More than 2000 years ago, the Greek astronomer Hipparchus (BC 190 ~ BC 120) marked the position of the sun on the ecliptic, divided the ecliptic into 12 segments, divided the spring into 0, and made a palace every 30 degrees from the vernal equinox (that is, the zero degree of the ecliptic).

In turn, Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius, Pisces and other houses are called the zodiac. There are twelve constellations in all. Babies born when the earth moves to every fraction (constellation) will always have some similar characteristics when they grow up, including behavioral characteristics.

By connecting these associations (rich imagination and creativity) in series, these constellations are visualized; It also adds the color of myth and becomes an important part of culture (mainly Greek and Roman mythology). This set of numerology has been developed and circulated for at least five thousand years, represented by these twelve constellations respectively.
