Toward the end of the article there are descriptions of Al-Jazari water clocks but did not mention about the infamous Alhambra Palace lions water clock, and most likely it was based on Al-Jazari inventions. Since Alhambra Palace construction was started in the same century of Al-Jazari death (13th century AD) it's very plausible that it's based on his work.
Al-Jazari invented hundreds of inventions including mechanical robots that were said to be copied by later scientist and engineers including Leonardo da Vinci, and we know that good artists copy but great artists steal [1].
During a visit to Alhambra Spain it was claimed the water will gush out from each of the lion figure's mouth fountain for every hour, in sequence of turns not unlike our clock now but it all based on water. Perhaps this is possible due to the Al-Jazari water clock invention but no one know how it was originally working [2].
It's a shame that indispensable knowledge like this has been lost forever and this also happened to the earliest earthquake sensor instrument invented by Zhang Heng back in 132 A.D. He called his seismoscope Houfeng Didong Yi, meaning an "instrument for measuring the seasonal winds and the movements of the Earth." Now the working replica has been recreated but only until very recently they had managed to recreate the functioning replica but knowledge regarding the actual original working mechanism has been lost forever [3]. Ironically after more than 2000 years later and USD1 Billion spent for the earthquake sensors system installations, the latest system with 15K sensor stations throughout China, it still cannot predict the earthquakes but only provide alerts to the authority after the main earthquake has happened somewhere in China [4],[5].
