Happy Solstice! Let your fires be bright!
"On St John's Day, the christianized pagan sun festival in honor of the summer solstice, in which fairies and spirits play so prominent a part in all Celtic countries, just outside a country village a great fire is lit in the centre of the main road and covered over with green branches, in order to produce plenty of smoke, and then on either side of this fire and through the excorcizing smoke are made to pass all the domestic animals in the district as a protection against disease and evil spirits, to secure their fruitful increase, and in the case of cows, abundant milk supply."
- from The Fairy Faith in Celtic Countries, by W.Y. Evans-Wentz, 1911
