Catalog Entry: Manuscript of Al-Jazari’s Water-powered Elephant Clock
Al-Jazari was an acclaimed Muslim inventor and engineer who lived in the 12th century in modern day Iraq. He is considered one of the world’s greatest engineers, and is most well-known for his ingenious clock designs, specifically his famous elephant clock. The elephant clock manuscript is among the few that survived the many years. The illustration of the water-powered elephant clock was done on paper, using watercolor, ink, and gold, and was accompanied by detailed instructions for constructing the device, as well as in depth explanations regarding the functionality of each component. This invention, like many others in his book, demonstrates advanced knowledge of automata that inspired many engineers for years to come.
Al-Jazari is well known in the engineering world due to his book that was published in 1206, called “The Book of Knowledge of Ingenious Mechanical Devices.” The book was written because al-Jazari presented one of his inventions to the sultan, who recognized his ingenuity and requested that he produce a treatise of his inventions. This book is incredibly important in the history of Islamic culture as well as the engineering world. There is little documentation regarding ancient Islamic engineering, so al-Jazari’s detailed book has immense historical importance. The text that accompanies the illustrations is essential, as it describes exactly how the device should be built, and how the components of the device interact with each other. The text and illustrations go hand and hand and would not have the same impact if one didn’t have the other. The illustrations provide a clear idea on how the device should be assembled, and helps the reader conceptualize the building instructions. After the book was published, it spread the globe and inspired many inventions, as well as introduced unfamiliar mechanical devices to specifically early Europe.
The clocks in the manuscripts were more than just timepieces; they held significance related to their time period of creation. The elephant clock, for example, showcases al-Jazari’s extensive knowledge of mathematics and mechanics. Al-Jazari even invented his own measuring device that used advanced Euclidean and Archimedean geometry, presumed to be inspired by Greek mathematician Hero of Alexandria. What set him apart from the other inventors were his elaborate designs. Al-Jazari didn’t just recreate past clocks, he utilized the knowledge and ideas of earlier Muslim scientists and philosophers and built upon them. He used the work of his predecessors as inspiration and incorporated their ideas into his own inventions, helping to further the development of science and technology in the Islamic world. Al-Jazari not only improved upon past inventions, but also created his own. In fact, al-Jazari is credited with several important innovations, including the crank-connecting rod system, which was used to power a variety of machines and devices, including water pumps and his famous water clocks. When people read the details on how said pumps functioned, it helped spread his ingenuity worldwide.
Al-Jazari’s water clocks were the perfect gift, and were often inspired by preceding inventions, such as the water clock Harun al-Rashid, the Abbasid Caliph of Baghdad, sent to Charlemagne, the King of the Franks and Holy Roman Emperor, in 798. The lavish clocks were a symbol of wealth and power in the courts of its time. Gifts were often exchanged between those in power at the time to create alliances, show goodwill, and exchange technology to benefit both parties. Harun al-Rashid famously gifted Charlemagne a clepsydra, alongside many other gifts, including an elephant, perfumes, and a lavish robe. These gifts were a response to the highly valued royal red fabrics and embassy Charlemagne previously sent to Harun al-Rashid. The automata featured in the water clock sent to Charlemagne was never seen, which fascinated the Romans. This is an example of how the exchange of gifts not only strengthens relationships across the globe, but also helps spread the innovation worldwide and encourages other inventors to build from each other's work. The spread of the culmination of mechanical ingeniousness that the New Eastern world utilized was essential, as it inspired many engineers worldwide. It is noted that al-Jazari’s inventions have no trace of Western mechanics, but rather ancient Byzantine and Islamic mechanics. The art styles also have traits of Byzantine art styles in his manuscript, which builds upon the idea that culture and innovation is meant to be shared and evolved. The new perspectives and approaches to innovation can often inspire new ideas or additions.
What sets al-Jazari’s clocks apart from others, such as the one gifted to Charlemagne, is the way in which they displayed the time. Al-Jazari's elephant water clock featured an elaborate mechanical display that included an elephant figure that moved its trunk and head to indicate the time. The clock also included several other moving figures, such as birds and musicians, that helped to mark the passing of the hours. In contrast, Harun al-Rashid's water clock was a simpler and more straightforward device. It consisted of a large bowl or basin that was filled with water, which flowed through a small hole in the bottom of the bowl. The flow of water was regulated by a float that moved up and down, indicating the passage of time. The clock also featured several markers around the edge of the bowl that indicated the time of day. It is clear that al-Jazari was inspired by previous clepsydras; however, his clocks are much more advanced and feature a more elaborate mechanical display. This is another example of building upon previous works and improving or tweaking it to create an even better version. The basic water clock inspired al-Jazari, who then inspired many with his book.
Al-Jazari’s inventions ranged from locks, musical robots, to clepsydras, his favorite to design. His book contained blueprints to 100 ingenious devices, alongside beautiful illustrations to help conceptualize the invention. One of his other famous inventions is the "Peacock Water Clock," a complex and beautifully designed automaton that featured a peacock that would spread its tail feathers to indicate the passage of time. The peacock water clock was designed to wash the hands of the user, and it featured a number of intricate mechanical components that worked together to move water from one container to another. This elaborate multi use clock is yet another example of the impressive heights of automata engineering al-Jazari reached. He combines luxury with function, as all his innovations had practical use, while being works of art.
The Candle Clock of the Swordsman was another clock designed by al-Jazari, but rather than using water, it used a candle to determine time. In the center of the clock a large candle that was divided into sections was mounted on a stand. Each section represented a certain amount of time. As the candle burned, a small figurine mounted on a rotating platform moved around the base of the candle, indicating the passing of time. The Candle Clock of the Swordsman was actually designed to be used in a military setting, as it could be used to keep track of the time during the night. This invention shows that while all of al-Jazari’s inventions are practical, his inventions are throughout and especially designed to overcome issues. The candle clock was designed to be more accurate, which is better for military use, and usable in poorly lit areas. The typical sundials and water clocks weren’t as reliable in darker places, so al-Jazari remedied the issue with this well engineered clock.
Another one of al-Jazari’s impressive inventions is his invention of the combination padlock. At the time lock and keys were invented; however, this combination padlock became the most secure form of lock. When al-Jazari’s book was published in 1206, many people commissioned his works to be brought to life. There are four dials on the lid of the chest, which feature 16 letters from the Arabic alphabet that the dial can be turned to. The intricate pins, cylinders, discs and plates in the combination lock created a secure chest that only the user could access. One of the very few surviving chests is believed to be commissioned by a rich Christian individual, as the chest features biblical figures, as well as silver inlaid crosses. This exemplifies the reach of al-Jazari’s work. His inventions and technologies were admired by many across the globe. It’s even said that Leonardo de Vinci was especially interested in Muslim engineering and was likely inspired by al-Jazari’s work.
Al-Jazari’s legacy continues to live on in each component he invented, and those that were inspired by his work. His especially elaborate inventions were the perfect gift for high class individuals, including royalty. The exchange of gifts between different regions allowed for al-Jazari’s mechanical innovations to be introduced to many people. For many, the technology was never seen, and was at times referred to as “magic,” because the mechanical inner workings were not yet understood. Exchanging gifts in ancient times created a way to share knowledge, culture, and new ideas. The ancient clepsydra is a prime example of how this process works, and how sharing one's new mechanical developments enriches other communities through gift giving.
