Clearly, sitting on the fence, hedging your bets, watching which way the wind blows, is a sin which leads to hell and a suitably inverted punishment.
For having never run in one direction or another in your life (‘never-living sprinters’), you are condemned to an eternity of being spurred to run by the stinging torments of flies and wasps.
‘Rooted to the spot,
I saw and knew for certain that this race
Of never-living sprinters were the ones
Who once believed fence-sitting no disgrace,
But now they sit no more. The whole bunch runs
Naked, with flies and wasps to stimulate
Their actions at long last…’
