Around 1500 BC, ancient Egyptians developed the decan star system, which was crucial for timekeeping and the creation of calendars. This system divided the night sky into segments based on the rising of specific stars, allowing Egyptians to track time and seasons accurately. The innovation of decans played a vital role in agricultural planning and religious practices, influencing the daily lives of the ancient Egyptians.

The Egyptian decans and star clocks from 1500 BC influenced early Mediterranean poetry with motifs of time and fate. Poets like Homer incorporated celestial imagery, reflecting humanity's quest to understand their place in the cosmos, intertwining mythology and astronomy in their narratives.
