" Folk art is, indeed, the oldest of the aristocracies of thought, and because it refuses what is passing and trivial, the merely clever and pretty, as certainly as the vulgar and insincere, and because it has gathered into itself the simplest and most unforgettable thoughts of the generations, it is the soil where all great art is rooted. Wherever it is spoken by the fireside, or sung by the roadside, or carved into the lintel, appreciation of the arts that a single mind gives unity and design to, spreads quickly when its hour is come. "

― W.B. Yeats , The Celtic Twilight: Faerie and Folklore
