As the story goes, Scylla was the daughter of Nisus (Nisos) the King of Megara, who possessed a single lock of purple hair which granted him and the city invincibility. When Minos, the King of Crete, invaded Nisus's kingdom, Scylla saw him from the city's battlements and fell in love with him. In order to win Minos's heart, she decided that she would grant him victory in battle by removing the lock from her father's head and presented it to Minos. Disgusted with her lack of filial devotion, he left Megara immediately. Scylla did not give up easily and started swimming after Minos's boat. She nearly reached him but a sea eagle, into which her father had been metamorphosed after death, drowned her. Scylla was transformed into a seabird (ciris), relentlessly pursued by her father, who was transformed into a sea eagle (haliaeetus).
Ah cease, rash youth! desist ere 'tis too late,
Fear the just gods, and think of Scylla's fate!
Chang'd to a bird, and sent to flit in air,
She dearly pays for Nisus' injur'd hair!
