"...the rituals surrounding souling, in which supplicants moved from door to door asking for food in return for a prayer for the dead, bear a resemblance to modern Halloween customs, especially since soulers went from house to house with hallowed-out turnip lanterns, whose candle connoted a soul in purgatory...souling customs offer a clue to the survival of Hallowmass in England after the Protestant Reformation."
