There has been a bit of a gap in posts, but I had been doing a series of post inspired by Ethan Masood‘s book Science & Islam. I’m coming towards the final topics now, but certainly not to the least of them. Medicine could perhaps be picked out as one of the greatest achievements of Islamic science. While some parts of science could come into conflict with religion, the treatment of the sick had a pretty easy start in the Islamic world – Muhammad himself said to make use of the best methods out there. This was seized on with some enthusiasm and, while it was far from the first culture to have hospitals and charitable institutions, advanced hospitals were common.
As with most Islamic scholarship, the roots of the subject came from ancient Greece. Even the terms Chemisty and Alchemy are derived from ancient greek terms. At this early stage of Chemistry, there is still a huge mixture between what would correspond to real science (Chemistry) and what would correspond to utter nonsense (Alchemy) – similar to Astronomy and Astrology but possibly harder to discern. Despite the subject not yet being fully refined, there was still the beginnings of skepticism and a more structured scientific method. In practical terms there were great developments in equipment and results – particularly in the field of medicine. To include the huge amount of discoveries, I would basically have to write a list of names and dates. Therefore for the sake of readability I’m going to focus on just a few of the big names.
Geber and Pseudo-Geber
The source of much of this is Jabir Ibn Hayyan, otherwise known as Geber, a scholar from Persia in the 8th century. His name was so bound up with the subject of chemistry that there is even a so-called “Pseudo-Geber” who put out his own work under the name of the earlier scholar as “translations”. This, and the usual mysteriousness associated with the profession of Alchemy, can make it difficult to pin down the genuine works of Geber. Regardless of this, both Geber and Psuedo-Geber did much for the science.
As you may have noticed from this blog, I listen to a decent amount of podcasts. One of my favourites is Robin Pierson’s History of Byzantium. I was pleased to find that they recently had on a special guest, one of my favourite history writers, Tom Holland. As the podcast had reached a handy stopping point just after Islam had exploded onto the world stage, it was a perfect chance to begin trying to shed some light on the origins and early stages of the religion and the arab invasion. The author of a recent book on the subject aimed at a popular audience, Holland was an ideal choice to start things off.
A few weeks ago I posted a review of the book Science & Islam by Ethan Masood, a tie in with a BBC series from about five years ago. I felt that the book was a bit of a let down, but loved the topic and wanted to read more on it. As a follow up I then wrote a post giving a bit more detail on the Islamic contributions to Mathematics. I wouldn’t pretend that I’m a better writer than Masood, but I wanted to focus a bit more on some of the techniques and details of the work than he did. I do have a scientific background, but I don’t want to make this into a science blog so I’m attempted to strike a bit of an awkward line between the history and the science. With that introduction/disclaimer out of the way – here’s a short summary of the Islamic world’s contribution to Astronomy.
Looking at it now, Mathematics may be the headline grabbing topic for the Islamic golden age but Astronomy (and its unfortunate and misguided relative Astrology) were at least as important. Not only did they provide the motivation for a lot of the work in mathematics and physics, but they also did a lot of very underrated work in moving the topic forward from its ancient roots towards the early heliocentric model of Copernicus. Islamic scholars invented technologies like the astrolabe, published tables of data that later scientists would draw on, and worked out a lot of the mathematical difficulties for the later models. Unfortunately, the political and educational system in the Islamic world meant that they weren’t fully able to capitalize on this; the wonderful observatories were only ever short term institutions and the whole thing stagnated around the turn of the sixteenth century.
Most people will probably know that the mathematicians of the Islamic world have played a big part in mathematics as we know it – terms like “algebra” and “algorithm” is a bit of a give away, and the invention of zero is a common bit of trivia. Not as many people may be familiar with the characters and setting behind these inventions or the full extent of their mathematical achievements. These weren’t just abstract creations either, they often had practical uses for both everyday life and for other academic arts. This post is a bit of a deviation from a book (Science & Islam by Ethan Masood) I reviewed in a recent post – I’ve given a bit of a general run through of the general history there if you want to check it out (please do, views are always nice to have), but I’ve tried to keep this post relatively self contained.
Why did they study mathematics? Well, much like anyone else it was a mixture of the practical and the academic. Some of these scientists and philosophers would investigate more and more complicated work for its own sake, but there were also more down to earth reasons. Al-Khwarizmi’s work on algebra was explained as a way to speed up the complicated process of Islamic inheritance, and work on trigonometry was needed for new techniques in navigation and astronomy (okay, maybe that last one is a bit less down to earth). The work was, as with more scientific work, generally funded by a patron or ruler.
I recently read Science & Islam by Ehsan Masood, designed to accompany a BBC television series, and decided to put out a post on it. To spoil things up front, I found the book disappointing but the topic fascinating so I began writing a huge essay on it. So huge in fact that I’ve decided to split it into a number of posts. This first one will give a general history and my thoughts on the book itself, and it should be followed by a post or two on the science behind all this (something that I think the book struggled to deal with as much as I would have liked).
The Rise of Islam
When the Arab armies came storming out of the desert into the tired Byzantine and Persian Empires, their initially success was astounding. They soon found themselves in control of a vast empire containing a mix of religions and peoples in which arabs and Islam were a minority. This shift from military expansion to administration provided a set of challenges for the Caliphate to deal with – providing food for the population, minting coins, providing a central administration and building new cities and buildings. This began a boom in science and technology that would last for centuries, but it did not start from scratch – those christians, jews and zoroastrians that had populated the land before would lend their talents to this and techniques would be brought in and translated from outside the reaches of the empire. The universal adoption of the arabic language helped this process, providing easy communication between scholars from distant lands.
