As we said in the previous paragraph, there is no record of their being an hourglass in Europe before the Early Middle Ages. And the very first hourglass is said to have been made by a french monk named Liutprand during the eighth century A.D. But it wasn’t until the 14th century that Hourglass clocks were seen more commonly.
