The origin of constellations

Constellations originated in Babylon, one of the four ancient civilizations, and the Babylonians put forward 30 constellations around 1000 BC. The Tigris River and the Euphrates River flow from northwest to southeast and into the Persian Gulf, so they are also called the two river basin areas. After the culture of the two river basins spread to ancient Greece, it promoted the cultural development of ancient Greece. Ancient Greek astronomers supplemented and developed the Babylonian constellation and compiled the ancient Greek constellation table.

In the 2nd century A.D., Ptolemy, an ancient Greek astronomer, synthesized the astronomical achievements at that time and sorted out 48 constellations. After the Middle Ages, European capitalism rose and needed to expand outward, and the navigation industry was greatly developed. Ships sailing at sea need navigation at any time, and stars are the best street lamps. Among the stars, this constellation has a special shape and is the easiest to observe. Therefore, constellations have aroused widespread concern.
