Selene was the divine personification of the Moon.
In the traditional pre-Olympian divine genealogy, Helios, the sun, is Selene's brother. After her brother, Helios, finishes his journey across the sky, Selene begins her own journey as night falls
upon the earth. Her sister, Eos, is goddess of the dawn.
Slowly, silently, now the moon
Walks the night in her silver shoon;
This way, and that, she peers, and sees
Silver fruit upon silver trees;
One by one the casements catch
Her beams beneath the silvery thatch;
Couched in his kennel, like a log,
With paws of silver sleeps the dog;
From their shadowy cote the white breasts peep
Of doves in a silver-feathered sleep;
A harvest mouse goes scampering by,
With silver claws, and silver eye;
And moveless fish in the water gleam,
By silver reeds in a silver stream.
