Merket (instrument of knowing) for keeping time

“The merkhet or merjet ("instrument of knowing") was an ancient timekeeping instrument. It was used to track the alignment of certain stars, if they were visible, in order to approximate the time at night (10 stars for the 10 hours of the night, with a total of 24 hours including 12 hours for the day, 1 hour for sunset, 1 hour for sunrise). In this way, it was more efficient than other contemporary devices, such as sundials, which were rendered useless during the dark. The exact design of the merkhet consists of a horizontal bar, usually carved from wood or bone, with a plumb line hanging from a transverse hole at one raised end of the bar, attached to a controlling wooden handle. As deduced by texts and engravings on the inner walls of the temples of Dendera and Edfu, the merkhet was typically used in conjunction with a corresponding sighting tool, which the Egyptians called a bay, made from a specially cut palm-rib with a sliced "V" shape at one end. The two together could also be used, as appropriate, to determine North. For the operation to work, two merkhets were required, one aligned with Polaris, the North Pole star. If erected properly, and if a bay was on hand, one could estimate quite accurately the time by observing the transits of certain stars as they crossed the meridian and came into alignment with the two merkhets. A few merkhets have been excavated and preserved, including one that is on exhibition in the Science Museum in London. This particular exhibit dates to 600 BC, and, according to a related inscription, belonged to the son of a priest who hailed from a temple dedicated to the Egyptian god Horus, located close to Edfu in Upper Egypt.”

Tesoro perdido de la Gran Pirámide: El misterioso caso de las reliquias de Dixon

Hay una cierta percepción de la Gran Pirámide como una disposición absolutamente vacía de pasillos y cámaras vacíos, extrañamente desprovistos de artilugios e inscripciones que podrían ofrecer pistas sobre su construcción. En 1992, en cambio, el ingeniero alemán Rudolf Gantenbrink y su equipo ofrecieron a los espectadores de la actualidad su primer vistazo de artilugios […]

Stars and Sun Dials

To overcome the issues of no sun at night, the Egyptians invented something called a Merkhet.. This essentially uses plumb lines to make a North South line and time is measured by observing when certain stars pass the line.
