Greek Myths About Constellations

Most of the astronomical objects’ names that we use today come from Ancient Greece. Orion, Centaurus, Pleiades, Pegasus, Andromeda… Even the planets in our Solar System are named after Roman gods. Mars is Ares, Neptune is Poseidon, and Venus is Aphrodite in Greek Mythology. So why does today’s astronomy have such a strong relationship with the Greek culture?

Homer and Hesiod, the two pillars of Greek Mythology, are one of the reasons why. In both poets’ creations, constellations were mentioned as mythical characters. Orion Constellation, for example, was on the shield of Achilleus in Illiad, which was made by Hephaistos.
