Pierre de Lancre

Pierre de Rosteguy de Lancre or Pierre de l'Ancre, Lord of De Lancre (1553–1631), was the French judge of Bordeaux who conducted the massive Labourd witch-hunt of 1609. In 1582 he was named judge in Bordeaux, and in 1608 King Henry IV commanded him to put an end to the practice of witchcraft in Labourd, in the French part of the Basque Country, where over four months he sentenced to death several dozen persons.
