[3] In Finland, the Easter witch custom (virvonta) comes from the old Karelian Orthodox Christian tradition.
In the 17th century, fear of witches caused brutal persecution of innocent women and trials.
Because of this during this time period doors and dampers were secured to guard against the travel of the witches to Blåkulla to meet the Devil.
[4] In Sweden and Finland, it is an Easter tradition for children to dress as witches, old women and old men and go door to door for treats similar to the trick-or-treating tradition of Halloween on Maundy Thursday or the day before Easter (Holy Saturday).
[2] Related to warding off witchcraft and at a similar time of year is the Walpurgis Night celebration.
