Mocking Approval
Here we see a prisoner-fool in the stocks lickshining the frosty boots of a member of the female public who has come to gloat over him in the company of her manly boyfriend. At least by his humility and obedience the fool is earning the mocking approval of the happy couple, rather than their wrath!
Note how the semi-naked prisoner is compelled to lie in the freezing cold snow. At least his mocking visitors are well wrapped up against the cold!
