## Definition

the goddess of the dawn in ancient Greek stories. In literature, writers use this name to describe the very first light of the morning.

For teachers: the personification of the dawn in Greek mythology, often depicted as the sister of Helios and Selene. In literary contexts, it serves as a poetic metonym for the break of day.

## Examples

- The sky turned pink as Eos rose over the hills.
- The poet described the first light of Eos touching the marble columns of the temple.
- In Homeric epics, Eos is frequently described as 'rosy-fingered', a vivid epithet that captures the streaky, colorful appearance of the horizon at daybreak.

## Usage notes

- Usually treated as a proper noun and capitalized; when used metaphorically for the dawn, it remains uncountable.
