Was Islam really responsible for the Italian Renaissance?

Japan is well known for being a highly industrialised and technologically sophisticated East Asian country; if one was to say that Japan owed its technology to the Greco-Roman influence of Europe this would miss out the large contribution that modern Europe has made to both science and technology; likewise with Islam in relation to Europe.

Karen Glasner wrote the following in her introduction to Averroes Physics:

The great 12th C Muslim philosopher Abu al-Walid Muhammed Ibn Rushd, known in Latin as Averroes, has the reputation of having been Aristotles most faithful interpreter and has been referred to as 'the Commentator'. He was viewed as being a bold philosopher in teaching Aristotles philosophy in Islamic society, but not so much as an original thinker in the Aristotelian tradition. He was usually regarded as a competent, didactic exegete rather than an original creative thinker, and was sometimes depicted as a 'slavish follower' of Aristotle. At least as far his physics is concerned this picture is far from true ... [he played] a major role in the history of atomism.

She goes on to say

Since Duhem, historians of science have realised that the new science of the 16th & 17th C owes more to medieval Scholastic thought than earlier generations of scholars had acknowledged. Aristotelianism was still a major frame of reference well into the 17th C.

And also

Annaliese Maier has shown the significance of scholastic theories of minima naturalia and forma fluens - that included some 'mildly atomistic' elements - for early modern thought on matter and motion. The contribution of Muslim philosophy, however, has not yet been duly acknowledged.

and she then adds:

according to the commonly accepted narrative, for example, the theory of minima naturalia was developed by Scholastic scholars from a few preliminary remarks from Aristotle. I will show that the theories of minima naturalia and of motion as forma fluens had been crafted by Averroes into a systematic, thoughtfully elaborated new physics. He developed these theories further than his predecessors did, and further than many of his followers were to do later.

To place these comments by Glasner into context one should recall Feynmans advice in the introduction to his Lectures in Physics, where he said if he had to encapsulate for future generations the whole of physical science in one sentence he would say 'everything is made of atoms'.

Also, Glasner points out the role of the commentary as a genre as to why Avveroes physics as a contribution to physics per se has been overlooked; I'd also point out along with Edward Said the role of the Orient as the playing the role of the Other in European thinking and such an Other could not be, even indirectly, responsible for the content that inspired Europes fascination for the natural philosophy, aka the physical sciences.

The Arabs, specifically, the Moors, had a significant impact on the Northern Italian Renaissance alongside the Greco-Byzantines-(as I had discussed in a previous posting).

During my pre-collegiate years, when I was taught about the Middle Ages, specifically, "The Dark Ages"-(476 AD/CE-1050 AD/CE), I was taught that continental Europe, more specifically, lands and countries to the NORTH AND WEST of Rome, were intellectually stagnant and primitive.....essentially, a "Dark Age", bereft of creative light ingenuity and sophistication. (The phrase, "Dark Ages", was actually coined by the Northern Italian Renaissance Poet Petrarch).

Even though this was widely considered to be an accurate description of Northern and Western Europe 1000-1500 years ago, it was, as you can see, geographically and demographically limited in its description. It failed to contrast the so-called "Dark Ages" of Northern and Western Europe with the culturally advanced civilizations of Southern Europe........specifically, the Greco-Byzantine Christian civilization based in Constantinople-(present-day Istanbul), as well as greater Byzantine Greece and in particular, Muslim Spain, specifically, the cities of Toledo and Cordoba-(The Capital of the Medieval Iberian Caliphate).

The Islamic world during the Middle Ages had thriving intellectual and academic cities, such as Cairo, Baghdad-(yes.......the same beleaguered city you hear about in the news), Bukhara, Fez, Toledo and Cordoba. Its intellectual and academic influence was multi-continental and lasted throughout much of the Middle Ages-(including the so-called, "Dark Ages"). Arguably, the most advanced centers of Islamic arts, letters, sciences and Classical scholarship, were the Castilian city of Toledo and particularly, the Andalusian city of Cordoba.

The city of Cordoba, like its Medieval counterpart, Constantinople, was a massive Metropolis with hundreds of thousands of residents-(including, Jewish and Christian residents.......though admittedly, with less religious and legal equality). The city was a major urban Capital with great wealth; it had a Palace, splendid buildings, its famed Mezquitta/Mosque, a Library, as well as a University.......(and that's just a limited description). Though it was the vibrant intellectual life of the city which made it distinguishable from the rest of continental Europe-(Constantinople, as well as Charlemagne's capital Aachen in Northwest Germany, being the exceptions). Ancient Greek scientific, medical, mathematical and especially, philosophical/metaphysical works, were translated into Arabic-(with great assistance from Jewish Translators and Scribes). The writings of Plato, Aristotle-(in particular), Euclid, Archimedes, Hippocrates-(just to name a few), were translated into Arabic throughout Medieval Muslim Spain, though its Epicenter, was Cordoba and its most learned resident, was Ibn-Rushd/Averroes.

