"I feel like I'm wrecking this place somehow just by being here," Feyik murmured in wonder as he and Iqal stared up at the old bookcases looming all around them.
Blushing a little, Iqal wove one hand into his hair and hunched his shoulders. "Tell me about it," he muttered, letting his eyes wander from shelf to shelf. The room itself was not the largest they'd visited during the trip - a fair-sized sitting room, but lined with old shelves, clearly painstakingly maintained over the years and bedecked with heavy tomes and codexes, some of them seeming to be older than time itself.
Perhaps less inspiring, but no less imposing, were the velvet-trimmed length of cord politely separating the students and their teacher from the shelves, as well as the signs exhorting them not to touch anything.
As the students browsed through the museum, Iqal found his gaze drifting towards his professor, only to start as he realized he wasn't the only one looking. Dr. Mirza chuckled simply and shook his head.
"You're hardly tainting the place," the professor assured. "You're in a house of learning, after all. Ibn al-Layth was probably used to having people coming to him to learn."
"Ah... yeah, maybe," Iqal conceded with a sheepish smile, gaze drifting through the room, towards a couple of roped-off chairs and an elegant table set nearby. Recreations, of course - the house had changed hands too many times over the years for things like that to survive.
"I wonder how they knew what kind of chair Ibn al-Layth was sitting in," the young man murmured with quiet wonder.
"They don't," conceded Dr. Mirza as he moved to stand beside the two students. "Part of studying history is a process of deductive reasoning and educated inference. The same goes for naturalism,[1] when you get right down to it. We may never objectively know what kind of chair Ibn al-Layth owned. But we can infer it based on what we do know about Andalusi furnishings and the means of the scholarly class during this period."
"Hold on," Feyik put in with a blink. "Since when do we know what furniture from a thousand years ago looked like?"
Dr. Mirza smiled pensively. "Surprisingly there have been chairs from centuries ago found. Things like tables. Stools. Other furnishings. They constructed things in those days as if you were investing in something truly luxurious. In fact, this period is something of the start of an age of inspiration."
Furrowing his brows, Iqal squinted at the chair for a moment, letting hiseyes travel the lines of it - bronze framing, elegant cushions in complex geometric patterns, workmanship like someone had slaved over it for decades just to get it right. It was the sort of thing you would never find at a furnisher's store these days.
"Why were people so inspired?" he asked. "I mean, to make... chairs. And to be Ibn al-Layth."
"Well," Dr. Mirza said with a tilt of his head, folding his arms. "We talk about the Rule of the Slaves sometimes just based on politics. But it was also a time when a lot of new avenues in high society were opening for indigenous Muslims in this part of the world. A lot more creative people had a lot more opportunities in those days. Skill and imagination were a lot more important."
Iqal nodded, taking stock of the chair again, then turning his gaze back to the books. Not for the first time, he wondered if someone of his bloodline had once wrought chairs like that, or written tomes like those, or sat in a library just like this one.

Excerpt: Falcons of Early Naturalism - Abdullah Ghazi, Naturalist Documentary Press, AD 1964
Ibn al-Layth (Abu' l-Hasan Aamir ibn Tariq ibn al-Layth)
AD 1033 (Tlemcen, Maghrib) --> AD 1114 (Al-Jazirah, Andalusiyya)
Of the great early naturalists associated with the cultural and intellectual flowering which took place during the period known as the Rule of the Slaves, Ibn al-Layth is considered among the most eminent. His contributions to naturalism came to exercise a great impact on the daily lives of Andalusians, and later on the broader Muslim world. The advances in medicine and personal cleanliness he pioneered made daily life better and healthier, once fully embraced.
Born in Maghrib during the reign of al-Muntasir, the son of a well-respected Berber family with a history of public service, Ibn al-Layth fled his hometown of Tlemcen in the 1060s during the early days of the rise of the Al-Mutahirin movement. He landed in the port of Al-Jazirah but soon traveled north to Qurtubah, where he pursued advanced studies in philosophy, theology and in particular the nature of medicine.[2] However, while he grew up in an atmosphere in which rigorist interpretations of the Quran ran rife, with the ultra-intense fixations of the Purists firmly in the background of his learning, Ibn al-Layth seems to have been nothing less than a skeptic's skeptic, approaching learning through a thoroughly non-mystical mindset.
Perhaps the most remarkable trait of Ibn al-Layth as a thinker was his conceit that logic and faith did not contradict each other. An admirer of classical learners, particularly the Greeks, he seems to have held a hope of demonstrating the greatness of Islam by proving the rightness of God and His works not only through faith, but through empirical logic utterly undeniable to any reasonable audience. In his early writings, Ibn al-Layth posits that there are two paths to wisdom: Quranic wisdom on one hand, and logic on the other. Critical analysis of Ibn al-Layth's writings strongly suggest that he was intimately familiar with the works of Aristotle; in particular, his short treatise
Concerning Reason and the Revealed, he seems to strike a few Aristotelian notes, ultimately drawing the conclusion that logic is a parallel course in interpreting the world - in particular, he suggests that while God is the ultimate cause of all things, creation comes more as a set of divine laws than as direct interventions, and logic can be used to understand those laws.
