Magical Metal

Yesterday mentioned the gold and silver cramp rings used in the Middle Ages in England to avoid cramps and epilepsy. (The sample here—alas!—is a later iron version.) Gold and silver were precious not only for their rarity and beauty; it was the reason for their beauty that made them magical.

Gold and silver do not oxidize like iron and copper. This "metallic immortality" surely helped to enhance the idea that they were special in a magical way. In fact, gold was considered medicine by many early authorities.

An 11th century lecturer at Salerno, Constantinus Africanus, claimed:

Gold is more temperate than the other metals. It has the property of relieving a defective stomach and comforts the fearful and those who suffer from a heart complaint. Galen confirms that it is effective against melancholy and baldness.

 Obviously gold needed to be ingested for it to work. To do so required very small pieces, and the Arab physician Abulcasis explained the method for preparing gold for consumption:

Take a piece of good and pure gold; and have a plate with pure sweet water in front of you; and have a rough clean cloth of flax, one end of which you keep in your hand. The other end should stay soaking in water on the bottom of the plate. Then rub gold with the cloth, always moistening the cloth with water, and fine filings descend to the bottom of the container. Do so as long as much of that gold as you want to have been shaved. Then leave for an hour; and mix water speedily and wash three times and dry up and preserve it.

Gold-based preparations were called aurum potabile ("drinkable gold"), written about by Michael Scot, Roger Bacon and others. Making it drinkable was no small trick, but it could be made into a liquid by combining hydrochloric acid and nitric acid. This mixture was one of the only ways to dissolve gold, and inspired alchemists to believe that an actual, pure aurum potabile was possible. Paracelsus (1493 - 1541), who was adamant that one could improve upon Nature, and his contemporary Johan Isaäc Hollandus were certain that pure liquid gold could be achieved and would have unbelievable curative properties.

The consumption of gold over time, however, far from enhancing health produced "auric fever": fever, profuse sweating, excess urination, gastrointestinal problems, and kidney damage. Evidence of death by gold has been found.

In 2013, The Geological Society published a collection of essays called A History of Geology and Medicine. One article, "Pharmaceutical use of gold from antiquity to the seventeenth century," points out that there is at least one modern medicine that includes gold: Myocrisin, an injectable used for rheumatoid arthritis.

Back to the subject of liquid gold: who figured out that hydrochloric and nitric could dissolve gold? That was a 9th century writer who produced the oldest known classification system of chemical substances. His name was Jabir ibn Hayyan, and you'll learn more about him next time.

Averroes

(Note: Most of this is from the previous post "The Commentator" on 11 December 2012)

Averroes (1126-1198) was born in Córdoba into a family of distinguished jurists and scholars at a time when Islamic culture was flourishing in Spain. He probably would have spent his life as a judge if not for his mentor and friend, the physician Abu Bakr ibn Tufayl, who told him that he should write commentaries on the works of Aristotle. The problem seen by ibn Tufayl was that Aristotle was too obscure either because of the ambiguity of his own writing or the shortcomings of his translators.

Averroes, whose real name was ʾAbū al-Walīd Muḥammad bin ʾAḥmad bin Rušd, embraced the task so thoroughly that, to the West, he became known as "The Commentator." His scholarship was embraced across cultures: Jacob Anatoli translated Averroes' Commentaries into Hebrew. Anatoli's colleague and friend Michael Scot translated some directly into Latin.

He analyzed and promoted most of Aristotle (and Plato's Republic) to the known world, as well as writing dozens of books of his own. So far as we know, he did not have access to original texts—there is no evidence that he knew Greek—and so his commentaries are based on Arabic translations of Aristotle.

He was a rationalist, he asserted that philosophy and religion were not in conflict because they taught about the same things. Common people needed religion and faith to understand what the intellectual could understand through reason and logic. He felt proper understanding of the Koran required analytical thinking.

Unfortunately for him, his rationalist views often got him into trouble when they came up against Islamic theology (which he had studied extensively). He was, in fact, banished by a caliph to whom he had been the personal physician, because some side remarks in Averroes' writing (such as "that Venus is one of the gods") struck the caliph as blasphemous. Fortunately, Averroes was allowed to return home prior to his death.

We've looked at a few different philosophers. Next I want to talk about a particular medieval school of philosophy: scholasticism.

Scholar of the Supernatural

[I am on a brief vacation, so here is a post from the past. This post first appeared 23 August 2012.]

In Dante's Inferno, the eighth circle is reserved for sorcerers, astrologers, and false prophets. There the narrator sees Michael Scot. You might think, if someone were so well-known after his death, that we would know more about him. Well, we know a little, but we have some cool stories.

Michael Scot, depicted here tearing up the Scriptures.*

Michael Scot was no doubt born in Scotland, although other locations (like Salerno and Toldeo) have tried to claim him. Dates of 1175-c.1232 seem to work for what little we know of his life. We know that Pope Honorius wrote to Stephen Langton on 16 January 1223, urging him to grant Scot a religious position, and that Honorius himself nominated Scot for Archbishop of Cashel. If Scot was educated sufficiently to be offered these positions, he would not have lived until 1290, which is the date Sir Walter Scott offers for his death. (Scott was confusing Scot with a Sir Michael Scot who lived later.)

