Arachne
It has also been suggested that Jeremias Gotthelf's nineteenth century novella, "The Black Spider", was heavily influenced by the Arachne story from Ovid's "Metamorphoses". In the novella, a woman is turned into a venomous spider having reneged on a deal with the devil.
Achlys
She may also have been the goddess of deadly poisons as presented by Nonnus. According to the "Dionysiaca", Hera procured from Achlys treacherous flowers of the field which shed a sleeping charm over the sons of the Nymphs Lamusides (nurses of Dionysus). The goddess then distilled poisoned drugs over their hair and smeared a magical ointment over their faces, changing their human shape into that of the Horned Centaurs.
