Breaking on the wheel was the most horrific punishment ever visited on a convicted criminal. It was a form of crucifixion, but with several cruel refinements; in its evolved form, a prisoner was strapped, spreadeagled, to a large cartwheel that was placed axle-first in the earth so that it formed a rotating platform a few feet above the ground. The wheel was then slowly rotated while an executioner methodically crushed the bones in the condemned man’s body, starting with his fingers and toes and working inexorably inward. An experienced headsman would take pride in ensuring that his victim remained conscious throughout the procedure, and when his work was done, the wheel would be hoisted upright and fixed in the soil, leaving the condemned to hang there until he died from shock and internal bleeding a few hours or a few days later.
“Breaking” was reserved for the most dangerous of criminals: traitors, mass killers and rebellious slaves whose plots threatened the lives of their masters and their masters’ families. Yet in the case of one man who endured the punishment, a slave known as Prince Klaas, doubts remain about the extent of the elaborate conspiracy he was convicted of organizing on the West Indian island of Antigua in 1736. The planters who uncovered the plot, and who executed Klaas and 87 of his fellow slaves for conceiving of it, believed it had as its object the massacre of all 3,800 whites on the island. Most historians have agreed with their verdict, but others think the panicky British rulers of the island exaggerated the dangers of a lesser plot—and a few doubt any conspiracy existed outside the minds of Antigua’s magistrates.
