How Did the Cygnus Constellation Get Its Name?


Cygnus is a constellation visible in the Northern Hemisphere, named after the Latin word for “swan”. But how did this constellation get its name? Let’s explore its origins.

The Mythological Origin of Cygnus

In Greek mythology, the story of Cygnus is linked to the story of Orpheus, a legendary musician and poet. According to the myth, Orpheus fell in love with a woman named Eurydice, who died from a snakebite. Overwhelmed with grief, Orpheus traveled to the underworld to try to bring her back to life. He charmed the gods with his music and was granted permission to take Eurydice back to the world of the living. However this was under the condition that he could not look back at her until they reached the surface.

Unfortunately, Orpheus couldn’t resist the temptation to look back, and he lost Eurydice forever. In his despair, he wandered the earth until he was attacked and killed by a group of Thracian women. His tragic story moved the gods. They decided to turn him into a swan and place him in the sky as a constellation.
