Leo a.k.a. the best one
Actually I am a double lion because my birthday happens to fall within Leo in both tropical and sidereal astrology. So I'm twice as best.
In the second century CE, Ptolemy of Alexandria, while making up astrology literally from his ass, based all of his 'calculations' on Hippocartes' trigonometry. It is only because of astrology that we can now credit Hippocartes or his teachers for creating trigonometry. I think it's cool that junk science preserved real science in that case. It reminds me of how faith organizations have often preserved civility throughout the ages.
Aries, don't know what that means, one of you that knows this crap should tell me.
Aries (♈) is the first astrological sign in the Zodiac, named for the constellation of Aries, called "The Ram" in the Greek tradition, after the golden ram that rescued Phrixos, taking him to the land of Colchis.
In tropical astrology, this sign is no longer aligned with the constellation as a result of the precession of the equinoxes. Under the tropical zodiac, the Sun is in Aries roughly from March 21 to April 19, by definition beginning at vernal equinox. Under the sidereal zodiac, it is currently there roughly from April 15 to May 15.
Individuals born when the Sun was in this sign are considered "Aries individuals" or "Arians". In Western astrology, Aries is considered a "masculine", positive (extrovert) sign. It is also considered a fire sign, and is one of four cardinal signs. Aries is ruled by the planet Mars. Being the first sign in the zodiac, Aries is associated with the astrological first house. The Sanskrit name of Aries in Hindu astrology is Meṣa.
Generally, Aries is considered compatible with same element signs, Sagittarius, Leo and Aries itself. These signs share a fiery demeanor and are believed to relate with each other on that merit.
