Asteria was daughter of titans Koios and Phoebe, granddaughter of Ouranus and Earth and sister of Leto who gave birth to Artemis and Apollo. Koios was responsible for the quality of things. His name in ionic dialect is Koios but in aiolic dialect is Poios which means quality (κοῖος = ποῖος = quality). His wife, Phoebe, had the abilities of clearness and diaphaneity. Leto had the abilities of night and lethe and Asteria was responsible for the movement of the stars and their appearance. So quality and diaphaneity born night and stars.
