Egypt that taught the world..
In the picture is the best witness to the truth of this statement. In picture No. 1, an Egyptian solar clock from the era of the Egyptian king (Merenptah), dating back to the year 1200 BC and located in the Rijksmuseum, Amsterdam. In the second picture is a copy of the Egyptian clock, but it dates back to the tenth century AD from the Byzantine era and is found. In the Istanbul Museum in Turkey, the time difference between the two clocks is 2000 years, but Egyptian technology and innovations have remained the mainstay of human siege. The calendar that the world uses in our current era, which consists of 365 days and divides the day into 24 hours, and the clock that calculates time, and the leap year consisting of 366 days, all of these astronomical innovations are what our world inherited. In Egyptian civilization, the Egyptians were the first to divide the year into 365 days Unlike their neighbors in the Eastern civilizations, in which the year was essentially 354 lunar days, the Egyptian calendar was based on calculating the cycle of the star Sirius and its rising with the sun every year. From here began the story of the calendar consisting of 365 and a quarter days. Therefore, they noticed that the appearance of the star (Sophet) or Sirius was delayed by a day. Every four years, the astronomers-priests from all the cities of Egypt met during the reign of Ptolemy III in the year 238 BC in the city of Canopus, and they agreed on a major matter: reforming the calendar and adjusting the measurement of cosmic time, by adding a day every four years to the Egyptian calendar, which consists of 365 days. After they noticed that the star Sirius was delayed in its appearance after the beginning of the year every four years, from here began a new chapter in the history of astronomy and the calendar, which is the birth of what we know today as the leap year, which consists of 366 days every four years. Instead of 365 days, which many do not know when, by whom, or why she was born, the priests of Egypt issued
In the year referred to, its astronomers issued the famous Canopic Decree, and several copies were distributed to the temples and major cities of Egypt. We were lucky and found several copies of the decree that was issued to reform the calendar and approve the leap year. The Romans adopted this reform later in the era of Julius Caesar, who founded the calendar. The Julian calendar, which was later called the Gregorian calendar, is our current calendar. Egypt is the one that gave the current world the calendar that we use, and its civilization was the first to divide the day into 34 hours, and invented the first clocks that measure the length of the day. Therefore, the world today, as experts say, owes the Egyptian civilization for all these achievements. ,.
