So awesome was deciphered ancient calendar glades. Now, Rybakov was able to draw an analogy between the ornaments on this vessel, and IV in the jar., Found back in 1899 archaeologist V. Hvoyko in with. Daisies near Kiev. Pitcher hit researchers unusual patterns, which no one could decipher. Sophisticated ornamental signs marked on the vessel wall in two rows. The top row shows two of the cross, a hexagon - a sign of thunder and lightning, the young tree, ears, sickles, in the second row - 96 squares and wavy lines. BA Rybakov, speculated that the squares represent days, and identified a hexagon with the holiday storm and thunder, which in the Julian calendar falls on July 20 (Elijah's Day). The holiday of Ivan Kupala Day is separated from Ilina at 27 days, and the jar between the hexagon and two crosses, as is often designated day, Midsummer, there are 27 squares. Between the images of the tree, symbolizing Yarily day, and hexagon (Elijah's Day) is 46 squares, which corresponds to 4 June. And we know from the chronicles that day Yarily fell on that date. Consequently, we have - the exact calendar from May 2 to August 7. Even signs of rain - wavy lines - depicted in the top row of the ornament at a time when moisture is most needed wheat: 20-30 May, 11-20 June, 4-6 July. More rains are no longer needed, and signs of rain are transferred from the upper to the lower number - into the ground before harvest.Astronomy as a science originated in ancient times. She accompanied mankind throughout the development of civilization from its very origins. The need for a fixed time interval forced primitive peoples to create a calendar system, constantly improve them, and each time to make more accurate calendars. Thus were laid the beginnings of astronomical knowledge of our ancestors.
