Pegasos

Pegasos is the original Ancient Greek form of the name Pegasus, best known as the name of the winged horse in Greek mythology. The Greek name Πήγασος (Pḗgasos) is thought to derive either from πηγός (pegós) meaning "strong" or from πηγαῖος (pēgaîos) meaning "from a water spring". The latter connection reflects the mythological birth of Pegasus, who sprang from the blood of the Gorgon Medusa after she was beheaded by the hero Perseus — a spring-like gushing forth of life.

Etymology

As recorded on Wiktionary, Pegasos is the direct Latin transliteration of the Ancient Greek Πήγασος. In English, the name is often used as an alternative spelling of Pegasus, particularly in academic or mythographic contexts that favor the original Hellenic form. The name's dual etymology — linking to strength (πηγός) and springs (πηγαῖος) — mirrors the dual nature of the mythological being: a powerful, invincible steed that also created the Hippocrene fountain on Mount Helicon by striking the ground with its hoof.

Mythological Significance

In Greek mythology, Pegasos was a divine winged horse, child of Poseidon and Medusa. After Perseus cut off Medusa's head, Pegasos emerged from her body along with the warrior Chrysaor. Pegasos later became the companion of the hero Bellerophon, helping him defeat the Chimera. As a symbol of poetic inspiration, Pegasos carries deep cultural resonance. The constellation Pegasus, named after the horse, still bears the original Greek form in its official Latin designation as Equus Pegasos in older star atlases.
