Zeus employed the Harpies, wind spirits, to punish bad guys. Eventually, the Argonauts found them fouling King Phineas' food, and had them driven off. They escaped death when their sister Iris, the Rainbow, intervened. They ended up on some barren Greek islands.
I imagine them passing their retirement years in typical old lady pursuits, dabbling in music, maybe reading a bit. They take a special interest in gardening, perhaps to atone for their their disgusting behavior with King Phineas.
This wall hanging is entitled "The Harpy in her Garden."
I still have one left.
