'Celtic' is a magic bag, into which anything may be put, and out of which almost anything may come. Anything is possible in the fabulous Celtic twilight, which is not so much a twilight of the gods as of the reason.
J. R. R. TolkienShadowfax tossed his head and cried aloud, as if a trumpet had summoned him to battle. Then he sprang forward. Fire flew from his feet; night rushed over him. As he fell slowly into sleep, Pippin had a strange feeling: he and Gandalf were still as stone, seated upon the statue of a running horse, while the world rolled away beneath his feet with a great noise of wind.