While Ibn al-Layth is known more for his contributions to medical naturalism than Islamic logic, his thinking nevertheless represents an early example of the diverge of Islam in Saqlabid al-Andalus from that in Arabia and Mesopotamia. In the east, Arab and Persian intellectuals had begun to adopt the teachings of Abu al-Hasan al-Ash'ari in earnest; intellectuals such as Ibn al-Layth would begin to move in the opposite direction as more and more Muslim conversos began to move into the ranks of upper-class thinkers, bringing with them new takes on Islamic theology, some of them coloured by their negative experiences with rigorist sects.
The primary contribution of Ibn al-Layth comes from where his life experiences drew his study of medicine. Driven out of his home as he was by the blandishments of the Al-Mutahirin, Ibn al-Layth harboured more than a few doubts about the group's extreme theology, which emphasized a radical form of
taharah - the Al-Mutahirin were known for their obsession with ritual purity, in particular extending their beliefs to a general conceit that non-Muslims, Alids[4] and even those they deemed to be insufficiently zealous in their devotion to God should be considered unclean and removed from the presence of the believers. This obsession with their own purity dictated the behaviour of the Al-Mutahirin upper class: They zealously segregated themselves from their subjects and heavily robed themselves when leaving their dwellings, and they tended to drive Christians, Jews and Alids out of cities and towns they captured, believing that all but the most deeply heartfelt conversion to Islam would leave the converso with an indelible taint upon their faith. The fixation led them as well towards extreme views on purity of belief; the group tended towards rather casually labeling any notable sinner a
kafir.
Broadly speaking, the views of the Al-Mutahirin on purity stemmed from their incredibly rigid form of jurisprudence. The movement's leaders rejected
qiyas as a path to enlightenment and considered anything beyond the
Quran and the musings of the first generation of Muslims to be invalid and heretical as a source of knowledge. The sect considered innovation and heresy to be unforgivable sins and anyone who participated in them to be actively contributing to the destruction of Islam, and their jurisprudence was rooted in the ideal of purifying the faith of innovation and restoring it to the original, pure form of belief as embodied by the Prophet (PBUH).
For his part, Ibn al-Layth viewed the Al-Mutahirin's lead preacher, Badis ibn Yusuf, as cut from the same cloth as the
Khawarij.[5] It is in the context of his contempt for Badis and his take on faith that Ibn al-Layth turned his medical knowledge to the task of testing Badis's premises concerning purification. The result of this work was his most well-known treatise,
The Methods of Proof Concerning the Cleanliness of the Spirit and the Body. In some printings it is known by the more dramatic title
The Filth of the Purists.
Ibn al-Layth's treatise is effectively twofold. The first and less naturalistically compelling segment of the document is a rigorous refutation of Badis based on Ibn al-Layth's formidable knowledge of
fiqh, in which he comes to the conclusion that Badis and his followers are hypocrites acting upon a
bid'ah[6] and damaging Islam even as they profess to be purifying it.
The second component of
Methods of Proof is a purely medical document in which Ibn al-Layth details an extensive study of cleanliness, filth and its relation to the spread of sickness. In particular he conducted an analysis of the illnesses confronting common Andalusians at the
Bimaristan of Qurtubah versus those facing the people he met at court in Qurtubah, who were less likely to come into contact with filth on a regular basis.
Ibn al-Layth's recommendations boil down to the earliest known treatise on sanitation and personal hygiene. Building on existing
hadith which emphasize not bringing sick or unclean animals into the presence of other animals, Ibn al-Layth issues a series of recommendations concerning the proper disposal of human and animal waste and on supplementary body hygiene, expanding on various elements already enshrined in
fiqh. In particular he expands on the types of water which may be considered impure by analyzing medical factors alongside spiritual ones, specifically excluding any water which has been in the presence of an unclean animal or a sick person, and makes recommendations around frequency of full bathing, complementary to jurisprudence concerning ablution. The document goes on to emphasize the importance of cleanliness, but suggests that purifying to excess - as in the case of Badis and his followers - will unbalance the body's humours and weaken the constitution.
Methods of Proof is considered one of the earliest medical texts clearly emphasizing the importance of hygiene, sanitation and cleanliness to the medical health of a community. The text seems to have circulated to some extent in Ibn al-Layth's lifetime, but certainly serves as an example of the key advantages in sanitation and personal cleanliness Andalusians enjoyed over most of Europe at the time, as well as an emphasis on the importance of a high standard of care for the body. It is also one of the first documents to hint at the role played in human and animal byproducts in the spread of epidemics.
While Ibn al-Layth's work would not immediately lead to improvements in civic sanitation, he also penned a series of treatises concerning other medical conditions. The most notable is his early identification of food debris as a cause of tooth decay, though he considered such food waste not so much the direct cause as a factor which allowed toothworms to proliferate. His
Methods of Proof for the Care of the Mouth became the guiding text on ostial care[7] in much of the Muslim world, becoming widely referred to within his lifetime in Andalusia. In another text, he produced a startlingly complete anatomical study of the human skull.
Ibn al-Layth's work took some time to proliferate outside of Andalusia and the western Maghreb, encountering in particular the tendency of the Al-Mutahirins to consider him a Mu'tazilite and a
kafir. His texts proliferated primarily through the
Bimaristan established by Hisham II about a century before and circulated from there through the travels of visiting scholars and physicians.
Late in life, Ibn al-Layth served as a court physician at the expanded Alcazar in Qurtubah, but eventually was granted the right to retire, well after the rule of Wahb and Abdullah II. He returned to the port of Al-Jazirah and took up residence just outside the city, where he died a peaceful death while reading in his library. Today, the home thought to have once belonged to him is preserved as the Ibn al-Layth House National Museum and Library.
