That
day is the feast of the last one of the hail-men family – sometimes
interpreted as a brother, Vido, sometimes as a syster - Vida. Only
those who have celebrated the other three brothers are allowed to
participate in that last feast.
The traditional belief is that it
is Vido who punishes sinners. This explains the old Bulgarian saying
"Vidovden will come!" Therefore, if the feast is celebrated, God will
not see the sins and they might be left forgotten.
