James George Frazer,
The Golden Bough: A Study in Magic and Religion…
“ Fire kindled by the friction of wood. The Germans of Moravia in like manner still light bonfires on open grounds and high places on Midsummer Eve; and they kindle besoms in the flames and then stick the charred stumps in the cabbage-fields as a powerful protection against caterpillars. On the same mystic evening Moravian girls gather flowers of nine sorts and lay them under their pillow when they go to sleep; then they dream every one of him who is to be her partner for life. ”
