In Roman mythology Aurora is the goddess of which period of the day?

Aurōra is the Latin word for dawn, and the goddess of dawn in Roman mythology and Latin poetry.

In Roman mythology, Aurōra renews herself every morning and flies across the sky, announcing the arrival of the Sun. She has two siblings, a brother (Sol, the Sun) and a sister (Luna, the Moon).

Aurōra appears most often in sexual poetry with one of her mortal lovers. A myth taken from the Greek by Roman poets tells that one of her lovers was the prince of Troy, Tithonus. Tithonus was a mortal, and would therefore age and die. Wanting to be with her lover for all eternity, Aurōra asked Jupiter to grant immortality to Tithonus. Jupiter granted her wish, but she failed to ask for eternal youth to accompany his immortality, and he continued to age, eventually becoming forever old. Aurōra turned him into a cicada.
