"Probably about 500, probably less, in England, and they weren't burned: they were hanged."
That sentence is ambiguous. It probably means that probably less than 500 witches were hanged in England, and none were burned. But, that just speaks to the form of execution for witchcraft. Burning at the stake as a punishment (for religious crimes) in Europe goes back to Roman times. Joan of Arc wasn't burned for being a witch; she was convicted of wearing men's clothing. However, it was still political at base.
And, the number of people executed during the Spanish Inquisition has probably been exaggerated. Those numbers are dwarfed by the number of people killed in the Crusades within Europe against heretics (other Christians) such as the Albigensians and Cathars. There were more Cathars killed in one go than almost half the entire number of witches killed in England.
From May 1243 to March 1244, the Cathar fortress of Montségur was besieged by the troops of the seneschal of Carcassonne and the archbishop of Narbonne.[68] On 16 March 1244, a large and symbolically important massacre took place, where over 200 Cathar Perfects were burnt in an enormous pyre at the prat dels cremats ("field of the burned") near the foot of the castle.[68]
Apart from the annihilation of Christian heretics, there was also the burning massacre of Jews in England during the 12th century. That was mob violence, though. Burning at the stake was a particularly symbolic form of execution. Dead is dead, whatever the reason for or manner of execution.
Anyway, England is not what comes to mind when it comes to witch burnings. In the US, we think of Salem, MA
. Iirc, only 20 or so people were executed as witches (by hanging, of course). Several others died while incarcerated.
From Europe, in general, we have gotten our ideas of "medieval torture," maybe in the Tower of London. It's interesting how our mythology is fashioned. Fifteenth-century fantasies are more well known than 18th century realities.
