@antiquidons Hipparchos concluded that the star Spica, part of the constellation #Virgo, had moved 2° relative to the #AutumnalEquinox.
When he compared the time it took the Sun to return to an #equinox with the time it took the Sun to return to a fixed star, he found a slight discrepancy. The equinoxes were moving ("precessing") through the zodiac, and that the rate of precession was at least 1° in a century. In other words: a full cycle through the zodiac is completed every 36,000 years.
Happy #Equinox to all who celebrate. Today, day and night are of approximately equal length. From now on, the days get shorter in the Northern hemisphere as #Persephone descends to the underworld and Demeter's sadness halts any plant growth until her daugher returns in Spring. Unless it is actually in winter that Persephone is with #Demeter. Both interpretations are compelling.
