According to Restless Dead by Sarah Iles Johnston, aōrai were associated with birds of prey - and particularly with nocturnal raptors such as the owl (an interesting comparison is the Babylonian Lamashtu and the Semitic Lilith, both female demons who attacked women and children, and who often were pictured with the features of a bird of prey). So I let Erigone escape in the form of an owl.
Well-matched pair we got there...
I remember, Lilith had owl bird feet and wings on her back.
Ha! He's smitten. ♥️
