like the turning of the wheel
When Ixion, king of Thessaly, fell in love with Hera, Zeus punished him for his effrontery by binding him to a wheel in Hades that revolved in perpetuity. In notable instances in the English literary tradition the mode of Ixion's torture is reconceptualized in psychological terms. Mary Shelley would surely have been familiar with King Lear's portrayal of himself as "bound/ Upon a wheel of fire" (IV.vii.46-47). It could well be that her own image influenced Percy Shelley's employment of the same figure in Prometheus Unbound (see I.139-42).
