A young celebrated beauty, Madame Lescombat was having an affair with a man who, driven to desperate measures by jealousy, killed her husband.  He was executed by bludgeoning and the Wheel and Madam Lescombat was made to watch, her lover took two hours to be beaten to death.  She herself was found guilty of incitement and was sentenced to death but pleaded her belly.  After two months imprisonment it became clear that she was not pregnant and her execution was rescheduled.
Mme Lescombat was hanged on the scaffold at Greve Sq in Paris in 1755.  As was the custom at the time she was led to the scaffold after travelling there in the back of a wagon along with her coffin.  Her hands which were tied in fron of her were unbound and retied behind her back.  A scarf was tied around her face to hide her eyes, a noose placed over her neck and the rope hoisted so that she strangled rather than her neck broken (this was introdced much later on).
On the death of Lescombat:
"A truly vast crowd gathered excited in the place de Greve and those streets adjacent to it to witness her passage to the scaffold, as far back as the towers of Notre Dame...  ...When she climbed to the scaffold people clapped as if they were at the theatre.  During her execution, street vendors sold sketches of the dancing victim."
