Spanish for "Fireland" or "Land of Fire") is an archipelago off the southernmost tip of the South American mainland, across the Strait of Magellan. The archipelago consists of a main island Isla Grande de Tierra del Fuego divided between Chile and Argentina with an area of 48,100 km2 (18,572 sq mi), and a group of many islands including Cape Horn and Diego Ramírez Islands. While initially discovered by Ferdinand Magellan's expedition in 1520, it was not settled by people of European descent until the second half of the 19th century at the height of the sheep farming and gold rush booms. Today, petroleum extraction dominates economic activity in the north of Tierra del Fuego, while tourism, manufacturing and Antarctic logistics are important in the south.
