Extended information
The origin of constellations: In order to facilitate the study and observation of many stars in the sky, astrologers of the Mesopotan civilization divided the starry sky into several areas. Each area is A zodiac sign.
It is difficult to say exactly when humans began to have the concept of constellations. This type of astronomical knowledge was understood by people long before historical records. The names of the constellations are likely derived from early sailors. In civilizations in different regions, the origins of constellations may be completely different, but with the expansion and mutual influence of civilizations, the culture of constellations also includes a process of integration.
Constellation symbols:
1. Libra
The Libra symbol symbolizes balance. The constellation symbol of Libra is clear at a glance. You can tell at a glance that it is a balanced scale, and what is required is how to balance the two sides of the scale.
2. Scorpio
The Scorpio symbol symbolizes mystery. The symbol is actually a "snake", because snakes have been regarded as symbols of "wisdom" and "sin" in ancient times. It is well known that the main culprit was the reason that Adam and Eve, the ancestors of mankind, were expelled from the Garden of Eden. If you can't stand the temptation of snakes, you will eat the fruit of wisdom and make a big mistake.
