A circle of summer traditions is related to the great dog days.

It is believed that there are three days in summer which in the folklore are called dog days (goreshtnitsi). These three days are related to the Christian calendar as well – July 15th, 16th, 17th – St. Martyr Julitta & Cyricus, St. Hieromartyr Athenogenes, St. Great Martyr Marina. On these days no work is to be done, neither on the field, nor in the house, because it is believed that everything people touch will burn down. XXX The third day, July 17th, is believed to be the most dangerous one – Fiery Marina.

The Bulgarians celebrate the day of St. Marina for protection against fire and lightning. In the region of Strandzha there are many chapels and holy springs dedicated to St. Marina. Near Malko Tarnovo there is a cave sanctuary “St. Marina” where wonder-working healing water flows. The entrance to the cave is very narrow and according to old beliefs only “pure” girls with impeccable honor can pass through it.

Out of respect to fire and for protection against its destructive power, in the folklore there exists Palyovden, i.e. the feast day of St. Paul – June 30th. On this day no work is to be done either, because “everything you begin doing, ignites and burns down.”