Scot turned down the position in Cashel; it looks like he did hold benefices in Italy, however, spending time in Bologna and Palermo before going to Toledo in Spain. It was probably in Spain that he learned Arabic, which helped get him invited to the court of Holy Roman Emperor Frederick II. Besides translating texts for Frederick, he was a court astrologer, saying of the work:

Every astrologer is worthy of praise and honor, since by such a doctrine as astrology he probably knows many secrets of God, and things which few know.

This was not likely to endear him to the Roman Catholic Church.

Although he was known in his lifetime as a brilliant Aristotelian scholar, and Fibonacci's Liber Abaci was dedicated to him, his books on alchemy and astrology and the occult sciences earned him a reputation for magic. A Bronze Age circle of stones in northwest England called "Long Meg and Her Daughters" was supposedly a coven of witches turned to stone by Scot. Other stories have him hosting feasts served by invisible spirits. Boccaccio refers to him in the Decameron as a magician. It is also told (long after the fact) that he predicted he would die from a small stone falling on his head from a great height. He always wore an iron cap to prevent it, but he removed the cap when entering a church one day (more not to stand out than for reverence of God, we are told), and a small stone of the size he predicted fell on his head. He picked up the stone, recognized that his prophecy was coming true, put his affairs in order, and died of the head wound shortly after! His reputation (helped by the dearth of facts) has made him a prime subject for fiction right up to the present day.

The Commentator

Statue commemorating Averroes in Córdoba

Averroes (1126-1198) was born in Córdoba into a family of distinguished jurists and scholars at a time when Islamic culture was flourishing in Spain. He probably would have spent his life as a judge if not for his mentor and friend, the physician Abu Bakr ibn Tufayl, who told him that he should write commentaries on the works of Aristotle. The problem seen by ibn Tufayl was that Aristotle was too obscure either because of the ambiguity of his own writing or the shortcomings of his translators.

Averroes, whose real name was ʾAbū al-Walīd Muḥammad bin ʾAḥmad bin Rušd, embraced the task so thoroughly that, to the West, he became known as "The Commentator." His scholarship was embraced across cultures: Jacob Anatoli translated Averroes' Commentaries into Hebrew. Anatoli's colleague and friend Michael Scot translated some directly into Latin.

He analyzed and promoted most of Aristotle (and Plato's Republic) to the known world, as well as writing dozens of books of his own. So far as we know, he did not have access to original texts—there is no evidence that he knew Greek—and so his commentaries are based on Arabic translations of Aristotle.

Unfortunately for him, his rationalist views often got him into trouble when they came up against Islamic theology (which he had studied extensively). He was, in fact, banished by a caliph to whom he had been the personal physician, because some side remarks in Averroes' writing (such as "that Venus is one of the gods") struck the caliph as blasphemous. Fortunately, Averroes was allowed to return home prior to his death.

One of his most radical ideas, based on Aristotle, was that there were multiple intellects, but only one shared soul for all of mankind. To explain that raises more questions, however, unless first we look at a debate I have been putting off for months. Tomorrow, therefore, we will (finally) discuss Nominalism vs. Realism.

Jacob Anatoli

Daily Medieval has frequently mentioned the importance of Arabic texts in the transmission of knowledge to Western Europe. Arabic, however, was not a commonly known language, and Arabs did not have a strong presence in Western Europe. Arabic culture often brushed up against Latin culture in the southern Mediterranean, as mentioned Salerno, or when a scholar such as Michael Scot made it a point to learn Arabic. Scot probably had help in the form of Jacob Anatoli.

Jacob ben Abba Mari ben Simson Anatoli (c.1194-1256) grew up in southern France, and gained such a reputation for scholarship that he was invited to Naples by Frederick II, who gathered several other academics to his court, such as Scot and Fibonacci. Anatoli became known for his translations of Arabic texts into Hebrew, and he very likely aided Michael Scot in his Arabic translations. Roger Bacon explains that Scot was aided by a Jew named Andreas, and some scholars believe "Andreas" to be a misunderstanding of "Anatoli."

Of his non-translations, the greatest work is the Malmad ha-Talmidim (the title is a pun, being interpreted either "Teacher of the Students" or "Goad to the Students"). The Malmad shows a wide range of knowledge, incorporating the Old Testament and Jewish commentators, but also the New Testament, Aristotle, Plato, and Averroes. His egalitarian approach to Christian and Muslim matters was refreshing, but Judaism still had special status; he wrote "the Greeks had chosen wisdom as their pursuit; the Romans, power; and the Jews, religiousness." He tells us that a non-Jew who seeks religious Truth should be respected by Judaism and not mocked.

Anatoli extended this intellectual courtesy to Frederick II, incorporating remarks by the emperor in his works. He also mentions a Christian whom Anatoli considers a second master (after Anatoli's own mentor, Samuel ibn Tibbon); this "master" has been equated to Michael Scot.

