Also known as Charles the Great (747 - 814) , Charlemagne was the founder of the Frankish State and came to be known as the Emperor of Rome having successfully extended his reign over Western Europe for the first time since the fall of the (Western) Roman Empire.
Charlemagne was a contemporary of Abassid Caliph Haroon Al-Rasheed who gifted the Frankish monarch a lavish gift set compromised of an Elephant a marvelous Mechanical Hydrolic Clock in the year 807.
This advanced mechanical device was received by the Franks with great wonder as it's moving mechanical parts made sounds and triggered a sequential spectacle that set various weights and bells that animated twelve horsemen made out of brass that would come out from twelve windows at noon.
The Elephant Clock was a testament to the Muslim world's technological advance and intellectual brilliance. In fact, the many components and attributes within its ingenious design also celebrate the cultural diversity and intellectual reach of its inventor because the clock was compromised of various sciences and principles derived from the ancient Greeks (such as the ancient Clepsydra water clocks), the elephant used to deliver the clock was from India, the clock itself was adorned with an Egyptian phoenix as well as figures from Arabian folklore and Chinese culture (dragons).
This was in many ways the first international clock known to mankind.
