Theseus and the Bed of Procrustes
On his journey to Athens, the hero Theseus encounters the bandit Procrustes, who tortured travelers by forcing them to fit into one of two iron beds. Theseus defeats the rogue by subjecting him to his own cruel device, ensuring the safety of the road for future pilgrims. This final labor established Theseus as a champion of justice before he entered his father's city.