Although Aristotle's writings were well preserved and commented on by the Greco-Byzantines, it was actually Averroes who rejuvenated the centuries old Greek Philosopher......so much so, that the study of Averroes' Aristotelian commentaries and writings would later be described by the West as, "Averroeism".

The writings of Averroes, as well as the sizable collection of Arabic translations of Ancient Greek texts from Medieval Muslim Spain, would actually have a profound impact on The European Late Middle Ages-(1050 AD/CE-1400 AD/CE), which of course precedes, the Northern Italian Renaissance. These Ancient Greek "classics", were translated into Latin from either Medieval Byzantine Greek copies from Constantinople or from Medieval Muslim Arabic copies from Toledo and particularly, Cordoba.

Galileo-(the Great intellectual Titan of the Northern Italian Renaissance), studied Italian-(and possibly Latin) copies of Aristotle, Archimedes, as well as the Ancient Greco-Alexandrian Scientists and Mathematicians. However, there is a very good chance, that those Italian-(and/or Latin) copies may have been Medieval Greek or in all likelihood, Arabic translations from Toledo or Cordoba.
Galileo's school, The University of Padua in the Veneto-(Northeast Italy), had, during his time, the most prestigious Medical School in Europe-(and perhaps the world). The process of Surgery and dissection were taught at The University of Padua; though such a supposedly novel process and approach was directly influenced and preceded by the earlier writings of various Medieval Arab Physicians. Galileo's famed telescope could not have existed without the early pioneering work of Medieval Arab Opticians and their research into the anatomy of the eye, as well as the Science of Lens crafting.

The early Modern Universities and Libraries of Europe-(which include, The University of Padua), were certainly influenced by the older Medieval European Universities. However, the Medieval European Universities and Libraries were preceded by the earlier Medieval Universities and Libraries of Constantinople, Cordoba and Fez-(which exists to this day).

One can find examples of Medieval Arab Andalusian architectural influence in some of the public buildings, stucco and pastel designs, narrowly paved lanes and yes even some religious buildings throughout Tuscany and the Veneto-(the Epicenters of the Northern Italian Renaissance). Of course many of these above mentioned examples were deeply rooted in Roman civil architecture and engineering. However, it was the Muslim Moors who, (along with the Greco-Byzantines from Constantinople), picked up where the Romans ended and in turn, helped to shape the memorable and long lasting brilliance, ingenuity and aesthetic beauty..........of The Northern Italian Renaissance.

Question:
Was Islam really responsible for the Italian Renaissance?

Short Answer:
Yes a major factor would be hard to dispute. The word Renaissance means rediscovery and where does one think Europeans immeriging from what is often referred to as the dark ages, rediscovered architecture, astronomy, medicine, philosophy, science(botany, biology, physics, chemistry) and mathematics (algebra, geometry) from? In the mid 1400's Christian Europe had spent several centuries identifying and systematically destroying the pagan knowledge of Rome and Greece as heretical. The Islamic world was a repository for this knowledge which Europeans drew upon. More than that. To take just mathematics into focus. What would modern math be like today without our Arabic numbering system? The Zero, Algebra, Average, Zenith, Nadr, Azimuth, Cipher and the concept of an Algorithm? All Islamic innovations. It's frankly impossible to image Calculus a more modern european invention without these earlier Islamic building blocks. Mathematics is a representative sampling of not only science but philosophy, architecture, engineering, astronomy, and medicine; all rooted in Greek and Roman scholarship but expanded upon and passed down to us from Islamic civilization.

Islam was the caretaker of ancient European learning and Western European Civilization as built on Greek, Roman, ideology is also built on Islamic contributions.

Detailed Answer:

The Moslem world was vastly more sophisticated than Europe in the early middle ages(commonly referred to as the dark ages of Europe). Contact with this advanced civilization had to inspire Europeans. Europeans first impressions of the Moslems came during the Spanish expansion and then from knights during the Crusades. Muslim cities during this period had streetlights, indoor plumbing for both drinking and waste water, Universities and Hospitals. Not only were these innovations unheard of in Christian Europe, but the scale of these services being provided to average citizens were beyond anything Europe was could entertain.

The Muslim world had built on and expanded the knowledge of Greece and Rome; Europe at the time, did not have access to much of Roman and Greek works and htus was unable to reproduce their achievements, much less expand upon them.

