In ancient Greek mythology and religion, Eos is the goddess and personification of the dawn, who rose each morning from her home at the edge of the river Oceanus to deliver light and disperse the night. She opened the gates of heaven for her brother Helios, the sun, to pass through, and was imagined in poetry and art as a radiant, often winged goddess driving her horse-drawn chariot across the sky, bringing with her the colours and dew of morning.
