Selene was the Greek goddess of the Moon. According to the poet Hesiod, Selene was the daughter of the Titans Theia and Hyperion, making the goddess the sister of Helios (the Sun) and Eos (the Dawn). However, other ancient sources claim that she was the child of Pallas and Euryphaessa.

Homeric Hymn to
Selene
"Muses, sweet-speaking daughters of Zeus Kronides
and mistresses of song, sing next of long-winged Moon!
From her immortal head a heaven-sent glow
envelops the earth and great beauty arises
under its radiance. From her golden crown the dim air
is made to glitter as her rays turn night to noon,
whenever bright Selene, having bathed her beautiful skin
in the Ocean, put on her shining rainment
and harnessed her proud-necked and glittering steeds,
swiftly drives them on as their manes play
with the evening, dividing the months. Her great orbit is full
and as she waxes a most brilliant light appears
in the sky. Thus to mortals she is a sign and a token."
Selene, as the personification
of the Moon, was an influential goddess. One of her best known myths
involves the handsome Endymion. The moon-goddess fell in love with this
mortal, and she therefore engaged in an affair with Endymion that resulted
in the birth of fifty daughters. But Endymion was, alas, human, and
so susceptible to aging and eventually death. Selene could not bear
the thought of this cruel fate. She made certain that Endymion would
remain eternally youthful by casting a spell that would cause him to
sleep forever. In this way, Endymion would always live, sleeping through
the ages.
Some Classical authors identified Selene with the Olympian goddess Artemis.
Selene was called Luna in Roman mythology.
