It is an old Slavic holiday, dating the pagan times. There used to be night revels, during which people performed different rites: herbs and flowers gathering, twining wreathes, divination, swimming. And there always was a huge fire, over which girls and guys were supposed to jump holding each other’s hands. According to the legend, only once a year the fern blooms, and it is said that the blooming fern makes one’s wishes come true and helps to find a treasure.
