I remember that Tesibius from Alexandria after visiting the Temple of King Ladon, decided to engineer his water clock for measuring accurately time.
Later Archimedes inspired by Tesibius’ work designed and engineered his clock.
The Navy’s Laboratories have built a prototype of King Ladon’s Water Clock. The prototype is a replica of King Ladon’s Water Clock developped around 27000BC. Note that even today we are not able to replicate the time precision they achieved with the technology they had available at that time.
Amazingly it has an Atomic precision, probably due to the magical power King Ladon himself possessed.
