Historians agree that a Celtic autumn festival called Samhain was the precursor to modern Halloween. Samhain was a time to celebrate the last harvest of the year and the approach of the winter season. It was also a festival for honoring the dead. One way Celtics may have appeased the spirits they believed still walked the Earth was by leaving treats on their doorsteps.
历史学家们一致认为，凯尔特人庆祝秋收的萨温节是现代万圣节的前身。萨温节是庆祝一年中最后一次收获的时节，也是迎接冬天到来的节日。萨温节还是纪念死者的节日。凯尔特人安抚那些依然在世间徘徊的幽灵的方式之一可能就是在自己的门口留下吃食。