Plumbing

History of Water Supply and Sanitation
In the Abbasid Caliphate (8th-13th centuries), its capital city of Baghdad (Iraq) had 65,000 baths, along with a sewer system. Cities of the medieval Islamic world had water supply systems powered by hydraulic technology that supplied drinking water along with much greater quantities of water for ritual washing, mainly in mosques and hammams (baths). Bathing establishments in various cities were rated by Arabic writers in travel guides. Medieval Islamic cities such as Baghdad, Córdoba (Islamic Spain), Fez (Morocco) and Fustat (Egypt) also had sophisticated waste disposal and sewage systems with interconnected networks of sewers. The city of Fustat also had multi-storey tenement buildings (with up to six floors) with flush toilets, which were connected to a water supply system, and flues on each floor carrying waste to underground channels

Street Lights

Cordoba: A City of Light
Located in the Iberian Peninsula, Cordoba was one of the prominent centers of learning and culture in the enlightened Muslim world. While the rest of Europe was going through its dark ages, this was the most prosperous and sophisticated metropolis in the continent. It was the capital of Muslim Spain, spanning the region known today as Spain and Portugal, during 756 to 1031 C.E. and this was its most glorious period.
…
The streets were well paved and lighted, the lights being attached to the outer doors and corners of the houses – which, as al-Muqaddasi notes, had tiled roofs. Cordoba was abundantly supplied with running water, for the supply of which ‘Abd al-Rahman I had constructed an aqueduct.

Hospitals

The Islamic world in the Middle Ages - BBC
Throughout the Middle Ages, the Muslim world was more advanced and more civilised than Christian Western Europe, which learned a huge amount from its neighbour. Part of History The Middle Ages (12th to 15th century) …
The Islamic world housed some of the first and most advanced hospitals from the 8th century, notably in Baghdad and Cairo. Built in 805, the Baghdad hospital housed a medical school and a library. Unlike medieval Christian hospitals, its aim was to treat patients, not just to care for them.

Universities

From Jami'ah to University Multiculturalism and Christian-Muslim Dialogue
Some scholars such as Syed Farid Alatas have noted some parallels between Madrasahs and early European colleges and have thus inferred that the first universities in Europe were influenced by the Madrasahs in Islamic Spain and the Emirate of Sicily.

University of al-Qarawiyyin It is the oldest existing, continually operating higher educational institution in the world according to UNESCO and Guinness World Records and is occasionally referred to as the oldest university by scholars.

The word "Renaissance" literally means revival. It refers to a revival of science and learning in Europe. This was not the discovery of science, philosophy, architecture, math, astronomy, physics etc.. but was based on the reintroduction of learning from Greek and Roman times.

During the early middle ages in Europe Greek and Roman texts were considered heretical and burnt as pagan texts. Like at the Great Library at Alexandria.

The library of the Serapeum in Alexandria was trashed, burned and looted in 392, at the decree of Theophilus of Alexandria, who was ordered to do so by Theodosius I. Around the same time, Hypatia was murdered. One of the largest destructions of books occurred at the Library of Alexandria, traditionally held to be in 640

Burn, book, burn! Medieval book historian at The University of British Columbia, Vancouver.

The oldest surviving depiction of a book burning is early medieval: it is found in a law book from c. 825 (Pic 3). It shows a scene from some 500 years before. Shortly after the year 333 the Christian emperor Constantine declared his solution to the Arians, the followers of Arius, a Christian leader with heretical opinions. The solution was practical: burn the books in which Arian views are expressed - as well as their owners. The other two medieval images (Pics 2-3) also show a bonfire of heretical books. The top image, however, is something completely different. It does involve an old book, from the nineteenth

These texts survived in the Middle east where Muslim scholars added to the ancients understanding of medicine, architecture, science, mathematics, astronomy etc. The source of ancient European Knowledge was re-introduced to Europe through Islam which had preserved these pagan texts.

The Renaissance: The 'Rebirth' of Science & Culture
Classical Latin texts and Greek science and philosophy began to be revived on a larger scale, and early versions of universities were established. The Crusades played a role in ushering in the Renaissance, Philip Van Ness Myers wrote in "Medieval and Modern History." While crusading, Europeans encountered advanced Middle Eastern civilizations, which had made strides in many cultural fields. Islamic countries kept many classical Greek and Roman texts that had been lost in Europe, and they were reintroduced through returning crusaders.

From the Comments:

From: dROOOze You’re not addressing why it is not controversial in the early middle ages but it is controversial now.

