Who invented the constellation?

Western constellations originated in ancient Greece, and the earliest mention of constellations was in a poem Phaenomena written by the Greek poet Aratus in 270 BC. As can be seen from this poem, the word constellation was known to mankind before Aratus.

The constellation mentioned by Aratus has no stars at all near the south celestial pole. This may be because these stars are all below the horizon of the region where the constellation name is located. From these unmeasurable horizons, we can infer that the people who named the constellations probably lived at about 36 north latitude, that is, south of Greece and north of Egypt, where Babylon and Sumer were located.

Due to the precession of the earth's rotation, the north and south poles of the earth will deviate periodically with time. According to calculations, this unexplored celestial sphere was just above the south celestial pole in 2000 BC, which was also the time when ancient Babylonians and Sumerians lived.

Based on this, we have great reasons to believe that Greek constellations originated in ancient Babylon and Sumer. The knowledge about constellations later spread to Egypt and was known by some Greek scholars who lived there at that time.

In A.D. 150, the Greek scientist Ptolemy compiled an astronomical book named "Astronomical Table", which summarized the astronomical knowledge of the Greeks at that time, including the names of 48 constellations and 1022 stars, and the estimation of their luminosity.

The origin of tarot cards should be roughly as follows: first of all, the tarot card's Grand Akana originated from the ancient Jewish Kabaka. Because of the frequent contact between ancient Jews and ancient Egyptians, they also absorbed many Egyptian religious symbols. With the frequent wars in the Middle East, the predecessor of Tarot almost disappeared. Later, gypsies didn't know how to use tarot cards, but I believe they probably didn't know much about the philosophical level of tarot cards, so they used it as a divination tool. It spread to Europe between12nd century and14th century, and was soon banned by the Holy See. After the church's power weakened, tarot cards developed again, and new tarot cards were introduced one after another. Especially at the end of19th century, the research on tarot cards became more systematic after the researchers linked tarot cards with the scroll cultural relics of ancient Jewish esoteric religion, and Ryder Tarot cards were one of the representatives.
