If any one takes ill at Whitsuntide there is great danger of death, for the evil spirits are on the watch to carry off victims, and no sick person should be left alone at this time, nor in the dark. Light is a great safeguard, as well as fire, against malific influences.
In old times at Whitsuntide blood was poured out as a libation to the evil spirits; and the children and cattle were passed through two lines of fire.
