Xenophon,
Anabasis — Book 6, Chapter 1
“ But as soon as the libation was ended and they had sung the hymn, up got first some Thracians, who performed a dance under arms to the sound of a pipe, leaping high into the air with much nimbleness, and brandishing their swords, till at last one man struck his fellow, and every one thought he was really wounded, so skilfully and artistically did he fall, and the Paphlagonians screamed out. ”