As for his Arabic translations, Anatoli's crucial contribution was exposing the West to the work of Averroes, one of two Arab scholars (the other was the medical expert Avicenna) whose work is considered fundamental to the Middle Ages.We'll look at Averroes tomorrow.

The Chronicle of Melrose

Melrose Abbey, on the Scottish border, mentioned in connection with St. Cuthbert, is historically significant for other reasons. Many Scottish kings are buried there, and a stone coffin found in 1812 under an aisle in the south of the abbey was speculated to be that of the "wizard" Michael Scot. And although Robert Bruce was said to have been buried in Dunfermline Abbey, his embalmed heart was supposedly buried on the grounds of Melrose, encased in lead.

The Abbey had a checkered history. Long after Cuthbert's time, it was damaged in 839. King David I of Scotland (1084-1153) wanted it rebuilt, but the Cistercians who would populate it picked a different site with more fertile land for farming. It was rebuilt and its church dedicated in 1146. In 1322, much of the Abbey was destroyed by Edward II of England (1284-1327). It was rebuilt by Robert the Bruce. In 1385 it was burned by the forces of Richard II of England (although he did grant them some money in 1389 in compensation). Rebuilding began again, but stalled. At the beginning of the 16th century, it still wasn't complete. That was probably just as well, since in 1544 the Abbey was again damaged by English forces attempting to force the marriage between Mary Queen of Scots and the son of Henry VIII. And of course, Oliver Cromwell felt the need to bombard it with cannon fire in the 1640s, even though it hadn't held a monk since 1590.

As well as majestic ruins and burial legends (and the ghostly monks said to walk the grounds), Melrose left us something else. Not directly though: it was found in the Cotton Library as Faustina B.x, and investigation traced its origin to Melrose.

Page for 1246, 1247, 1248

The Chronicle of Melrose has two sections. The first, covering from 735 until 1140 (the new founding), is a summary of the Anglo-Saxon Chronicle and other works, including that of Roger of Hoveden. It adds nothing new to our knowledge. The second section, from 1140 until 1270, is unique. The handwriting changes over time, suggesting that it was added to contemporaneously by eyewitnesses, rather than compiled all at once like the first section.

As a singular Scottish viewpoint on events, it is invaluable. A 1263 battle between Norway and Scotland is part of a saga written by Icelandic historian Sturla Thordarson (1218-1284). The Chronicle of Melrose offers a second viewpoint from the Scottish side, confirming the fact of the conflict—if not precisely the same details. A series of mis-steps caused the Norwegian forces to cede valuable ground and, in deteriorating weather, they retreated. The monks' Chronicle puts it a little differently:

A.D.1263.  ... it was not man's power which drove him away, but the power of God which crushed his ships, and sent a pestilence among his troops. Such of them as mustered to engage on the third day after the feast of Michaelmas, God defeated and slew by means of the foot-men of the country. Thus they were compelled to carry off their wounded and slain to their ships, and to return home in more disgraceful plight than they had left it.

The Chronicle also gives us a list of deaths and promotions of abbots and lords and high-ranking laymen, radical weather and the appearance of comets, the ups and downs of political figures in Scotland and the northern English shires, and the earliest list extant of Scottish kings. It's another valuable tool in piecing together the complex history of the Middle Ages.

Frederick II

Frederick II of Sicily (1194-1250) has crossed the path of this blog more than once, but has not yet been featured.

He declared the Edict of Salerno, separating physicians and pharmacists.
Frederick was interested in math and science, and was friendly to and supportive of Fibonacci.
He promised to go on the Fifth Crusade, mentioned here, but never participated; he was blamed for its failures by Christians all over Europe as well as Pope Honorius III (who had been Frederick's tutor while young).

From the time he was declared Holy Roman Emperor in 1220 until his death 30 years later, he was a tremendous influence on science and culture, but a difficulty for popes and religion—odd, considering he willingly took the title Holy Roman Emperor. Although Pope Innocent III was his guardian growing up, Frederick often said blasphemous things, supposedly mocking Moses and Jesus and Mohammed for being frauds. His public attitude toward religion was unusual for his era and position, and Dante's Inferno places him in the circle of hell reserved for heretics.

He was, however, also possessed of a rationalism that was unusual for his era. He hired Arabs/Muslims as soldiers and personal guards; he hired Jewish scholars to be at his court. He pointed out the unfairness of trials by ordeal, because the stronger man would always win regardless of guilt or innocence. He hired the mathematician and scholar Michael Scot (of whom Honorius III thought very highly) to, among other things, make new translations of Aristotle and Arabian works into Latin. Michael Scot's translation of Aristotle was done with the help of Hermannus Alemannus ("Herman the German").

He had three wives and several mistresses. His third wife was Isabella of England, the daughter of King John Lackland. It was a political marriage, taken on because marrying an English princess would make his political opponents lose support from England. Once Isabella arrived in Sicily, she was sent to live in seclusion in Padua with only two of her English retainers.

Although Frederick had a profound and positive impact on laws and science, his personal manner made him many enemies and detractors. The Hohenstaufen lineage, which had included Frederick Barbarossa, lost power after Frederick II's death.
