The fourth coin from the "Calendars" series.  A beautiful oxidized coin dedicated to the Egyptian calendar. Thanks to the high relief and the addition of resin it can become a unique coin in the collection. The mintage is only 700 pieces.  The Egyptians were the first to create a solar calendar. Actually, it is a combination of a lunar-solar calendar and an agrarian calendar, based on the cycle of the Nile floods. It was created around 3000 years BC. The Egyptian calendar year was divided into 3 seasons of 4 months each: - achet, the season of flooding- peret, the season of receding waters (season of germination and growth) - winter- szemu, the harvesting season - summer. Each of the months, which had 30 days each, was given a name according to its order in the season, e.g. 1 achet, 2 achet, 3 achet, 4 achet, 1 peret, etc. In addition, 5 days were added to these 12 months, the so-called epagomenai - days of birth: Osiris, Horus, Seth, Isis and Nephthys. Interestingly, the Egyptian calendar is still used in the Coptic Church (in Ethiopia). Also based on it is the Armenian calendar, which was used in astronomy until the time of Copernicus (he kept his diary of observations in it). Both the obverse and reverse are decorated with Egyptian symbols.
