What constellations are there in Ptolemy?

In addition to the twelve constellations, Ptolemy also listed the following thirty-six (now thirty-eight, Because Sagittarius is divided into three independent constellations): Ptolemy Andromeda | Aquarius | Aquarius | Sagittarius | Aries | Auriga | Shepherd | Cancer | Canis Canis | Goat | Capricorn | Cassiopeia | Centauri | Cepheus | Nanmian | Beimian | Cygnus | Orion | Pegasus | Perseus | Pisces | Sagittarius | Scorpio | Ursa Major | Ursa Minor | Virgo. In this constellation, the Southern Constellation, which is divided by Nicolas Louis de Lacaille into Carina, Tail and Ophiuchus, actually intersects with the zodiac, but it is not traditionally considered as one of the zodiac signs. Later, the constellations increased. Mainly to fill the gap between Ptolemaic constellations (because the ancient Greeks thought there was a dim blank area between bright constellations), and another reason was that when European explorers marched south, they could see some stars that they could not see before, so they had to join new constellations to fill the southern sky. Some nominated constellations were not finally adopted as official constellations. The famous one is Quadrans Muralis (now part of Capricorn)-the meteor shower of Quadrans is named after this constellation. There are also some less formal star arrangements called constellations, such as Beidou. In fact, the stars in the same constellation are irrelevant in most cases. They are only in the same line of sight, but in fact they may be far apart-if we were in another solar system of the Milky Way, the starry sky we saw would be completely different.
