I enjoyed your article ‘The Psychology of a Witch Hunt’ (August). However, while this was about the well- documented Salem witch trials, we should remember that those victims numbered just 20. In western Europe, over 200,000 people were tortured, hanged and drowned as a result of witchcraft accusations from 1484 to 1750. Matthew Hopkins was responsible for over 300 executions and fear gripped Britain’s East Anglia for 14 months. He was paid to invent accusations, carry out torture and extract confessions from innocent people. Hopkins had 68 people put to death in Bury St Edmunds alone, 19 hanged in Chelmsford in a single day, and then set off for Norfolk and Suffolk. The victims were overwhelmingly female and poor. Let us not forget those who died here. Salem may be famous, but it was the tip of the iceberg.
