Leo is associated with fire, accompanied by Aries and Sagittarius, and its modality is fixed. Under the tropical zodiac, the Sun transits this area on average between July 23 and August 22 each year, and under the sidereal zodiac, the Sun currently transits this area from approximately August 16 to September 15. The constellation Leo is associated with the mythological Nemean lion. The lion is a very important and prominent symbol in Greek mythology. Its opposite sign is Aquarius.
Egyptians worshipped the constellation, which they referred to as "Knem", because it was present during the flooding of the Nile River. This event signified plentiful harvests for the upcoming year, and the people interpreted it as a gift from the earth. Ruler of Egypt, Tutankhamun's gold throne features lion heads where the seat and front legs meet, as well as clawed feet at the end of each leg, symbolizing power and royalty.
