Leo. Artwork representing Leo the Lion (23 July to 23 August), 5th of the 12 star signs. Astrologers claim that the star sign (also called sun sign) that you are born under will influence your character and destiny. Each sign is associated with one of the classical elements (fire, earth, air, or water). Leo is a fire sign. The star signs originated as the 12 constellations (star patterns) of the zodiac, the path that the Sun traces in the sky as the Earth orbits the Sun during the year. Ancient astronomers used them to track the passing of the year. Their shapes in the sky inspired many myths. R550/508-519 shows artworks of all 12 star signs.
