The daughter of HYPERION and THEA, she’s married to the blustery Wind God ASTRAEUS and has four windy sons: BOREAS, EURUS, NOTUS and ZEPHYRUS. She’s a bit flighty herself, having been cursed with nymphomania by APHRODITE.
She pleaded with ZEUS to grant him immortality, but forgot about the ageism clause. So poor TITHONUS just got older and older and increasingly withery. Eventually the Gods took pity and turned him into a cicada.
So it’s not surprising that poor EOS carries on weeping. But this in turn ensures there is never any shortage of dew. In Roman times she was known as AURORA, but we have yet to find a happy ending.
