The Lion, long considered the “king of beasts,” rules the sky from July 23 to August 23.

Leo was one of the earliest recognized constellations, with archaeological evidence that the Mesopotamians had a similar constellation as early as 4000 BCE. The Persians called Leo Ser or Shir; the Turks, Artan; the Syrians, Aryo; the Jewish, Arye; the Indians, Simha, all meaning “lion”. In Babylonian astronomy, the constellation was called UR.GU.LA, the “Great Lion”; the bright star Regulus was known as “the star that stands at the Lion’s breast.” Regulus also had distinctly regal associations, as it was known as the King Star.

In Greek mythology, Leo was identified as the Nemean Lion which was killed by Hercules during one of his twelve labours, and next put into the sky.

The Roman poet Ovid called it Herculeus Leo and Violentus Leo. Bacchi Sidus (star of Bacchus) was another of its titles, the god Bacchus always being identified with this animal. However, Manilius called it Jovis et Junonis Sidus (Star of Jupiter and Juno).

In standard western astrology, the Sun is considered to be in the sign Leo from July 23 to August 23. People born under this sign are considered confident, ambitious, generous, loyal, and encouraging though they can also manifest less-desirable characteristics and be considered pretentious, domineering, melodramtic, stubborn, and vain.
