Many cultures around the world celebrate the summer solstice. The Russian version of this folk festival (out by a couple of days) is known as Ivan Kupala. Like many other festivals (Christmas, for example), Ivan Kupala combines elements of Christian and pre-Christian, pagan rituals.
RBTH explains the main elements of this holiday with reference to the painting by Ivan Sokolov "The Night of Ivan Kupala" (1856).
