When Was the Merkhet Invented?

Egyptian 'star clock' (merkhet), c 600 BC. This star clock or merkhet was used to measure the time at night. The Egyptians timed the apparently regular movements of the stars across the sky using an equal interval timer such as a water clock, and this set the basis for the Egyptian time-keeping system.

When were merkhet invented?

The Sumerian culture was lost without passing on its knowledge, but the Egyptians were apparently the next to formally divide their day into parts something like our hours. Obelisks (slender, tapering, four-sided monuments) were built as early as 3500 BCE.

What did the merkhet do?

The merkhet or merjet (Ancient Egyptian: mrḫt, 'instrument of knowing') was an ancient surveying and timekeeping instrument. It involved the use of a bar with a plumb line, attached to a wooden handle.
