Byblis. In Greek mythology, Byblis or Bublis was a daughter of Miletus.
Her mother was either Tragasia, daughter of Celaenus; Cyanee, daughter of the river-god Meander, or Eidothea, daughter of King Eurytus of Caria. She fell in love with Caunus, her twin brother.
The most elaborate interpretation of her story is that of Ovid, and runs as follows. Byblis acknowledged her love for Caunus, and despite her initial efforts to convince herself that her feelings were natural, she realized the inappropriateness of them.
Unable to keep her love for Caunus a secret from him any longer, she sent him a long love letter through a servant giving examples of other incestuous relationships between the gods. Disgusted, he ran away.
Believing that she could yet make him love her, she was determined to try to woo him once more. When she found out that he had fled, she tore her clothes and stripped naked in sorrow and was driven into madness. She followed him through much of Greece and Asia Minor until she finally died, worn out by her grief and the long journey. As she had been constantly crying, she was changed into a spring. Parthenius of Nicaea cites two versions of Byblis' story, one of which is generally the same as that recounted by Ovid, but ends with Byblis hanging herself with her girdle. In the other version, it is Caunus who instigates the incest, but Byblis still seems to return his affectio