I wasn't. The reason why it's not controversial to say Islam was responsible for the renaissance, is because we are not just talking about a religion in the middle ages when this occurred. Islam was an empire, the islamic empire which was a large sophisticated, unified civilization. We could not attribute such achievements today to a religion because today religions are not temporal powers, are not associated with an individual country much less a civilization. Religions are not nearly as uniformly influential even dominant as they were during the early middle ages. Today religions are not unified in leadership, doctrine or philosophy.

If we observe the act of book burning which occurs in some internal minor state or province and note the political person involved was say christian. Today that doesn't mean all christians agree those books should be burned. Even if a Pope said it today, it wouldn't mean all Catholics agreed with him. That wasn't the case in the early 1400's europe. When the Pope said burn pagan texts as heresy prior to the reformation he spoke for all of Western Europe/Christendom. Failure to comply meant you could face a similar fate. There was one church, one voice at the top, and that voice not only controlled church doctrine but also controlled powerful armies(directly and indirectly). The same was true of the Islamic Empire in the middle ages. And just as Christendom has been fractured by schisms, reformations and civil constraints placed upon religion by nationalists; Islam too has been decentralized today. Religions influence today just bares no resemblance to what it was in the early 1400's.

Yes assigning characteristics to a religion is fraught with controversy in the modern world. But in the early middle ages religion was synonymous with empires. Religious leaders were not relegated to the spiritual arena but dictated temporal policies which determined the path's of civilizations. In the west it was religious policy to burn heretical works and make scientific theory subservient to matters of faith. And in the middle east it was religious policy just as influential which chose not to take the same path.

Lets not get over zealous here in bashing Islam. Yes Islam played a great role in "our" renaissance.

Science survived due to the Islamic civilization. they invented our numeric system, the zero, decimal system.

They were the first who developed universities, in fact part of our university system is based on the Islamic system.

They conserved and further developed a lot of the science from ancient Greece an Rome, while we were busy burning books.

In the ninth century, the library of the monastery of St. Gall was the largest in Europe. It boasted 36 volumes. At the same time,the library of Cordoba, which was Muslim by that time, contained over 500,000!

Do not forget a big slice of the middle east was part of the Greece and Roman influence. Remember Cleopatra and Alexander the great? In fact our "Christian culture" was based in the middle east. The superhero of Christian Culture, Jesus himself came from Palestine.

Al Rhazes, a Muslim Doctor is considered to be the one who discovered the origin of smallpox and found that one could only acquire it once in his/hers life, thus showing the existence of the immune system and how it worked. He was an early proponent of experimental medicine and is considered the father of paediatrics, in addition to being a pioneer in neurosurgery and ophthalmology.

George Sarton, the father of the history of science, wrote:

"Rhazes was the greatest physician of Islam and the Medieval Ages."

I am not a scholar, but I think that, without Muslim research, development an science, our Renaissance never would have happened and we would have continued to burn books and convict heretics.

There is an element of truth to what your friend told you.

Civilization, so to speak, as manifested by the Italian Renaissance was sparked by a Spanish influence, however, the transfer was largely Christian in character. In other words, what kind of happened is that the Arabs invaded Spain and instituted a culture, then the Europeans defeated them, absorbed their cultural ideas and those ideas were transported to Italy where they contributed to the Renaissance.

For example, the mathematical science of "Algebra".

As one tiny example of this take Ruy Lopez (1530-1580), the greatest chess player in the world at one time. He was a Christian friar in Spain, but he learned chess out of the Arab tradition. Ruy Lopez's spiritual successor was Greco, the Calabresian master. So, even in chess, as in mathematics and chemistry, there is sort of a Spanish first, Italy afterwards progression.

The two claims are not incompatible. There was certainly a very large Islamic influence on the Italian Renaissance. Many classical texts are largely known to us through transmission via the Islamic world. For example, see Wikipedia's article on the Transmission of the Greek Classics. Interpretations of the classical texts, like those of Aristotle, were heavily influenced by Islamic thinkers such as Averroes (his latinzed name). According to Wiki:

Averroes had a greater impact on Christian Europe: he has been described as the "founding father of secular thought in Western Europe"and was known by the sobriquet the Commentator for his detailed emendations to Aristotle. Latin translations of Averroes's work led the way to the popularization of Aristotle.

Averroes spent most of his life in Spain, but his influence was felt in Italy, according to no less than Dante:

Averroes is named by Dante in The Divine Comedy along with the thinkers and creative minds of ancient Greece and Rome whose spirits dwell in "the place that favor owes to fame" in Limbo.

The Islamic world had also made original scientific advances, which influenced the Renaissance. But your question focuses on the Greco-Roman inheritance, so I'll leave those aside.

There's a definite influence of the Islamic world on the Italian Renaissance, but it's going too far to say that Islam "caused" or is "responsible" for it. Big events like the Renaissance have many, many causes.
