The Grate

Tied to a iron "bed" 
Feet and legs were greased 
And then a brasier 
Was placed underneath 
Decompose the melting flesh 
Repulsive stench 
Of hot roasting flesh 
Flesh is roasted, bones are showed 
Limbs are lacerated, bodies are desecrated 
The fire would cause burns if you are guilty 
But leave you unharmed if you are innocent 
Innocence presupposed 
Withstand any trial
