Perhaps one of the oldest customs is that in connection with St. Mark’s Eve. The belief is still held that those who watch the church porch at the hour of midnight on that eve, will see pass in front of them and enter the church the spirits of all of those friends who will die during the coming year. With some it is held to be a sine qua non that the watcher must sit within the porch; whilst others hold four cross roads to be equally efficacious, alway provided that the body of one who had committed suicide, with the orthodox stake driven through the chest, had been buried there, that being the end of suicides in the good old days.
It should be borne in mind that there are two slight penalties attached to this porch or cross-road watching.
Firstly should the watcher fall asleep, there is every probability if its being the sleep of death. Should he however, manage to awaken from such a lethargic slumber it doesn’t amount to much, as he will assuredly die within the next twelve months. Secondly, whoever tries this game once must continue to do so ever afterwards. There is no escape; the spell upon them is said to be too strong to withstand.
