Nisus’ Purple Hair of Invincibility Stolen by His Daughter Scylla
King Nisus of Megara possessed a magical lock of purple hair that guaranteed the safety of his life and his kingdom. During a siege by King Minos of Crete, Nisus' daughter Scylla fell in love with the enemy king and cut the lock from her father's head as a gift for Minos. Repulsed by her betrayal, Minos rejected her, and both father and daughter were eventually transformed into birds.
