In Scotland the children cut scary faces into hollowed-out turnips, large rutabagas, or potatoes and inside of them they place a candle inside.
In Scotland they continued to practice their deep-rooted, ancient pagan rites well after the arrival of Christianity in the middle of the sixth century. The Church fathers had become concerned that the popularity of non-Christian festivals was growing at the expense of Christian holy days.

Pope Gregory I, in 601 issued a decree to his missionaries about the faith and customs of the people whom he wanted to convert to Christianity. Gregory knew that it would be impossible to eradicate the beliefs of the natives totally and so suggested to his priests that they "convert" them whenever possible.

If the native people worshipped at a well, or sacred grove, Gregory informed his missionaries to enshrine them to Christ and let the worship continue.

Gregory's successor Pope Boniface IV in 609, declared May 13 All Saints' Day. Unfortunately, while pagans were happy to add All Saints' Day to their calendar, they were unwilling to give up their existing festival of the dead and continued to celebrate Samhain.

Intent on eliminating the ongoing power of the pagan beliefs, Pope Gregory III followed in the footsteps of the earlier Christian leaders and intentionally united the Christian All Saints' Day to the festival of Samhain. He then moved All Saints' Day to November 1, which became more commonly known as All Hallows. Because Samhain had traditionally fallen the night before All Hallows, it eventually became known as All Hallows' Even' or Hallowe'en.
