“Along with celebration, feasting, and games, people would remember the dead. The dance moved from sacred groves and rivers to graves: there the tryznas* took place, with activities the same as in spring. *Tryzna - the ending part of funerary rites, normally consisting of a sacrifice, military-themed games, a feast to honour the deceased person; turned into a dinner during Christian times. At the same time the term meant the three days the winning army received for plundering and celebration. By some definitions, a fight, a competition, a battle.”
— Mykola Kostomarov on celebration of Yarylo’s holiday, supposedly in late May-early June.
