(Greek mythology) the winged goddess of the dawn in ancient mythology; daughter of Hyperion; identified with Roman Aurora
"In Greek mythology, Eos was the winged goddess of the dawn who traveled across the sky each morning."
The Greek goddess of the dawn; daughter of Hyperion and Theia, sister of Helios and Selene, wife of Astraeus (god of the dusk), and mother of the four Anemoi ("Winds"), and the five Astra Planeta ("Wandering Stars/Planets"). Her Roman counterpart is Aurora.
"The poet invoked Eos to ask for a gentle dawn that would softly usher in the new day."
The word comes directly from Ancient Greek, where it originally referred to both the dawn and the goddess who personified that time of day. It entered English as a poetic term for the early morning light, sharing its roots with the Latin name Aurora.
