In Greek mythology, Eos is the personification of what part of the day?

Eos was a Titan goddess in Greek mythology, daughter of the Titans Hyperion and Theia. She was the goddess of the dawn and had two siblings; Helios, god of the sun; and Selene, goddess of the moon. She was married to Astraeus, god of the dusk and together, they had numerous children that represented everything that occurred during the union of the dusk and the dawn, i.e. the twilight. Among her children were the four Anemoi (winds), as well as Eosphorus (the Morning Star) and the Astra Planeta (wandering stars or planets). She was described as having rosy fingers, a light pink gown woven with flowers, wearing a tiara and having large white-feathered wings.
